The Allen-Bradley 836-C8J electromechanical pressure controller is manufactured as part of the Bulletin 836 Pressure Controls product line. It has been engineered for industrial usage, and it is particularly designed for detecting and controlling pressure in pneumatic pressure systems and in hydraulic pressure systems. This pressure controller comes is a Style C 836 pressure controller with external bellows made of copper alloy and it has a pressure specification of 8 with support for a protective enclosure that is a Type 4 and 13 enclosure made of aluminum. The Bulletin 836 Pressure Control devices like the Allen-Bradley 836-C8J pressure controller are used in the hydraulic and pneumatic industrial pressure systems that do not involve corrosive substances. Exposure to corrosive substances will damage the 836-C8J pressure controller’s copper alloy bellows. It has a durable design and rugged components that provide long-term and reliable operation with pressure systems that use water, oil, and air, as well as most types of non-corrosive gases, vapors, and liquids. 

Among the main components of the Allen-Bradley 836 series 836-C8J electromechanical pressure controller are a contact block, an external bellows connection, an operating pressure range adjustment screw, a differential pressure range adjustment screw, and a differential reference scale. The adjustable operating pressure range runs from 6 PSI to 250 PSI while the adjustable differential pressure range runs from 4 PSI to 45 PSI. It also features a mounting bracket, along with a trip indicating scale, a nameplate with pressure and the external rating information, and a clear contact inspection cover. However, the Allen-Bradley 836-C8J pressure controller does not support any factory modifications for special applications.
