Fischer ME12 ATEX – Compact Digital Pressure Transmitter – Zone 2

Working Principle:

The measuring pressure is applied directly on ceramic diaphragm, which cause distortion. This distortion alters resistance of strain gauge on the rear side of the diaphragm, in proportion of the level of distortion.
Electronic module of the pressure transmitter converts change in resistance to proportional standard electrical signals.

To optimise performance inline with operating process conditions, the instrument can be configured on-site via PC programming adaptor EU13.
