SLS300A Submersible liquid level transmitter

SLS300A series input liquid level transmitter is an integrated product based on the principle that the measured liquid static pressure is proportional to the height of the liquid.

SLS300A series input liquid level transmitter is an integrated product based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the Piezoresistive effect of diffused silicon or ceramic sensing elements to convert the static pressure into electrical signals, and then cooperates with special digital circuits to output industrial standard signals through signal amplification, linear compensation, interference resistance, surge protection and other signal processing.

They are widely used in waterworks, chemical plants, sewage treatment, deep wells, dams, flood control, irrigation.
