L404F1060/U锅炉压力控制开关

L404F1060/U
Overview
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.
