The Honeywell L404F1094 offers operating control with automatic limit protection for pressure systems up to 300 psi (2068 kPa). Suitable for steam, air, non-combustible gases, or fluids non-corrosive to the pressure sensing element. These models feature snap-acting switching to open or close a circuit upon pressure rise, with adjustable differentials modified by screws on the top of the case. Mounting options include 1/4″ to 18″ NPT internal pipe threads or surface mount through the base of the case.
