NULL COMP, e RATIOMETRICITY OUTPUT VOLTS VS" 16Vs FSO*10V VS= 12Vy FSO*7.5V VS= 85 Ratiometricity refers to the output voltage being directly proportional to the supply voltage. 140PC sensors in this catalog are calibrated at 8 VDC supply voltage to pro- vide a 1-6 volt (5V Span) output swing. For example, if supply increases by 50% to 12 VDC, the output voltage increases by 50% to 1.5-9 volts (7.5 V Span). NOTE The output is not perfectly ratiometric. See specifications for the degree of error. NULL AND SENSITIVITY TEMPERATURE SHIFT Amplified pressure sensors are 100% tested to insure that the maximum null and sensitivity temperature shift does not exceed the specification. The diagram below illustrates how null and sensitivity shift relates to temperature. Note that the maximum shift occurs at temperature ex- tremes. Therefore, if a sensor is not ex- 140PC Series posed to the entire temperature range, the maximum null and sensitivity shift will actually be less than the value specified. This diagram indicates the temperature shift pertaining to a few listings. Maximum null and sensitivity shift varies from listing to listing.
