836T-T253E

The Allen-Bradley 836T-T253E controller is an 836 series adjustable pressure controller of the electromechanical variety. The operating range of the controller is 10 to 150 PSI. The maximum line pressure for the 836T-T253E controller, which is the maximum pressure which can be applied without damaging the bellows, is 350 PSI. The adjustable differential pressure rating for the controller, which is the difference between the trip and reset values, is 6 PSI. The 836T-T253E controller has copper alloy bellows. The trip and reset settings on the device are set to their factory defaults when it arrives. The enclosure of the 836T-T253E controller is a Type 7 & 9 and 4 & 13 enclosures and it can be used in hazardous locations. The contact block on the 836T-T253E controller is a 2-circuit contact block. Pressure controls such as those belonging to the Bulletin 836 series from Allen-Bradley can be used to control or monitor an application process or a machine.

The Allen-Bradley 836T-T253E controller helps to control pressure in a system so that it is maintained between the preset high and low values. The controller is used to signal when a preset pressure limit is reached. Controllers from the factory are set to the peak operating rating and the minimum differential rating. The controllers can be adjusted to satisfy any particular pressure-related application. The trip setting on the 836T-T253E controller can be adjusted through a pressure range adjustment screw. However it should be noted that changing the position of the adjustment screw changes the settings for both the trip and reset pressure levels in almost equal increments. The reset setting on the 836T-T253E controller can also be adjusted by rotating the differential adjustment screw, and changing the differential pressure has almost no effect on the trip setting.
