Level Sensor Used in Cement Silos

Listing ID #510862

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.
