The 836-C7E Pressure Controller is an industrial electromechanical pressure control switch that has been manufactured by Allen-Bradley/Rockwell Automation. It is intended for general industrial usage in various pressure control systems and it comes with external bellows that are made of copper alloy. This device has been manufactured as a Style C device and it supports enclosures with the Type 7 & 9 and Type 4 & 13 NEMA ratings and that are made of aluminum. It has a pressure specification of 7 and maximum line pressure rating of 300 PSI. Its operating pressure range is 4 to 150 PSI and its differential pressure range is 2.5 to 25 PSI. This device does not support factory modifications such as the standard contact block with double-throw single-pole snap action functions.

The Allen-Bradley 836-C7E Electromechanical Pressure Controller also does not come with the silver contacts that support snap-action functions. It is notable for its straight in-line and relatively friction-free design that helps to provide consistent and accurate operation for an extended period of time regardless of the angle at which this pressure controller is mounted. This device is also engineered to provide easy adjustment of the trip along with reset pressures settings and the operating and differential pressure ratings. The Allen-Bradley 836-C7E Electromechanical Pressure Controller is flexible and utilized in many applications and industries. It is commonly used in controlling the pneumatic and hydraulic systems and also maintenance of the preset system pressures between 2 different values. It is also suitable for use in detecting excessive pressure levels in both liquids and gases, thus helping to protect personnel, application processes, and machines.
