Precision Sensors’ P-M Series gauge pressure switches are the most popular products in the Precision Sensors product line and are used in hundreds of applications. The series consists of the P12M, P18M, P20M, and P56M switches. The polyimide diaphragm design offers extreme service life while maintaining high repeatability and a wide operating temperature range. The negative-rate Belleville spring design is well-suited for demanding aerospace and automotive applications. The hermetically sealed electrical switch is ideal where there is a risk of vapor ignition.
The most common applications include fuel and hydraulic oil pressure, engine air bleed systems and fan static pressure.
Key features include:
- Designed for liquid or gaseous media.
- Media-contacting materials: 300 CRES, aluminum, polyimide, elastomer seal (varies by media).
- Hermetically sealed contacts.
- Proven negative-rate Belleville spring design for long service life and repeatability.
