How To Measure Pressure with Pressure Sensors - NI

26/08/2020· A typical conversion formula will be a function of the excitation voltage, full scale capacity of the sensor, and a calibration factor. For example, a pressure transducer with a full scale capacity of 10,000 PSI and a calibration factor of 3mv/V and given an excitation voltage of 10V DC produces a measured voltage of 15 mV, the measured pressure would be 5000 PSI.

17/05/2021· Excitation voltages lower than the manufacturer’s stated maximum are acceptable for the given load cell. The manufacturer’s recommended value is obviously best, but there is no harm in a lower excitation voltage. For example, 5V is a very common excitation voltage for modern load cells. Modern instrumentation amplifiers are much better than ...

sensor - Is the Excitation Voltage of a load cell a strict ...

I've used pressure sensors from Kulite that have been recommended to run at 10V. I contacted them because I wanted to run at 3V with a precision PSU and they said "no problem" but they weren't prepared to "reduce" what the offset accuracy would be. At 10V they said it's offset was +/-5mV of nominal. Full-scale was +/-100mV and they confirmed that running from 3V would have a full-scale of ...

How does a pressure sensor work? | Omega Engineering

Depending on the strain gauge technology the output can vary from 1 to 3 millivolts per volt (mV/V) to as much as 10 to 30 mV/V. To calculate your full scale output, you would multiply the output of the sensor by the voltage used to power the device. For example, for a 3 mV/V sensor, if we used 10 volts DC as our excitation voltage, we would ...
