Resistance thermometers, also calledresistance temperature detectors(RTDs), aresensorsused to measure temperature by correlating the resistance of the RTD element with temperature. Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it. The RTD element is made from a pure material, typically platinum, nickel or copper. The material has a predictable change in resistance as the temperature changes and it is this predictable change that is used to determine temperature. They are slowly replacing the use ofthermocouplesin many industrial applications below 600C, due to higher accuracy and repeatability.

Athermocoupleis an electrical device consisting of two different conductors formingelectrical junctionsat differingtemperatures. A thermocouple produces a temperature-dependentvoltageas a result of thethermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type oftemperature sensor.^[1]

Commercial thermocouples are inexpensive, ^[2]interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation. The main limitation with thermocouples is accuracy; system errors of less than one degreeCelsius(C) can be difficult to achieve.^[3]

Thermocouples are widely used in science and industry; applications include temperature measurement forkilns, gas turbineexhaust, diesel engines, and other industrial processes. Thermocouples are also used in homes, offices and businesses as the temperature sensors in thermostats, and also as flame sensors insafety devicesfor gas-powered major appliances.

The sensor, based on a zirconium oxide cell, is mounted at the tip of the probe that is inserted in the flue duct. The resulting direct, in situ measurement provides accurate and rapid oxygen reading for combustion control optimization and emissions monitoring.

When selecting a pressure gauge, it is important to consider the following factors to ensure safety and accuracy:

1. Pressure fluid composition

2. Pressure fluid temperature

3. Ambient conditions

4. Pressure range

5. Conditions affecting wear of the system

6. Method of mounting

7. Required accuracy

1. Pressure fluid composition Since the sensing element of a pressure gauge may be exposed directly to the measured medium, consider the characteristics of this medium. It may be corrosive, it may solidify at various temperatures or it may contain solids that will leave deposits inside the sensing element. For pressure fluids that will not solidify under normal conditions or leave deposits, a Bourdon tube gauge is acceptable. Otherwise a Sealgauge or diaphragm seal should be used. A chemical compatibility chart follows this section to aid in the selection of the proper sensing element material.

2. Pressure fluid temperature Steam and other hot media may raise the temperature of the gauge components above safe working limits of the sealed joints. In these cases it is recommended that a siphon, cooling tower or diaphragm seal be used in conjunction with the pressure gauge.

3. Ambient conditions The normal ambient temperature range for WIKA pressure gauges is -40o F to +140o F (-40o C to +60o C) for dry or silicone-filled gauges and -4o F to +140o F (-20o C to +60o C) for glycerine-filled gauges. The error caused by temperature changes is +0.3% or -0.3% per 18o F rise or fall, respectively. The reference temperature is 70o F (20o C). The correction is for the temperature of the gauge, not the temperature of the measured medium. Remote gauge mounting using a diaphragm seal and capillary line is one alternative for applications involving extreme ambient temperature. Moisture and weather effects must also be considered. Liquid-filled gauges prevent condensation build up. For outdoor use, stainless steel, brass or plastic cased gauges are recommended.

4. Pressure range A gauge range of twice the working pressure is generally selected. The working pressure in all cases should be limited to 75% of the gauge range. Where alternating pressure and pulsation are encountered, working pressure should be limited to 2/3 of the gauge range.

5. Conditions affecting wear of the system In applications involving severe pressure fluctuation or pulsation, the use of restrictors and/or snubbers is recommended. In addition, liquid-filled gauges increase the service life of gauges in these conditions. WIKA liquidfilled gauges are generally filled with glycerine. Silicone for larger temperature extremes and Halocarbon for use with oxidizing agents such as chlorine, oxygen and hydrogen peroxide are also available.

6. Method of mounting Radial (LM) and back (CBM or LBM) connections are available for most WIKA gauges. WIKA stocks gauges with standard NPT threaded connections. Other types such as metric threads, straight threads, hose barbs and special fittings are available as a special order. Pressure gauges should be mounted in the upright position. For applications where the gauge is mounted side ways, horizontally or upside down, contact WIKA Customer Service for gauge type compatibility.

7. Required accuracy WIKA stocks gauges with accuracies from 3/2/3% to 0.1% of span (ASME Grade B to Grade 4A). To ensure safe and accurate gauge selection, you must take all of the above factors into consideration.

Athermometeris a device that measurestemperatureor atemperature gradient. A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb on amercury-in-glass thermometer) in which some physical change occurs with temperature, and (2) some means of converting this physical change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer).

There are various principles by which different thermometers operate. They include thethermal expansionof solids or liquids with temperature, or the change in pressure of a gas on heating or cooling. Radiation-type thermometers measure theinfraredenergy emitted by an object, allowing measurement of temperature without contact.

Thermometers are widely used in industry to control and regulate processes, in the study of weather, in medicine, and scientific research.

Some of the principles of the thermometer were known to Greek philosophers of two thousand years ago; by the 18th century, standardized scales allowed the readings of different thermometers inter-comparable.

Extremely short microwave pulses with low emitted power are transmitted by the antenna system to the measured product, reflected by the product surface and received back by the antenna system. Radar waves travel at the speed of light. The time from emission to reception of the signals is proportional to the level in the vessel. A special time stretching procedure ensures reliable and precise measurement of the extremely short transmission periods.The propagation of microwaves is virtually unaffected by the ambient temperature and pressure. Hence these radar sensors are ideal for use under extremely difficult process conditions. Pressures from vacuum up to 160 bar(2320 psi) and temperatures from - 40 . +400 C (-40 . +752 F) are no problem for radar.
