Add Product to My Catalog

This range has been used to monitor very small changes in vacuums and has been specified extensively for offshore applications.

Incorporating a diaphragm and two sealing Belloframs the switch offers reliable switching action when a differential pressure is required to be sensed. They can, by venting either the HP or LP connection, be used as a low pressure or vacuum switch. Resistors can be incorporated for ‘end of line’ and short circuit monitoring.
