PF266 Titan Ultra Low Pressure Switch

Brand: Pyropress Engineering Company Limited
This range has been used to monitor extremely small changes in pressure and has been specified extensively for offshore applications.

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