## **RATIOMETRICITY** 

## **SCALING OF 240PC SERIES WITH 8V EXCITATION** 

Ratiometricity refers to the output voltage being directly proportional to supply voltage. 240PC sensors in this catalog are calibrated at 8 VDC supply voltage to provide a 1-6 volt (5 V Span) output swing. For example, if supply increases by 50% to 12 VDC, the output voltage increased by 50% to 1.5-9 volts (7.5 V Span).

NOTE: 241PC sensors are scaled for greater pressure on the P1 side of the chip. 242PC sensors are scaled for greater pressure on the P2 side of the chip. Other scalings available upon request. 

## NOTE 

The output is not perfectly ratiometric. See Accuracy specifications for the degree of error.

## **NULL AND SENSITIVITY TEMPERATURE SHIFT** 

Null and Sensitivity Shift (%Span) 

Amplified pressure sensors are 100% tested to ensure that the maximum null and sensitivity temperature shift does not exceed the specification. The diagram illustrates how null and sensitivity shift relates to temperature. Note that the maximum shift occurs at temperature extremes. Therefore, if a sensor is not exposed 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.

## **NOTES** 

1. Terminals are labeled on the sensor. 

2. Input and output share a common ground. 

3. RL must be greater than or equal to 3000 ohms.
