Specification notes:

1.

Total accuracy is the combined error from offset and span calibration, linearity, pressure hysteresis, and temperature effects.

Linearity is the measured deviation based on a straight line. Hysteresis is the maximum output difference at any point within

the operating pressure range for increasing and decreasing pressure. Calibration errors include the deviation of offset and

full scale from nominal values.

2.

Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure.

3.

Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters

of the sensing element.

4.

Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to

the housing.

5.

The HCE common mode pressure is 2 bar for all devices up to 500 mbar and 7 bar for all other devices. Common mode

pressure is the maximum pressure that can be applied to both ports of a differential pressure sensor simultaneously without

damaging the sensor housing.

6.

Extended temperature ranges on request. Please contact First Sensor.

7.

Max. delay time between pressure change at the pressure die and signal change at the output.

8.

The response time depends on the adjusted internal A/D resolution of the sensor. For 14 bit it is typ. 1 ms. Other A/D resolutions

and reponse times are available on request. Please contact First Sensor for further information.

9.

Sensors with lower current consumption are available on request. Please contact First Sensor for further information.

Other pressure ranges are available on request. Please contact First Sensor.
