PROCESS MEASURING INSTRUMENT

摘要

The process measuring instrument comprises a sensor which may be fitted in the wall of a vessel containing a process medium and an electronics housing, mechanically coupled to the sensor, for the measuring instrument electronics. The electronics housing is at least temporarily subjected to vibrations generated by the sensor during operation, or transmitted by the sensor. In order to reduce the amplitude of oscillations for said vibrations of the electronics housing, at last one vibration damper is fixed to the wall of the electronics housing, which is at least temporarily set in oscillation to dissipate the oscillation energy transmitted to the electronics housing. The noise fraction in the measured signal can be reduced by the suppression of such housing vibrations such that a significant improvement in the signal to noise ratio in the measured signal can be detected.
