Some pressure measurement applications are beneath the surface of the ocean, perhaps on an undersea oil installation or on ROVs or SUVs. The challenges for completely submersible pressure transmitters are the same for all of these situations: preventing liquid from entering the sensor is essential. Additionally, internal condensation can damage the electronics, or corrosion can literally eat through the case of the sensor.

Submersible Pressure Transmitters

When dealing with a hostile underwater environment the inside of the pressure transmitter must be kept completely dry to the maximum specified depth. The deeper the submersion, the higher the pressure encountered and the greater the integrity of the seals needed to resist the external hydrostatic pressure.

The Right Submersible Pressure Transmitter for Your Applications

The GT21XX Series liquid level pressure transmitters from Stellar Technology feature fully welded construction and molded elastomer or polyurethane seals to provide a liquid-tight seal and prevent the intrusion of water via the electrical connection between the sensor and the cable.

Rugged and reliable strain gage sensing elements and advanced electronics provide high-level signals while also providing excellent thermal characteristics, resistance to shock and vibration, and infinite resolution.

The GT21XX Series offers a wide spectrum of operating ranges, stainless steel welded construction and a large selection of standard electrical terminations and nosepieces.

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.
