Other pressure ranges are available on request. Please contact Sensortechnics.
Specification notes:
1.
Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters
of the sensing element.
2.
Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to
the housing.
3.
Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure.
4.
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.
5.
Extended temperature ranges on request. Please contact Sensortechnics.
6.
Max. delay time between pressure change at the pressure die and signal change at the output.
7.
The response time depends on the adjusted internal A/D resolution of the sensor. For 12 bit it is typ. 0.5 ms. Other A/D resolutions
and reponse time are available on request. Please contact Sensortechnics for further information.
8.
Sensors with lower current consumption are available on request. Please contact Sensortechnics for further information.
