The Allen-Bradley 836-C3E Pressure Controller is a standard pressure control unit from the Bulletin 836 pressure control family, and it is designed to detect, monitor, and control operating pressure conditions in many types of pneumatic or hydraulic applications. The 836-C3E Pressure Controller is suitable for applications in air compressors, liquid level control, high and low-pressure alerts, vacuum transfer systems, and compressed air monitor systems. Overall, the Bulletin 836 pressure control series improves application processes and systems, protects expensive equipment, and helps safeguard the operators. The 836-C3E Pressure Controller features a very compact design and high-quality components that help provide long-lasting use in applications that involve water, air, non-corrosive gases, and some corrosive liquids/gasses.

The 836-C3E Pressure Controller features adjustable pressure trip and reset settings. Users can adjust the operation pressure range from 30 inHg up to 10 PSI and differential range from 0.4 to 6.0 PSI. The 836-C3E Pressure Controller has both operation range and differential adjustment screws with trip indicating scales (both metric and PSI) on the front side of the device. To adjust the trip setting, the users can turn the operating range adjustment screw either clockwise or counterclockwise to raise or lower the pressure trip setting, and users can also set the reset trip by adjusting the differential adjustment screw clockwise or counterclockwise direction to raise or lower the differential. The 836-C3E Pressure Controller is supplied with standard snap-action contacts that can be wired to close or open with decreasing or increasing pressure conditions. The 836-C3E Pressure Controller has a repeat accuracy value of -/+0.5% and it comes in an aluminum enclosure with NEMA Type 4 and 7, 9 and 13 combined enclosure ratings.
