Pneumatic threshold sensor

This pneumatic threshold sensor monitors system pressure and provides a signal when a set point is reached. It features a female NPT inlet sized at 1/8 in and a tube connection for 5/32 in tubing. The body uses polymer construction with NBR seals. It is a new component supplied under the Legris 7808 04 11 part number.

Suitable for pressure monitoring

This unit suits pneumatic circuits that operate between 43.5 psi and 116 psi and within a temperature range of 5 Degrees F to 140 Degrees F. It is not for hydraulic systems or applications exceeding the stated pressure and temperature limits. Buyers needing different port sizes, thread types or seal materials should look at alternative components.

Pressure operating window

The decisive specification is the operating pressure window of 43.5 psi minimum to 116 psi maximum. If the circuit pressure falls outside this range the sensor will not function as intended.

Questions about this item

At what pressure does the 7808 sensor stop switching reliably during continuous operation?

The sensor operates between 43.5 psi minimum and 116 psi maximum; sustained pressure above 116 psi exceeds its rated limit.

How much heat can the polymer body and NBR seals of the 7808 withstand when the line runs all day?

Maximum operating temperature is 140 °F; the polymer body and NBR seals are rated for continuous use up to that temperature.

Which fittings must I already have to connect the 1/8 in NPT female inlet and 5/32 in tube outlet on the 7808?

You need a 1/8 in NPT male fitting for the inlet and a 5/32 in (4 mm) push-to-connect tube fitting for the outlet.
