836T-T253JX21X9

The Allen-Bradley 836T-T253JX21X9 controller is a Bulletin 836T adjustable electromechanical pressure controller and sensor. The following things should be considered when ordering a Bulletin 836T pressure controller: the device style, pressure connection hardware, enclosure type, pressure media, occasional surge pressure, and the adjustable differential and operating pressure ranges. The 836T-T253JX21X9 controller is a Style T controller with bellows made from copper alloy. The enclosure of the 836T-T253JX21X9 controller is designed for industrial use and it is a NEMA Type 1, 4, and 13 enclosure. The 836T-T253JX21X9 controller has 2 circuits on the contact block. The pressure ratings for the 836T-T253JX21X9 controller include an occasional surge pressure rating of 450 PSI maximum, a line pressure rating of 350 PSI maximum, an adjustable operating pressure rating range from 12 to 150 PSI, and an adjustable differential pressure rating range from 6 to 30 PSI.

The bellows on the 836T-T253JX21X9 controller are specially prepared for nitrous oxide and oxygen service. The 836T-T253JX21X9 controller has been tested with pure oxygen. The bellows on the control are plugged for protection from contamination and a tag warning for contamination is also applied. Bulletin 836T controllers such as the 836T-T253JX21X9 controller are suitable for applications such as coolant pressures, air compressors, lubricant pressures, machine hydraulic pressures, and machine tools applications. The operating temperature range for the 836T-T253JX21X9 controller is -22 to 150 degrees Fahrenheit. In storage, the controller should be kept in an area where the ambient temperature is kept between -22 and 200 degrees Fahrenheit. To prevent electric shock, the 836T-T253JX21X9 controller and associated equipment should be disconnected from the power source before installation or servicing. Controllers like this one are supplied with a removable paint mask which should be removed on final installation.
