The silicon capacitive pressure sensor PMT16A has excellent accuracy,

repeatability and long-term stability over a wide range of operating

temperatures. Therefore, it maintains its accuracy and calibration for

long periods of time, thus reducing the need for field calibrations.

The fine adjustment and calibration of the sensor at the factory are

handled according to the electronic working standards, which are based

on international standards.
