RF Type Level Switch

V. Automat Level Sensors designed to provide fine level information of ... the level & gas people Solids (Powder & Lumps). Liquids and Slurry applications for Point level detection in storage Bins, Silos, Hoppers, Tanks, Chutes and any other vessels / tanks where material is stored, processed and discharged even at high temperature / Pressure / corrosive applications. Features:- • Suitable for conductive and non conductive applications • Fast switching response 1 to 2 sec • High pressure upto 40 kg/cm2 • Works well with fluffy powders application

The oscillator generates low-power RF signal which is used to provide signals equal in frequency, phase and amplitude to both, active section and shield section of the probe. The signal applied to the shield is held constant by use of a compensating amplifier. The detector is then used to compare the fixed signal with active signal which varies with the change of media between the probe and Vessel/ Hopper wall. Difference in the signals compared by the detector cause the output relay to activate. The contacts of the output relay to when activated are used to indicate the presence or absence of material in the vessel / Hopper at the probe level.
