Performance characteristics – ceramic diaphragm
Reference accuracy Reference accuracy comprises non-linearity after limit point setting, hysteresis and non-reproducibility as per
IEC 60770.
PMC41, PMC45:
Note!
In the case of overpressure measurement using absolute pressure sensors, the accuracy can be affected by
fluctuating ambient air pressure.

If the value for the temperature coefficient exceeds the value for the thermal change, the thermal change
automatically applies.
