Product Description

LM05X series submersible small-diameter liquid level transmitter is an integrated product based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It adopts the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert static pressure into electrical signals. Cooperating with a dedicated digital circuit, after signal processing such as signal amplification, linear compensation, anti-interference, and surge protection, it outputs industrial standard signals.

Product Application

◆Waterworks, chemical plants

◆Wastewater treatment

◆Deep wells, dams

◆Flood control, irrigation
