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. Max. delay time between pressure change at the pressure die and signal change at the output.
6. The response time depends on the adjusted internal A/D resolution of the sensor. For 15 bit it is typ. 2 ms. Other A/D
resolutions and reponse times are available on request. Please contact Sensortechnics for further information.
7. Sensors with lower current consumption are available on request. Please contact Sensortechnics for further information.
