LM01X Series Submersible Level Transmitters

Product Features

◆There are many options for signals;
◆Full welding process, durable;
◆Anti-interference and surge protection;
◆Lightning protection, compliant with IEC61000-4-5/Level-4 standard.

Product Description

The LM01X series submersible level transmitters are based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. They adopt the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert static pressure into electrical signals. Combined with a dedicated digital circuit, after signal processing such as signal amplification, linear compensation, anti-interference, and surge protection, they are integrated products that output industrial standard signals.

Product Application

◆Waterworks,chemical plants;
◆Sewage treatment;
◆Deep wells,dams;
◆Flood control, irrigation.
