GENERAL INFORMATION
PS98i/PS9800 INSTRUCTIONS
The PS98i/PS9800 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.
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.
Dimensions
8.44” (21.4 cm)
These sensors are thermally compensated, making them
great where water temperatures vary, as they are thermally
stable (2% over 50 degrees standard).
Both the PS98i and the PS9800 measure pressure, while the
PS9800 can optionally be factory congured to measure
temperature, also.
These industry standard, 2-wire, 4-20mA devices oer
reverse polarity protection, under- and over-current
limitation, and built-in transient protection.
