Rated 4 out of 5 by from Great sensor, details are lacking. Like the design, but the termination and artificially stiff backer rod in the cable are both sub-par.

Will PX190 work with gas and liquid pressures?

Asked by: manu
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 (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.

Asked by: LewisCJ
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.

Asked by: APEDE
Thank you for your inquiry, we recommend that you use an intrinsically safe sensor whenever monitoring any media that is flammable.

What is meant by cable connection? Cannot find information on what the end looks like. Need it to know what it is for data acquisition device and power supply

Asked by: corycharter
The PX190 Series unit have a 19" cable permanently attached. The cable has bare wire connections at the end. This is a 2 wire loop powered device.

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.

Asked by: becky
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

I am trying to connect the PX912 (4-20mA) to a Danfoss VDF (VLT Aqua Drive) with no success. The application exaple for the VDF shows a 2-wire transducer, but this is a 3-wire... what should the connection look like?

Asked by: JPP1982
PX192 is a 2-wire 4 to 20mA device. You would only use the RED (+) and BLACK (-) leads. The GREEN is only used on the PX191 which is a 3-wire Voltage output device

What is the maximum resolution of the transducer? We need to measure in resolution of 0.001 torr.

Asked by: Nadav
Thank you for you inquiry This unit will not woirk to .001 torr please contact the pressure engineers to discuss options that are available.
