LM07X Series Armored Liquid Level Transmitter

Product Features

◆There are many options for signals;

◆Anti-interference，Surge protection;

◆The submerged part is fully protected by stainless steel with full welding process.

Product Description

LM07X is a fully welded and sealed product designed for small molecule liquid level measurement. It adopts a high-accuracy and high-stability pressure-sensitive element with a stainless steel isolation diaphragm. Through reasonable structural design and advanced microprocessing technology, it performs comprehensive linear error and temperature drift compensation. The part submerged in liquid is fully protected by stainless steel pipes, and it is made into an integrated product with industrial standard 4～20mA or 0.5～4.5V signals through the full welding process.

Product Application

◆Gasoline, alcohol

◆Small molecules, easily permeable media

◆Liquid level detection, system control
