Product Details
IP68 Submersible Pressure Transducer for Measure Liquid Level with Display
Production Introduction:
QST-202 liquid level transmitters are consisting of well-sealed immerging oil-filled liquid level transducers and special circuit for manometers. Have characteristics of high precision, good stability, long life and easy to fix. Adopt special sealed configuration, so with good capability of anti-leakage.
According the relation between pressure, density and liquid level, the liquid level transducers measure the liquid pressure which in direct ratio with depth of liquid, then via amplificatory circuit, the measured pressure is transferred to standard 4~20mA current signal(or standard voltage signal).
Feature:
◆Wide measurement range
◆Sealed structure: IP68.
◆Various output signal
◆CE Certificate
◆Marking : ExiaIICT6
◆Integrated construction, LED display can be choosing.
