Product Details

New pruduct liquid level sensor
Principle of liquid level sensor:

Input type (Hydraulic pressure) liquid level transmitter adopt high performance diffused silicon piezoresistive pressure sensor as measuring element, after the high reliability of amplification circuit and precise temperature compensation, convert the gauge pressure or absolute pressure of the measured medium into standard voltage or current signals.

This product has the advantages of small volume, convenient use and installation, directly put into the water, that can measure liquid height from the surface to the end of the liquid level transmitter.

Feature of liquid level sensor:

Use advanced circuit processing technology, stable performance and high sensitivity

A variety of range, maximum measuring 200m (Water column pressure)

Adopting the 316L stainless steel diaphragm, applicable to a variety of measuring medium

Flexible configuration, select different configuration according to requirements.

Reverse polarity and overvoltage protection

Shock and lightning protection design

Laser trimming resistance temperature compensation, zero and range can be adjusted on site

Anti-Corrosion, suitable for a variety of medium

Overload and strong anti-interference ability, stable performance
