Honeywell Pressuretrol Limit Controller - L4079B1066/U

Presenting the Pressuretrol Limit Controller, a paramount product from Honeywell with a pressure range of 20 to 300 psi. The device stands out for its Single Pole Single Throw (SPST) functionality which breaks upon pressure rise, and requires manual reset. It features a 1/4 inch National Pipe Thread (NPT) mounting mechanism designed for quick assembly and flexibility.

The Pressuretrol Limit Controller boasts a stainless steel diaphragm suitable for use with steam, air, non-combustible gases, and fluids non-corrosive to stainless steel. This ensures durability, strength, and prolonged service without the risk of wear and tear from harsh industrial environments.

Incorporated in the design are Micro Switch snap-acting switches which open automatically upon a pressure rise and require manual reset. This ensures user safety and maintains a regulated process control.

Users have the option to mount using a 1/4 inch NPT female fitting on the diaphragm assembly or surface mount through the base of the case. This provides versatility and fosters convenient installation tailored to user preferences and operational needs.

The Pressuretrol Limit Controller is specifically engineered to deliver limit control for steam, air, non-combustible gases, and non-corrosive fluids. It employs screw terminals for the electrical connections, reinforcing safe and secure connectivity.

The sensor element, realized in stainless steel diaphragm, ensures efficient sensing capabilities, while maintaining a maximum operational temperature of 66 degrees Celsius (150 degrees Fahrenheit). This guarantees seamless operation even under excessive heat conditions, making the Pressuretrol Limit Controller a standout performer in Honeywell's broad range of industrial automation and control systems.
