LM09X Series Anti-Corrosion Liquid Level Transmitter

Product Features

◆There are many options for signals;

◆Wide measurement range:0~1~100mH₂O

◆Anti-interference，Surge protection;

◆PTFE housing, resistant to strong corrosion.

Product Description

LM09X series anti-corrosion liquid level transmitters are specially designed for strong corrosion liquid level measurement. The product adopts imported ceramic piezoresistive or capacitive sensors as sensitive elements, and the housing is made of highly corrosion-resistant PTFE or PVDF materials. Cooperating with a dedicated signal conditioning circuit, after comprehensive linear error and temperature error compensation, it is made into a pressure liquid level measurement product with extremely strong corrosion resistance.

Product Application

◆Chemical plants, sewage treatment plants

◆Various acidic liquids and gases except hydrofluoric acid

◆High-temperature media
