LM08X Series Pressure-Guided Liquid Level Transmitter

Product Features

◆Wide measurement range:0～1m～20mH2O；

◆There are many options for signals;

◆Anti-interference and surge protection;

◆Suitable for high-temperature and small-range measurement.

Product Description

The sensor part and signal processing circuit of the high-temperature gas-guided liquid level transmitter are designed inside the junction box. The gas in the gas collection cylinder submerged in the liquid contacts the medium, and the pressure is transmitted to the sensor through the pressure guiding tube, avoiding direct contact between the sensor and the measured medium. This product is specially designed for high-temperature or strongly corrosive liquids, effectively solving the problem of difficult level measurement of high-temperature liquids. It is particularly suitable for measuring the level of medium and small-range and strongly corrosive media.

Product Application

◆High-temperature liquid media

◆Corrosive media

◆Liquid level detection, system control
