The Allen-Bradley 836T-D452JX81X9 Electromechanical Differential Pressure Controller is a tough and durable pressure control device that opens and closes an electrical circuit when a certain differential pressure level is reached between the pressure signals connected to its input ports. This type of differential pressure switch commonly controls industrial application processes where the operation set points can be maintained by turning bi-stable actuators on and off or starting and stopping motors. Some of the common applications of the Allen-Bradley 836T-D452JX81X9 Electromechanical Differential Pressure Controller include opening or closing a control valve to maintain the desired level of a liquid inside a tank, triggering the start of a pump to increase the flow of water through a given section of pipe in a system, or controlling the pressure applied by a hydraulic cylinder.

The Allen-Bradley 836T-D452JX81X9 Electromechanical Differential Pressure Controller is simple to configure by the final users, who can configure it by using the operating pressure range adjustment screw and the differential pressure range adjustment screw. Additional options like a pilot light that indicates if the switch is triggered are also available. The Allen-Bradley 836T-D452JX81X9 Electromechanical Differential Pressure Controller is calibrated in the factory using state-of-the-art calibration tools and procedures in order to guarantee an accurate control of any process where their switches are deployed. This controller comes with a pair of copper alloy bellows that are specifically designed to be used in harsh industrial environments (but not in corrosive ones). The maximum voltage that can be applied to the electrical contacts is 600 Volts AC, and the maximum current rating of 5 Amps.
