Differential pressure switch for compressor

摘要

A first part (1) moves between two positions when a differential pressure exceeds a certain pressure. A second part (2) controls the pressure system (e.g. a compressor) based on the position of the first part. The first and second parts border on each other directly. A magnetic coupling (3a,3b) is used to transfer the changes in position from the first part to the second part. A delay device may be included, in the form of a resistance heating element and a bimetallic strip.
