Honeywell L91D1031 Pressuretrol Controller 5-150 PSI Proportional Control 2-135@ Potentiometers

The Honeywell L91D1031 5/150 Prop.-Trol,2-135 For use with steam, air, non-flammable gas, and other non-corrosive fluids, Pots is a proportional pressure control switch. It controls the pressure inside a system by varying the electrical resistance in accordance to the pressure that is sensed. This means that rather than turning on or off at predetermined pressure points, the switch gradually adjusts, giving you more exact control.With a dual potentiometer that has a resistance of 135 ohms each, this switch can work in the pressure range of 5 to 150 pounds per square inch (psi). Adjusting the pressure control settings is made possible by these potentiometers.Honeywell thermostats, specifically models L91D1031, L91D1032, and L91D1033, are commonly utilized in conjunction with the Honeywell L91D1031. Pressure regulation affects operations such as burner operation in an indirect manner.
