The concept of temperature :

• From a physical point of view, heat is a measure of the energy contained in a body due to the irregular motion of its molecules or atoms. Just as a tennis ball possesses more energy with increasing speed, so the internal energy of a body or gas increases with increasing temperature. Temperature is a variable which together with other parameters such as mass and specific heat describes the energy content of a body.
• The basic measure of temperature is the degree Kelvin. At 0?K(elvin) the molecules of every body are at rest and it no longer has any thermal energy. There is therefore no possibility of negative temperatures since there cannot be a state of lower energy.
• In every-day use it is general practice to use the Celsius scale (previously Centigrade). Its zero is placed at the solidification point of water since this point is very simple to reproduce in practice. Now 0?C is by no means the lowest possible temperature as everyone knows from experience. By extending the Celsius scale to the lowest possible temperature where all molecular movement ceases we reach a temperature of -273.15 degrees.
• Man has the ability to measure temperatures through his senses within a limited range. However, he is incapable of accurate reproduction of quantitative measurements. The first forms of quantitative temperature measurement were developed at the beginning of the 17th century in Florence and depended on the expansion of alcohol. The scaling was based on the maximum summer and winter temperatures. A hundred years later the Swedish astronomer Celsius replaced this by a scale based on the melting and boiling points of water. This offered the opportunity for a thermometer to be scaled at any time and reproduce readings at a later time.

Measuring temperature electrically :

• The measurement of temperature is important in many applications, such as, building control, food processing and the manufacture of steel and petrochemicals. These very different applications require temperature sensors of different physical construction and often different technology.
• In industrial and commercial applications the measurement point is frequently far away from the indication or control point. Often there is a requirement for further processing of the measurement in controllers, recorders or computers. Such applications are unsuitable for directindicating thermometers as we know them from every-day use but require devices which convert temperature into another form, an electrical signal. To provide this remote electrical signal it is common practice to employ RTD?s. thermistors and thermocouples.

RTD?s  :

• RTD's employ the property that the electrical resistance of metals varies with temperature. They are positive temperature coefficient (PTC) sensors whose resistance increases with temperature. The main metals in use are platinum and nickel. The most widely used sensor is the 100 ohm or 1000 ohm RTD or platinum resistance thermometer.
• RTD?s are the most accurate sensors for industrial applications and also offer the best long-term stability. A representative value for the accuracy of a platinum resistance is +0.5 percent of the measured temperature. After one year there may be a shift of +0.05?C through aging. Platinum resistance thermometers can cover temperature ranges from -200 to 800?^oC.

• The variation of resistance with temperature
  • The electrical conductivity of a metal depends on the mobility of the conduction electrons. If a voltage is applied to the ends of a metal wire the electrons move to the positive pole. Faults in the crystal lattice interfere with this movement. They include foreign or missing lattice atoms, grain boundaries, and atoms on interlattice positions. Since these fault positions are independent of temperature they produce a constant resistance. With rising temperature the atoms of the metal lattice exhibit increasing oscillations about their rest positions and thereby impede the movement of the conduction electrons. Since this oscillation increases linearly with temperature, the resistance increase caused by it depends as a first approximation directly on the temperature.
  • In industrial measurement the resistance material platinum has found general acceptance. Its advantages include chemical stability, comparatively easy fabrication (especially for wire manufacture), the possibility of obtaining it in highly pure form, and electrical properties which can be reproduced. These characteristics have made the platinum resistance sensor the mostuniversally interchangeable temperature sensor.

Thermistors :

• Thermistors are made from certain metal oxides whose resistance decreases with increasing temperature. Because the resistance characteristic falls off with increasing temperature they are called negative temperature coefficient (NTC) sensors.
• Due to the nature of the basic process the number of conducting electrons increases exponentially with temperature; the characteristic therefore exhibits a strongly rising form. This pronounced non-linearity is a disadvantage of NTC resistors and limits their useful temperature span to about 100^oC. They can of course be linearised by an automation computer. However, accuracy and linearity generally do not meet the requirements over larger measurement spans.Their drift under alternating temperatures is also larger than for RTD?s. Their field of use is limited to monitoring and indicating applications where the temperatures do not exceed 200^OC. In such simple applications they are actually preferable to more expensive thermocouples and RTD?s in view of their low cost and the comparatively simple electronic circuitry required. In addition they can be produced in very small designs with a fast response and low thermal mass. temperature. In industrial measurement the resistance material platinum has found general acceptance. Its advantages include chemical stability, comparatively easy fabrication (especially for wire manufacture), the possibility of obtaining it in highly pure form, and electrical properties which can be reproduced. These characteristics have made the platinum resistance sensor the most universally interchangeable temperature sensor.

Thermocouples :

• Thermocouples are based on the effect that the junction between two different metals produces a voltage which increases with temperature. Compared with resistance thermometers they offer the clear advantage of a higher upper temperature limit, up to several thousand degrees Celsius. Their long-term stability is somewhat worse (a few degrees after one year), the measuring accuracy is slightly poorer (on the average +0.75% of the measurement range). They are frequently used in ovens, furnaces, flue gas measurements and other areas with temperatures above about 250^oC.

• The thermoelectric effect :
  • When two metals are connected together, a thermoelectric voltage is produced due to the different binding energies of the electrons to the metal ions. This voltage depends on the metals themselves, and in addition on the temperature. In order for this thermal voltage to produce a flow of current the two metals must of course be also connected together at the other end so that a closed circuit is formed. In this way a thermal voltage is produced at the second junction.
  • The thermoelectric effect was discovered in 1822 by Seebeck, and as early as 1828 Becquerel recommended the use of a platinum-palladium thermocouple for temperature measurement.
  • If there is the same temperature at the two junctions there is no flow of current since the partial voltages produced at the two points cancel each other. With different temperatures at the junctions the voltages generated are different and a current flows. A thermocouple can thus only measure temperature differences.
  • The measurement point is the junction which is exposed to the measured temperature. Thereference junction is the junction at the known temperature. Since the known temperature isusually lower than the measured temperature, the reference junction is generally called the coldjunction. In order to calculate the actual temperature at the measurement point the coldjunction temperature must be known.
  • Older instruments used a thermostatically controlled junction box to control this cold junction temperature at a know value such as 50C. Modern instruments use a thin film RTD at the cold junction to determine its temperature and calculate the measurement point temperature.
  • The voltage produced by the thermoelectric effect is very small and amounts to only a few microvolts per degree Celsius. Thermocouples are therefore not generally used within the range -30 to +50?C since the difference from the reference junction temperature is too small here to produce an interference-free signal.

RTD Wiring :

• In the resistance thermometer the electrical resistance varies with temperature. For evaluating the output signal a constant current is passed through it and the voltage drop across it is measured. For this voltage drop follows Ohm's Law, V=IR. The measuring current should be selected to be as small as possible in order to avoid heating of the sensor. It can be taken that a measuring current of 1 mA does not introduce any appreciable errors. This current produces a voltage drop of 0.1 V in a Pt 100 at 0?C. This signal voltage must now be transmitted through the connecting cables to the indicating or evaluation point with a minimum of alteration.

There are four different types of connecting circuit :

• 2-wire circuit : The connection between the thermometer and the evaluation electronics is made with a 2 conductor cable. Like any other electrical conductor this cable has an electrical resistance which is placed in series with the resistance thermometer. The two resistances are therefore added together which is interpreted by the electronics as an increased temperature. With longer distances the line resistance may amount to a few Ohms and produces an appreciable shift in the measured value.
• 2-wire transmitters : The problems of the 2-wire circuit as described above can be avoided without the use of a multiconductor cable by employing a 2-wire transmitter. The transmitter converts the sensor signal into a normalized current signal of 4 - 20 mA which is proportional to temperature. The supply to the transmitter is also run through the same two connections, using a base current of 4 mA. The 2-wire transmitter offers the additional advantage that the amplification of the signal greatly reduces the effects of external interference. There are two arrangements for positioning the transmitter. Since the distance for the unamplified signal should be kept as short as possible the amplifier can be mounted directly on the thermometer inside its terminal head. This optimum solution is some times impossible for constructional reasons or the consideration that the transmitter may be difficult to reach in case of a fault. In such situations a rail mount transmitter is mounted inside the control cabinet. The advantage of improved access is bought at the expense of the longer distance over which the unamplified signal has to travel.
• Thermistor Wiring : The resistance of thermistors is is normally several orders of magnitude greater than any lead resistance. The lead resistance therefore, has a negligible effect on the temperature reading and thermistors are almost always connected in a 2-wire configuration.
• Thermocouple Wiring : Unlike RTD?s and thermistors thermocouples have plus and minus legs so polarity must be observed. They can be directly connected to a local 2-wire transmitter and copper leads can be run back to the receiving instrument. If the receiving instrument is capable of accepting thermocouple inputs directly you must use the same thermocouple wire or thermocouple extension wire all the way back to the receiving instrument.

Choosing the right sensor for building automation :

• Platinum RTD?s are the most accurate and stable sensors over a long time period. Their cost to the trade is typically about Cdn$5 more per point than thermistors. Some automation panels do not accept RTD?s directly and with these panels they must be used with temperature transmitters which add about Cdn$50.
• Thermistors are not quite as accurate or stable as RTD?s but they are easier to wire, cost slightly less and almost all automation panels accept them directly. Note though that thermistors are available in many different base resistances and with many different curves. You must specify the right thermistor for the panel you will use.
• Thermocouples are widely used in industrial applications because they work reliably at very high temperatures and are less expensive than RTD?s. In building automation they are rarely required because most temperatures measured are less than 100C. They are, however, used frequently in flue gas measurements in conjunction with 2-wire transmitters.
• Consultants on some jobs specify platinum RTD?s because of their improved accuracy and long term stability. If the automation panel you are using does not take RTD?s directly use them in conjunction with a 2-wire transmitter to meet the specification.

Description :

• We design and manufacture automatic power factor correction panel. (contactor switching) Power Factor is ratio which represents actual power dissipated in A.C. circuit to the product of R.M.S. voltage and current. The phase difference between voltage and current is caused by reactance in circuit and represents power that does no useful work.
• Power factor is low in industrial settings where most of the plant energy is used to power electric motors. It is lowest when the induction motors tend to be oversized and under-loaded. A lagging (less than 1.0) power factor causes some additional energy loss because more current is required to deliver a required amount of power. Correcting power factor can be an appropriate and costeffective measure.
• Inductive load is major cause of poor factor and which is responsible for unnecessarily power loss, hence it results in rise of electricity bills of industrial, commercial consumer so Reactive power compensation is very need of today’s industries. We can easily control and maintain power factornear to unity with Automatic Power Factor Correction Panel.

Details : Melt Pressure Sensors are utilized in a wide variety of industries, including polymer, food, medical, and chemical extrusion processing applications. Melt Pressure Sensors are available in two unique Styles. The CT style is the classic melt pressure sensor with a 6" rigid stem and 18" of flex capillary for optimum thermal isolation. The RT style offers only a 6" rigid stem. Both styles come standard with the 6-pin Bendix style bayonet connector, and a 1/2-20 UNF mounting thread. Our Melt Pressure Sensors are fully interchangeable with all other major brands Melt Pressure  Transducer

Description : The Melt Pressure Transducer is ideal for general purpose Melt pressure applications. The unit features the industry standard 3.33 mV/Volt output and offers pin-to-pin compatibility with all competitors models utilizing the Bendix style 6 pin bayonet connector.The Melt Pressure Transducer comes standard with a 6" rigid stem, 18" of flexible capillary, and a 1/2-20 UNF thread for mounting in standard transducer mounting holes.Melt Pressure Transducers are measuring instruments that are subject to damage if mishandled, improperly installedor dropped.

Features :

• 3.33 mV/Volt full scale output
• Accuracy +/- 0.25%, 0.5%, 0.1%
• Internal 80% shunt calibration
• Melt Pressure Transducer
• All welded all stainless steel construction
• Melt Pressure Transducer Diaphragm : The Melt Pressure Transducer is a sealed system. The sensing diaphragm is the most important component of the transducer. The standard diaphragm is of a one piece construction, machined from type 15-5PH stainless steel, with a proprietary coating designed to increase durability. It has a nominal thickness of 0.0050 inches. If the sensingdiaphragm becomes damaged in any way i.e.: dented, gouged or deformed, the transducer will no longer provide accurate readings and should be returned to for repair and/or replacement. See the repair and re-calibration information in the Technical section of our website for further details.
• Melt Pressure Transducer Mounting Hole : A poorly prepared or machined transducer mounting hole is one of the main causes of damage to the transducer. Extruder barrel wear should be monitored periodically. As the extruder barrel wears, the transducer diaphragm will move closer and closer to the barrel bore until it is flush with the sidewalls. Once the diaphragm is flush with the extruder barrel, it will wear at the same rate as the extruder barrel. To alleviate this problem, recommends that the transducer be recessed 0.0175" from the barrel bore. A copper spacer can be manufactured or purchased (to seal on the 45 degree seating surface) that will act as a separator backing off the transducer diaphragm from the inside barrel bore. If the transducer diaphragm protrudes into the extruder barrel, it is subject to unnecessary rapid wear and is subject to permanent damage by a passing screw flight.
• Melt Pressure Transducer Mounting Hole Threads : The transducer mounting threads should be 1/2-20UNF-2B. M18, M22, ¾ The mounting hole should be cleaned and inspected prior to the installation or reinstallation of a transducer. The use of a high temperature anti-seize compound will help in prevent galling and will allow easy removal of the transducer. Copper graphite anti-seize compounds are recommended.
• Melt Pressure Transducer Mounting Torque : Melt Pressure Transducers are capable of being installed at a mounting torque of up to 500 inch/pounds without damage or zero shifts; an adequate seal is generally achieved with a mounting torque of 100-200 inch/pounds. This can be accomplished by first installing finger tight and then tightening the transducer a quarter turn with a wrench. Excessive mounting torque will cause seizing and make the transducer difficult to remove.
• Melt Pressure Transducer Operating Temperatures : The Melt Pressure Transducer diaphragm is capable of operating at temperatures up to 750^oF. The transducer electronics are capable of operating at temperatures of up to 150^oF. It is important that the electronic housing not be exposed to temperatures above 150^oF.
• Melt Pressure Transducer Affects of Cold Starts : One of the most common causes of Melt Pressure Transducer diaphragm damage is cold starts. A combined temperature and pressure transducer can be used to insure that the extruder barrel is up to temperature prior to the rotation of the extruder screw.
• Melt Pressure Transducer Removal or Replacement : The transducer should only be removed or replaced while the machine is at operating temperature and the polymer is liquid. Removing the transducer from a cold extruder will cause diaphragm damage due to polymer adhesion. A transducer should never be installed into a mounting hole where there is the presence of solid polymer. If the diaphragm is forced against a solid, the transducer can easily be overloaded and left with a very high zero offset, often too high to be rezeroed.
• Melt Pressure Transducer Diaphragm : If the transducer is removed warm from the machine, the diaphragm can be easily be cleaned with a soft cloth. If there is solid polymer present, a fluidized bed cleaning system can be used. Never use a wire brush, knife, or torch to clean the tip of a transducer.
