Seametrics PS98i 4-20mA Submersible Pressure Transmitter

Description

Seametrics PS98i 4-20mA Submersible Pressure Transmitters are rugged and accurate with great noise immunity, transient protection, and thermal performance. These pressure sensors have been designed to provide trouble-free submersible operation in liquid environments. The pressure is measured with an extremely rugged and stable piezo-electric, media-isolated pressure element and calibrated with well-established calibration procedures and NIST traceable equipment.

The PS98i sensors are thermally compensated, making them great where water temperatures vary, as they are thermally stable (2% over 50 degrees standard). These industry-standard, 2-wire, 4-20mA devices offer reverse polarity protection, under and over-current limitation, and built-in transient protection.
