Wiring for an Omega PX191-200GV5 Pressure Sensor on a 43a
Looking for advice on wiring an Omega PX191-200GV5 pressure sensor to a DEWESoft 43a analog port. Voltage is 0 - 4.5v. There is voltage in (RED), Ground (BLACK) and +OUT (GREEN). No other documentation for calibration or scale factors. When I connect it in Single Ended Mode like a P110 sensor from another forum post here on this forum, it shows pressure, however it is starting at -198psi. Do I just Zero it and I am done? Is this accurate? Thank you!

Dear Scott,
the connection is correct, just keep in mind that on the EXC lines you will get +/-5V on Dewe43 and 70 mA. If the sensors require more power switch the power lines of the sensor to pin5 (+12V) and pin4 (GND).
In your case please note that the scaling of the sensor will then need to be corrected since the reference will not be GND but EXC-.
Best Regards.
