Product Description

The Honeywell L404F1102 is a PressureTrol® controller designed for use in steam, air, non-combustible gases, or non-corrosive fluid applications. This model provides operating control with automatic limit protection for pressure systems up to 300 psi (2070 kPa). It features a snap-acting switch that opens or closes a circuit on pressure rise, with adjustable differentials for precise control. The unit is equipped with a stainless steel diaphragm as the sensing element and offers a differential pressure range of 10 to 22 psi (69 to 152 kPa). Adjustments are made via screws on top of the case, and mounting can be done using 1/4"-18 NPT internal pipe threads or surface mounting through the base of the case.
