Honeywell Pressuretrol Limit Controller - L4079A1050/U

The Honeywell Pressuretrol Limit Controller is a robust controller geared towards industrial automation. Its operational range spans 10 to 150 psi, and it utilized a Single-Pole Single-Throw (SPST) system that breaks simultaneously on pressure rise. Users can manually reset the operation using an in-built switch, and the system can be easily mounted using a 1/4 in. NPT fitting.

In terms of composition, the controller features a stainless steel diaphragm designed to work efficiently with steam, air, noncombustible gases, and fluids that are non-corrosive to stainless steel. This controller is equipped with micro switch snap-acting switches that open automatically whenever a pressure rise is detected, requiring manual resetting.

The Pressuretrol is designed for mounting convenience to suit various industrial setups. It can be fitted either directly onto the diaphragm assembly via a 1/4 in. NPT female fitting or surface mounted through the base of its case.

On the technical front, this controller is most suitable to regulate and limit control of steam, air, non-combustible gases, or non-corrosive fluids. The electrical connections comprise of secure screw terminals, and the sensor element used within the system is a stainless steel diaphragm. It is designed to work at peak performance even at high operating temperatures, with a maximum threshold of 150F (66C).
