Pressure signal trimming

Calibrating a Rosemount
to adjust for mounting effects.
Sensor trimming requires an accurate pressure input and adds additional compensation
that adjusts the position of the factory trim to optimize performance over a specific
pressure range.
Note
Sensor trimming adjusts the position of the factory trim. It is possible to degrade the
performance of the gauge if the trim is done improperly or with inaccurate equipment.
Absolute pressure devices are calibrated at the factory. Trimming adjusts the position
of the factory characterization curve. It is possible to degrade performance of the
device if any trim is done improperly or with inaccurate equipment.
