The 836T-T251JX23X9 pressure controller is a pressure condition sensing device from the 836 series, specifically the Style T product. This controller has been made by Allen-Bradley and is versatile enough to work within multiple applications. It has been designed to operate in applications with pneumatic and hydraulic devices. This pressure sensor and controller measures the pressure levels in these systems. One of its objectives besides controlling pressure is to prevent damages by performing a tripping action to guarantee safe operations. The Allen-Bradley 836T-T251JX23X9 pressure sensor and controller comes with internal copper alloy bellows and with a Type 1, 4, and 13 enclosure. This enclosure protects the device from different solid particles that might enter the enclosure, but it does not support operations with corrosive materials. 

The Allen-Bradley 836T-T251JX23X9 pressure sensor and controller can come into frequent contact with different fluids such as air, non-corrosive gases, water, and non-corrosive liquids. The Allen-Bradley 836T-T251JX23X9 pressure sensor and controller comes with an adjustable operating pressure range of 30 inches of mercury in a vacuum to 35 PSI and an adjustable differential pressure range of 2 to 7 PSI. Both of these pressure ranges can be manually adjusted by turning the corresponding adjustment screws. The Allen-Bradley 836T-T251JX23X9 pressure sensor and controller has a maximum line pressure rating of 80 PSI and a maximum occasional surge pressure rating of 90 PSI. This device supports a LED pilot light that is required by some applications. This device also comes equipped with 2 contacts and it uses a quarter-inch NPTF female connector.
