You can use this pressure switch from RS PRO in either hydraulic or pneumatic systems. It will supply an electrical signal once the system has reached a pre-set pressure.

You can easily set the switching pressure by turning a screw in the centre of the switch – clockwise to increase the pressure setting and ant-clockwise to decrease it. What's more, it mounts in any orientation. The device is fitted with a mechanical stop to prevent damage from over-pressurisation. It's accurate to within 4% of set pressure, has a DIN (Deutsches Institut für Normung, the German Institute for Standardisation) 43650 electrical connection and fits into a 1/4 in thread. It's also IP65-rated, meaning it's protected from dust and water spray.

Pressure switches such as this one are commonly found in applications including well water pumps, electronic gas compressors and aircraft cabin pressure alarms.
