SLS300D Submersible Deep Well Level Sensor

SLS300D series deep well level sensor is an integrated product based on the principle that the measured liquid static pressure is proportional to the height of the liquid.

SLS300D series deep well level sensor 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.

Deep Well Level Sensor features

  • Full welding process, durable and durable;
  • Anti interference and anti surge protection;
  • Wide measurement range: 0-300m-50mH2O;
  • 316L stainless steel isolation diaphragm, integrated design;
  • Lightning protection, in accordance with IEC61000-4-5/Level-4 standards;
