Honeywell L91B1118 Proportional Pressuretrol Controller 10-300 PSI

The Honeywell L91B1118 Prop Pressuretrol is a pressure control switch specifically designed for maintaining consistent pressure within HVAC systems, typically between 10 and 300 psi. It senses pressure and uses that information to turn equipment on or off, much like a switch.This is how it operates: The diaphragm used in the L91B1118 expands or contracts in response to system pressure. Compressors, pumps, and valves are among the associated equipment that receive an electrical signal from the diaphragm to turn on or off when the pressure exceeds a predetermined threshold. The pressure control points can be adjusted thanks to its adjustable differential range.A lot household and commercial HVAC systems, such as boilers, air conditioners, and oil and gas furnaces, frequently use this pressure control.
