Request Information Favorite
This range has been used to monitor filter blockage and air movement through ducting and has been specified extensively for offshore applications.

 Incorporating a diaphragm and two sealing Belloframs when vacuum is required to be sensed the switch offers reliable switching action. Resistors can be incorporated for ‘end of line’ and short circuit monitoring.
