Provide operating control with automatic limit protection for pressure systems up to 300 psi (2068 kPa).

Features

• Use with steam, air, noncombustible gases, or fluids non-corrosive to pressure sensing element.
• Models have snap-acting switching to open or close a circuit on pressure rise.
• Have adjustable differentials.
• Adjustments are made by screws on top of case.
• Mount using 1/4 inch -18 NPT internal pipe threads or surface mount through base of case.
• Ground screw terminal.
