Pressure transducers output a raw signal that corresponds to a value in an engineering units. These vaules are usually imprinted on the pressure transducer (i.e. a -15 to 15 PSI operating range with a 0-5V output). The scaling is usually linear, which means you have to use y=mx+b equation for scaling the sensor (m = span, b = offset). You have to find the span and offset (calibration values) using the range limits and output limits. Scale the signal in LabVIEW using the calibration values where "x" is your raw signal and "y" is your usable signal.
