Gauge Pressure Switch P18M Series

The P18M design, which features a polyimide pressure sensor, offers increased sensitivity in the lower pressure ranges typically encountered in engine bleed air and fuel pressure applications. Polyimide sensors have incredible cycle life, outstanding temperature performance and wide media compatibility. A negative rate Belleville spring is utilized to ensure stable set points over the life of the unit even during severe shock and vibration. Housings are available in both aluminum and stainless steel depending on weight and fitting requirements.
