Pressure transducer is a device that converts input pressure into electrical output signal. The pressure drop [kPa] across a valve in a water pumping system
Pressure transducer is a device that converts input pressure into electrical output signal. The pressure drop [kPa] across a valve in a water pumping system was measure with a pressure transducer that provides a voltage signal [mV].
The results are in the picture.
a) Based on the calibration measurement results, form a linear model U= K*p+a for the pressure p to voltage U relationship of the pressure transducer. Create a straight model in units [kPa] and [mV].
Also determine the transducer nonlinearity (in millivolts) when the transducer pressure is 25 kPa and the output signal is 163 mV.
b) Find nonlinearity at 25 kPa as a percentage of span.
