Level Sensor Used In Cement Silos

Min. Order (MOQ) 1 Piece
Brand Protocontrol Instruments

Protocontrol offers level sensor to be used in cement silos.it is a rf capacitanceadmitance type level sensor. The rf level switch operates on the basis of rf absorption. The electronic unit generates a sinusoidal wave, applied to the electrode creating a field around it. Rf environment absorption changes (electrical loss) around the electrode are reflected on the changes of generator supply current. Such changes caused by increase in level is amplified and used to actuate the relay. Special coat-guard amplifier is incorporated in the circuit, which will ignore the effect of deposition. The rf admittance type, point level switch, designed with special sensing probe, using special shield coat-guard circuit and three element probe. The level switch is immune to the material built-up on the probe and material bridging between the probe and hopper wall.

Chute Blockage Detector

Min. Order (MOQ) 1 Piece

Protocontrol offers chute block switches for different applications. Following are few models. 1. Rf admittance disc probe : suitable for sensing material jamming in a compact chute. Ideal when you want to mount the sensor at the bottom of the hopper. As the disc probe does not come in the path of the material it does not block the passage and hence does not affect the material flow. Ideal for almost every material solid, powder, granule, dry and wet having particle size up to 30 mm 2. Rf admittance rod probe : the probe is to be inserted in the walls of hopper at required level point. When material level rises and touches the probe the contact is actuated. as the probe is to be inserted in the hopper user has to ensure proper location for minimum abrasion. Provide proper canopy for long use. 3.rf admittance rope probe : the probe is to be hanged from the top in the hopper. The probe length is selected such that the bottom tip reaches at required level point. When material level rises and touches the probe the contact is actuated. as the probe is to be hanged in the hopper user has to ensure that the falling material flow does not fall directly on the sensor. 4. Tilt probe: the tilt probe is to be hanged from the top in the hopper or supported on the walls of hopper at required locations. When material level rises, makes a cone in the hopper. When the material touches the probe and the probe gets tilted, the contact is actuated. Suitable for almost every material solid, powder, granule but only for dry free flowing solids. as the probe is to be hanged in the hopper user has to ensure that the falling material flow does not fall directly on the sensor. to quote proper model pf chute jam device: please inform us size of hopper, chute ( please send drawing of chute )mounting location and suitabilitymaterial to be sensed and its particle sizeconfirm the material is with moisture contains or free flowingsupply voltagethe controller is to be located with the sensor or remote type ( to overcome vibration )ensure that the sensor is protected in hopperabrasion properties of material ( to prove suitable coating on sensor probe ).

Ultrasonic Level Transmitter

Min. Order (MOQ) 1 Piece

Protocontrol offers ultrasonic level transmitter for level sensing applications. It is low cost, non contact type level measurement technique. The analogue op (4-20 ma, 20-4 ma) is used for indication and control purpose. The sensor is to be mounted on tank or hopper, the op signal can be processed at field or in control room for control action. Various models are offered for sensing range up to 50 meters for liquid application. For solids application the range is approx 25 mtrs. an ultrasonic pulse is transmitted from the sensor face. The pulse travels to the surface being monitored and is reflected off this surface back to the sensor. The time of flight is divided by 2 and converted to an output signal directly proportional to the material level ultrasonic level transmitter can be used in food and beverages industries, water wastewater treatment plants, chemicals and oils.

RF Admittance Type Level Switch

Min. Order (MOQ) 1 Piece

We are offering rf admittance type level switch.protocontrol make rf admittance type level switch with disc probe is basically used for sensing the chute blockage in the hopper. It senses jammed condition of the hopper due to clogging at the discharge points. Switch is used for sensing chute jamming of cement, lime, iron ore, food stuff, milk powder, flour, salt, plastic granules and salt. the sensor is to be mounted in the hopper with the help of flange. The heavy duty rugged design makes it ideal for sensing material clogging of hoppers of iron ore, sand, cement and food grains. the disc probe is fabricated out of ss material and provided with teflon insulation. The heavy duty ss probe withstand the abrasion of material provides effective sensing. This level switch designed with two parts. It designed with special sensing probe using special shield coat guard circuit, which will ignore effects of deposition on the probe. control circuit can be integral with sensor probe or it can be mounted remotely if temperature at the product is higher that 100 degree cent. this level switch is suitable for highly dusty environment. It is also simple to install and easy to maintain. when the electronic circuit is integral with probe, control circuit is housed in cast al, ip 65 enclosure fitted on the sensor itself. The control circuit can also be mounted at remote if the process temp is more than 100 degree cent. Control supply can be 230 v ac, 50 hz (standard) .other voltages like 110 v ac, 24 v dc are available on request. the output is in the form of 2 co potential free relay contact. 5 amp resistive at 230v ac. switch have having facility of built in on and off nuisance delays of 2 to 20 sec. The switch can be programmed at site for top or bottom level monitoring with the help of selector switch.

Acid Level Sensor

Min. Order (MOQ) 1 Piece

Protocontrol offers level sensor for acids. It is based upon the principle of conductivity. For sensing level of conducting non sticky clear liquids like water, Acid, Salt & various chemicals, Sugar solutions, Milk, Juice etc. Features :1.Simple, low cost level controller2.Automatically controls liquid levels in any container.3.Quick installation4.Low current operated circuit ensures personnel safety.5.Wide range of electrodes with different mounting configuration, constructions to suitevery application. Operating principle :A conductive Level switch operates on the base of conductive principle. These are equipped with two or more electrodes (one is ground and others are sensing electrodes). When a conductive fluid comes in contact with two or more of sensing electrodes, an electric circuit is completed. A very small alternating voltage is applied to two probes tips. The circuit gets closed by liquid when liquid touches the probe tip. The voltage & currentused are so small that no dangerous shock can occur. The use of alternating voltage prevents deposition and electrolysis.

Vibrating Rod Level Switch

Min. Order (MOQ) 1 Piece

We are offering high durability vibrating rod level switch. protocontrol now offers vibration rod type level switch. This switch is used to detect minimum or maximum level in bins, silos and hoppers filled with any kind of easy flowing solids, e.g. Granules or pellets like grains, granular plastics, foods, etc. The vrls is ideal switch for detecting level of liquids with bulk densities of 20 grams per litre and higherthe electronic circuit when powered excites the stainless steel rod of the probe to vibrate on its resonance frequency. When material covers the rodof the probe the vibration stops. This is sensed by the electronic circuit which forces its relay to switch. When the rod gets uncovered, the vibrationrestarts and the relay switches back. features:1) this switch is easy to install2) requires no calibration3) no re-adjustment is required as it is unaffected by environmental changes e.g. Temperature, pressure, humidity. 4) no maintenance required as the vibration rod has a self cleaning effect. 5) it is highly durable as contains no moving parts. 6) the rod probe eliminates bridging problem, where material builds a bridge from one rod to the other (in vibrating fork)7) rod length can be from 150 mm to max 3000 mm. 8) the design is fail-safe design i.e. If power supply fails the relay drops
