LM03X Series Split-Type Level Transmitters

Product Features

◆There are many options for signals;

◆Anti-interference，Surge protection;

◆316L diaphragm, explosion-proof housing outlet;

◆Lightning protection, compliant with IEC61000-4-5/Level-4 standard.

Product Description

The LM03X series split-type level transmitters are based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. The product adopts the piezoresistive effect of diffused silicon 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, it is an integrated product that outputs industrial standard signals.

Product Application

◆Waterworks, chemical plants;

◆Sewage treatment;

◆Deep wells, dams;

◆Flood control, irrigation.
