Differential Pressure Control - an overview ...

Apart from this temperature control, there is another automatic control loop that is unique to ball-tube mills. The differential pressure across the mill is maintained at a constant pressure to ensure enough raw feed storage capacity inside the mill. The automatic DP control loop is discussed in Clause 5.3.2 of this chapter. 2.3.4.3.2 Feeders

Differential pressure controllers in the primary system are mainly used to keep a constant and lower differential pressure across a motorized control valve or a total system/substation. As a rule of thumb, the differential pressure controller should be used whenever the ratio between maximum and minimum available differential pressure from the network is larger than 2.

Differential Pressure Controls | McMaster-Carr

These switches operate based on the difference in pressure between two process lines. When the differential pressure exceeds your setpoint, the switch is activated. Often used to indicate clogged filters, they are designed to automate controls or activate an alarm in your process. Switches are single pole, double throw (SPDT), so they switch one circuit on or off.
