Standard base range 10-10,000 PSI (with 1/4" piston option).

Operating pressure range is 0.5 to 20,000 PSI.

Maintain a constant and accurate set point.

Designed for 1% plus or minus repeatability of set points.

Small dead zone between trip and reset pressure.

Use sealed, quick action, dry contact switch, explosion-proof, etc. (UL, Div. 1, Group A, B, C, D).

The spring can be replaced by the sensing pressure present in the instrument and sensor.

If the piston seal leaks, the vent above the sensing piston prevents high pressure from entering the instrument supply.

An optional indicating scale (Model 4E03) may be provided on request.

SIL 3 certified models are available.
