Bellows pressure switch 5-1780-0

absolutethreadedBSP 1/4

This density switch is characterized by an element sensible to pressure which is placed in contact to the gas section of the circuit to be monitored, It is composed of one below rigidly connected to a second below exposed to atmosphere pressure. The two micro-switches of the device are positioned between the two elements sensible to pressure. Placing the sensible element in contact to atmospheric pressure renders the device insensitive to variation of both temperature and environment pressure, allowing the reading of the switching pressures at absolute level.
