1 Sensor Output Characteristics1

The SDP1108-R provides a fully calibrated voltage

output. To enhance the sensitivity at very low

differential pressures, the SDP1108-R comes with a

root-square output characteristic.

1 Calibration conditions apply unless otherwise noted: 23°C and pabsolute = 966 mbar, dry air, VDD = 5.000 V

2 Variance between the zero point (offset) of different sensors measured under the same conditions (e.g. same supply voltage, temperature, …)

3 Include deviations due to linearity, hysteresis, and repeatability

4 % Measured value = (SDP1108-R output [Pa] - output of reference instrument [Pa]) / output of reference instrument [Pa].

5 Full span is defined as 3750 mV / 500 Pa for SDP1108-R

6 Drift over time due to aging, pressure cycles… Test results can be provided.

7 The additional error due to temperature variation is temporary. Once the sensor is back to the calibration temperature, the shift disappears

(no hysteresis).

8 Tau= 0 to 63%, filter response time = 8ms.
