Reliable, Accurate Submersible Pressure Sensors for Industrial Applications

Stellar Technology offers reliable and accurate submersible pressure sensors that can be used in a number of industrial applications. Most commonly, submersible pressure sensors are utilized beneath the surface of the ocean, typically on an undersea oil installation or on ROVs or SUVs.

The biggest application challenge for completely submersible pressure sensors is preventing liquid from entering the sensor. Any internal condensation can damage the electronics, while corrosion can literally eat through the case of the sensor.

Submersible Pressure Transmitters

When implemented in an underwater environment, the inside of the submersible pressure transmitter must be kept completely dry to the maximum specified depth. The deeper the submersion, the higher the pressure encountered and therefore, a  greater resistance to external hydrostatic pressure is needed from the seals.

The Right Submersible Pressure Transmitter for Your Applications

The GT21XX Series liquid level submersible pressure transmitters features fully welded construction and molded elastomer or polyurethane seals. This provides a liquid-tight seal and prevents the intrusion of water via the electrical connection between the sensor and the cable.

The submersible pressure transmitter from Stellar Technology provides high-level signals, infinite resolution, and excellent thermal characteristics. The GT21XX Series is made of stainless steel and offers a wide spectrum of operating ranges and a large selection of standard electrical terminations.

Standard features of submersible pressure transmitters include:

  • ±0.25% Accuracy
  • Removable nosepieces
  • High resistance to shock and vibrations
  • Reliable, long-term stability
  • Equipped with rugged and reliable strain gage sensing elements and advanced electronics

Each is shipped with a comprehensive calibration record with a minimum of 15 calibration references for linearity, hysteresis, repeatability and temperature traceable to NIST as standard.

Optional features of Stellar Technology’s submersible pressure transmitters include:

  • Improved temperature performance
  • Subsea receptacle
  • Low current draw electronics
  • Improved accuracy
