Capacitance Type Level TransmitterCapacitance LevelTransmitter can be used for conductive as well as non conductive liquids. It is offered with PTFE sleeve for better insulation & to withstand high temperature in conductive tanks the insulated probe acts as one electrode & the tank wall as another electrode, any change in liquid level the dielectric value will change thereby changing the capacitance value proportional to the liquid level. In the case of nonconductive tanks, a reference probe is provided as a ground electrode. The output is 4-20mA,

A Capacitance Type 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. From when the capacitance in the vessel increase, impedance will decrease and current will increase and vice-versa. (Z=Resistance, C=Capacitance, F= Frequency)
Head mounted electronics converts the capacitance variation to 4-20mA signal for long distance transmission. It is provided with trimpots 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. It must be ensured that the probe is parallel to the tank wall throughout it's length. Make MAHALAXMI INSTRUMENTSSalient Features:
- Two parts isolated design-Electronic Module can be easily separated without removing the probe and without necessity of process shut down. So module replacement is easy
