Honeywell Pressuretrol Limit Controller - L4079B1033/U

The Honeywell Pressuretrol Limit Controller is designed to regulate steam, air, noncombustible gases, and non-corrosive fluids in a pressure range of 2 to 15 psi. Despite pressure elevations, it maintains consistent performance with its SPST break on pressure rise feature. To ensure playful safety after system abnormalities or pressure surges, this controller requires manual reset switch operation.

Its diaphragm, which is made of high-quality stainless steel, enhances the controller's longevity in multiple environments. It also equips the controller with robust resistance against corrosion, especially when interacting with steam, noncombustible gases, air, and several non-corrosive fluids.

Adding to its safety and reliability features is the microswitch snap-acting mechanism. This feature allows the switches to open automatically when the pressure mounts, although manual resetting is a prerequisite for reactivating the system. The convenient mounting options include a 1/4 inch NPT female fitting integrated into the diaphragm assembly, or mounting through a surface on the base of the case.

The controller facilitates seamless installation with its easy-to-access screw terminals for electrical connections. It is designed to work safely and efficiently at a maximum operating temperature of 150 degrees Fahrenheit (66 degrees Celsius). Enhanced with all these versatile features, this Honeywell controller ensures streamlined control over your industrial automation requirements.
