Performance characteristics – metal diaphragm
Reference accuracy Reference accuracy comprises non-linearity after limit point setting, hysteresis and non-reproducibility as per
IEC 60770.
Note!
In the case of overpressure measurement using absolute pressure sensors, the accuracy can be affected by
fluctuating ambient air pressure.
Thermal change of the zero
output and the output span
4...20 mA
4...20 mA HART, PROFIBUS PA
!
Note!
When using a PMP46/48, the influence of the respective diaphragm seal must also be taken into account.
(→ See also Page 59 ff "Planning instructions for diaphragm seal systems", Page 45 ff "Process connections
PMP46 (with metal measuring diaphragm)" and Page 51 ff "Process connections PMP48 (with metal measuring
diaphragm)").
Temperature coefficient (T
K
)
for zero output and output
span
If the value for the temperature coefficient exceeds the value for the thermal change, the thermal change
automatically applies.
