Gauge Pressure Switch P20M Series

The P20M features an incredibly low pressure setting range despite its small size. The polyimide diaphragm sensor provides both long life and media resistance for many liquid and gas applications. Aircraft fuels, lubricating oils and engine bleed air are common media that the P20M monitors and controls. A negative rate Belleville spring is standard on every unit to meet the harsh environments encountered in military vehicle and commercial aircraft applications. Hermetically sealed electrical switches are commonly supplied to ensure resistance to sand, dust, icing, humidity and salt fog.

• Negative-rate belleville spring design for longer life, accuracy and repeatability
