Capacitance Level Transmitter

Capacitance Level Transmitter is formed between the probe and the vessel wall. As the level of the measuring medium rises or falls capacitance between the probe and vessel wall changes proportionately. A high-frequency sine wave is applied between the probe and tank wall. A change of medium level will induce a change in the current of the applied sine wave. When the capacitance in the vessel increase, the impedance will decrease and the current will increase, and vice-versa. (Z=Resistance, C=Capacitance, F= Frequency).Head-mounted electronics convert the capacitance variation to a 4-20mA signal for long-distance transmission. It is provided with trim pots for SPAN and ZERO adjustments. With no moving parts, it is free from wear and tear, rugged, and robust in construction. No dead zone like float-based instruments.Technical SpecificationKabir makes a Capacitance type 3 wire Level transmitter Model (CLT-1) with non-insulated probes for non-conductive liquids or PTFE Teflon insulated probes for conductive liquids.While sending inquiries for capacitance type level transmitters, please furnish following information to enable us to submit a suitable offer-:Name of service Medium/LiquidDielectric constant of the medium.Operating Temperature and pressure.
