Omega's PX190 Rugged IP67 Compact Pressure Transmitter series is a terrific option for OEM or general purpose applications where an economical choice is needed. These transducers are designed for general industrial and commercial applications where good accuracy and reliability are also important. The PX190 series is constructed with a rugged, compact design that is under 2" - a great fit for small spaces. And with wetted parts made of 17-4PH stainless steel, this transducer has high strength, good corrosion resistance, and good mechanical properties that make it compatible with a wide variety of media. This transducer comes in both voltage and current output options and a variety of pressure ranges that cover gauge pressure from 0 to 700 psi.

Great sensor, details are lacking.
Like the design, but the termination and artificially stiff backer rod in the cable are both sub-par.

Pressure transducer for repair of a machine we use
Good. Works as advertised. Old model was discontinued.

For the PX191 (voltage output signal) transducers, what are the wires? I'm specifically wondering about the number of wires and the gauge as well as how a customer can pick out which wire corresponds to what.
The PX191 Series pressure transducer is a 3 wire voltage output device. Wiring is as follow. Red = + Input Power, White = + Output Signal, Black= Common (- Input Power & - Output Signal

Are the PX191 series sensors suitable for diesel engine fuel pressure monitoring (150psi)? Wetted parts will be in contact with the diesel fuel. My main concern is fire risk if the sensor becomes a heat source.
Thank you for your inquiry, we recommend that you use an intrinsically safe sensor whenever monitoring any media that is flammable.

According to your website power supply requirement is : 5V DC for PX191 Models, 10 to 28V DC for PX192 Models. I have a PX191, 3-wire voltage output of 0.5 - 4.5 V. I'll repeat my earlier question- what is the amount of current required for these.
Becky, thank you for contacting Omega Engineering. Maximum current draw would be 24 mA. You can consider using the PST-4130 power supply. If you have more questions please email pressure@omega.com

What is the maximum resolution of the transducer? We need to measure in resolution of 0.001 torr.
Thank you for you inquiry
This unit will not woirk to .001 torr
please contact the pressure engineers to discuss options that are available.

Several questions - What will the voltage at 1 Torr be and what will the voltage be at 2 Torr? What is the mass of the unit?
The output from the PX190 is 0.5 to 4.5, from zero to full scale. 1 Torr = 0.019337 PSI, the amount of change in the output that you would see from a 75 PS I sensor would be so small we would recommend that you choose a lower range sensor.

A PX-191 appears to require a 5 Vdc excitation voltage. What is the current draw?
Thank you for your inquiry
Power Supply requirement is 10 to 28V DC with the maximum current draw would be 24 mA
Date published: 2021-09-23
Will PX190 work with gas and liquid pressures?
Thank you for your inquiry
Yes the unit has 17-4PH stainless steel wetted parts so as long as the media will work with stainless steel that would be fine.

For the PX191, it says that it needs a 5v power supply. Can that be directly wired into a 5v usb through a computer?
The PX191 Series is a 3-wire device the produces a linear 0.5 to 4.5VDC signal across it's calibrated pressure range. Power requirements are regulated 5VDC with a current draw of 24mA. You cannot communicate via USB with this sensor.
