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 either stainless steel or 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.

Excitation: 24 Vdc nominal
    Max: 30 + 0.004 x (loop resistance Ω) Vdc
    Min: 11 + 0.02 x (loop resistance Ω) Vdc
Loop Resistance: 0 to 1000 Ω
Output: 4 to 20 mA (2-wire)
Accuracy: ±0.25% RSS FS at constant temperature (includes linearity, repeatability and hysteresis)
Linearity: ±0.20% FS
Hysteresis: 0.10% FS
Repeatability: ±0.05% FS
Operating Temperature Range: -18 to 80°C (0 to 176°F)
Compensated Temperature Range: -1 to 65°C (30 to 149°F)
Thermal Zero Effect: <±0.02% FS/°F
Thermal Span Effect: <±0.02% FS/°F
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.
Wetted Parts: Air and fluids compatible with 17-4 and 300 stainless steel, FKM, and silicone O-rings
Cavity Volume: 0.27/0.08' pos./neg. port
Case: NEMA 4 (IP65)
Pressure Port: ¼ NPT internal
Electrical Connection: Internal barrier strip with 22.2 mm (0.875') conduit opening
Response Time: 50 ms (water)
Weight: 410g (14.4 oz)

Is it possible to order this customized to provide a 0-5VDC electrical output signal?

Asked by: PD Engineer
There is no 0 to 5VDC version of the transmitter available. You can use an external 250 ohm to convert the 4 to 20mA to a 1 to 5VDC

Does the PX2300-2DI come with a calibration certificate?

Asked by: Max1
The PX2300 Series differential sensor do not normally come with any certification. We may be able to offer a NIST certification at an additional charge. You would need to contact our Sales Dept at

I need details around the mounting bracket for this component (PX2300)

Asked by: jenkiwo
Thank you for your inquiry, The PX2300 Series is supplied with a mounting bracket and two (2) 6-32 x 3/8 hex head screws. First attach bracket to mounting location using holes or band clamp notches available on large section of the bracket. Next, attach the transmitter to bracket by using the two 6-32 x 3/8&rdquo; hex head screws and the two tapped holes located on the underside of the transmitter.

Hello, I just ordered PX2300-1DI and now I want to covert output current into the output pressure. With this regard, could you please share a data sheet/table/ formula for the current to pressure conversion?

Asked by: KM03
Thank you for your inquire. This is a linear output. You would take the output range and divide it by the pressure range to get the output per psi.

Hello, I want to use this transducer just as a regular gauge pressure transducer. I.e. I have one inlet for water which gauge pressure I want to measure. I'm going to leave the other inlet open to atmosphere. Will this work?

Asked by: nepomnyi
Yes it will. If you leave the low port open to the atmosphere the unit will act as a 0 to 1 PSIG range sensor
