The Allen-Bradley 836T-D453J Electromechanical Differential Pressure Controller is a pneumatic pressure control device from the 836 Pressure Controls series that is specifically designed and manufactured by Allen-Bradley for the measurement and control of the pressure differential between the 2 pressure levels at the 2 different pressure inputs on the controller. Once this pressure differential reaches a certain point (known as the setpoint), the instrument will automatically trigger a set of electrical contacts that are SPDT (Single-Pole, Double-Throw) contacts, enabling the connected electrical circuit to perform a control action on the measured variable. The Allen-Bradley 836T-D453J Electromechanical Differential Pressure Controller is able to meet user application demands during a long operating life, because of its heavy-duty construction that includes an oil-tight, metal casing that is able to protect the internal mechanisms of the controller in different kinds of harsh industrial environments.

The Allen-Bradley 836 series 836T-D453J Electromechanical Differential Pressure Controller has a configurable differential pressure range of 10 to 50 PSI, with a maximum rated pressure difference between its inputs of 70 PSI. This controller is often employed for sensing pressure differentials in various machine tools applications, as well as in industrial plant floor applications including indirect level control applications or flow measurement and control applications. The Allen-Bradley 836T-D453J Electromechanical Differential Pressure Controller can be mounted in both vertical and horizontal positions for outdoor or indoor applications. The maximum operating voltage compatible with the electrical contacts of this instrument is 600 Volts AC, and the maximum inrush current rating is 5 Amps. The environmental operating temperature of the location where the device is going to be installed should be kept within the range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).
