The 836T-T350J pressure controller is a T-style industrial pressure controller from Allen-Bradley/Rockwell Automation. It has been manufactured in the 836T pressure controller product line which is part of the Allen-Bradley 836 Pressure Controls series. The 836T-T350J pressure controller is protected by an enclosure with a Type 1, 4, and 13 protection rating. It also has a contact block with 2 circuits. This controller can control 2 different pressure ranges which are the adjustable operating pressure range and the adjustable differential pressure range. The 836T-T350J pressure controller is set at the highest possible operating pressure range and at the lowest possible differential pressure range at the factory, and the users can change these settings according to the needs of their applications. The adjustable operating pressure range is from 80 PSI to 550 PSI while the adjustable differential pressure range is from 60 PSI to 75 PSI.

The Allen-Bradley/Rockwell Automation 836T-T350J T-style industrial pressure controller from the Allen-Bradley 836 series is equipped to tolerate an occasional surge pressure level of up to 5000 PSI. However, it is not equipped to handle such a high pressure level on a regular basis and prolonged operating under such high-pressure conditions can cause controller damage, erratic operation, user injury, and even explosions. The 836T-T350J pressure controller can be ordered with factory modifications for special applications. One of the available modifications is a special diaphragm with a 0-ring assembly. The 0-ring is made of Viton and the diaphragm is made of Nomex and Viton, and these accessories are required when the 836T-T350J pressure controller is being used in applications that involve phosphate esterbase or similarly adverse hydraulic fluids.
