  • Choice of Ranges 0.5mWG to 100mWG
  • Option of Pressure Reference Choose between gauge, sealed gauge or absolute
Product Options


The S12S submersible level transmitter provides accurate pressure measurement to as low as 0.5mWG. The stainless steel piezo-resistive silicon pressure sensor improves the stability and resolution of the readings compared to those of other measurement technologies. Temperature compensation is standard in every device and the values are output with the level measurements. Each transmitter is calibrated to a total error band of <±0.1% over -5 to 45°C and supplied with a traceable calibration certificate.

The pressure range and units, cable length and material, O-ring seal material and pressure reference can all be specified when ordering.
