Total 3D linearisation of DP transmitters
Maintaining safe process conditions with active compensation of varying operating conditions in real processes
Once commissioned, differential pressure transmitters usually need to be readjusted at regular intervals to ensure long-term stable measurement under changing process conditions.
During factory calibration, the KROHNE DP transmitters are 3D linearised in all three dimensions – differential pressure, ambient temperature and static pressure – ensuring a long-term, stable, robust and accurate differential pressure measurement under all process conditions.
Increased safety, reliability and long-term stability due to total 3D linearisation
3D linearised DP transmitters consider differential pressure, DP sensor temperature and static pressure in all combinations
Impact of fluctuating conditions on measurement uncertainty minimised
OPTIBAR DP transmitters with integrated absolute pressure sensor and full 3D linearisation cause no drift even with frequently changing line pressures
Time-consuming calibrations for commissioning are reduced, no regular readjustments needed
Extended intervals for recalibration reduce operating costs in the long run
