Excellent media compatibility
Shock and vibration resistant
P900 Series Strain Gauge Pressure Transducers are
premium grade sensors that provide highly precise
measurement of absolute, vented gauge, or sealed
gauge pressures over wide temperature ranges.
Standard versions of this transducer use a 17-4 PH
stainless steel diaphragm to sense pressure (Inconel
versions are available for operation in highly corrosive
environments). The deflection of the diaphragm is
transferred to a double cantilever beam by a force
transfer rod. Strain in the beam, and therefore, input
pressure is measured by four foil strain gauges.
An all-welded construction provides high reliability and
stability. Capable of sensing extremely small changes of
applied pressure, the transducers are relatively
insensitive to vibration, attitude, and shock.
The P900 Series Pressure Sensors are available in a
range of electrical inputs and outputs. Zero and span
potentiometers are available as a special option with the
P940, P950, P960, and P990 models. Non-standard
pressure ranges are available in all models of the P900
Series.
