OMEGA’s PX2300 Series
high-output, low differential pressure
transducers are compatible with
most media, from dry air to corrosive
liquids. All wetted parts are
stainless steel with elastomer seals.
The electronics are housed in a
NEMA 4 (IP65) enclosure. A
high working pressure and high
overpressure ratings ensure
dependability in harsh industrial
environments. These transducers
are ideal for measuring pressure
drop across filters and other
process devices.

High Pressure Port
Sensor: Capacitive
Maximum Line Pressure: 250 psig
Maximum Overpressure:
High Side: 1 to 5 psi = 20 x FS,
10 to 25 psi = 10 x FS, 50 psi = 5 x FS,
100 psi = 2.5 x FS
Low Side: 2.5 x FS (shift recoverable)
The zero will shift slightly when high
differential pressure is applied. The shift
may be as much as ±10% FS with
overpressure applied to the low port.
(Other parameters will not shift.) The
shift may be recovered by a positive
overpressure or if the overpressure is
always in one direction, the user may
apply this pressure to pre-set the sensor.
Subsequent overloads of less pressure
will not cause any further shift.
