A linear control variable yields a uniform surge margin across the full operating range and simplifies both closed-loop and ...
POPULAR CONTROL: Encapsulated pressure controls are a very popular type of pressure control that can be used on new and existing refrigeration systems. (Courtesy of Joe Marchese) Encapsulated pressure ...
Control valve selection plays a crucial role in optimizing control loop performance, and engineers must consider factors beyond just cost, leakage class and pressure drop. As explored in a Control ...
In 2012, Automation World published an article looking at the decision factors faced when choosing electric or pneumatic actuators. More than a decade later, manufacturing engineers and OEMs still ...
On any type of refrigeration system, from small reach-in coolers all the way to large chillers, controlling the head pressure of the refrigerant is important. That’s because it helps keep the system ...
Pilot pressure can be understood as the pneumatic control signal that defines the setpoint of a regulator. This pilot signal is generated by a separate pilot device in pressure control systems that ...
