Features:
• No moving parts, it is r ed and robust instrument.
• No dead band or dead zone like float based/ultrasonic instruments.
• Trim-Pots for span and zero adjustment.
• Plug and play with reference probe and rod.Remote electronics as option with 2 Metre long coaxial cable.
• Standard enclosure weather proof-cast Aluminium or Nylon 66.Flame proof as optional.
• Our new introduction is Micro processor based Blind Transmitter(available only in weather proof version) with Push Button Teach-in facility and damping arrangement.
• Suitable for operation from 12 to 32 VDC, with reverse polarity protection.Standard output 4-20mA.Voltage output of 0-10 optional. (For 12 V input supply output 0-5V and with 24 V supply output 0-10V).

Application:
A capacitance 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.

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, r ed 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.
