SLS300B Sewage and sludge Level Transmitter

SLS300B series input liquid level transmitter is based on the principle that the measured static pressure of the liquid is proportional to the height of the liquid.

SLS300B series input liquid level transmitter is based on the principle that the measured static pressure of the liquid is proportional to the height of the liquid. The product uses the Piezoresistive effect of 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, anti-interference, surge protection and other signal processing.

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

Sludge Level Transmitter features

  • Wide measurement range: 0-10m-100mH2O;
  • Multiple output signals are optional;
  • Anti interference and anti surge protection;
  • Ceramic diaphragm, anti-corrosion;
  • Lightning protection, in accordance with IEC61000-4-5/Level-4 standards;
