Proportional Control

Clippard, Cincinnati, OH, has released a new high-press proportional control that provides a pressure range of 0–500 psig. The Cordis HP500 uses a microcontroller, integrated pressure sensor, and two electronic valves. The inlet valve is connected to the moderately regulated supply pressure, and the exhaust valve is connected to a port that vents excess pressure to atmosphere. Once a command is increased, the inlet valve opens up to allow supply pressure to pass over the sensor element, which provides an active feedback for the microcontroller to satisfy the set point in the process. If at any point the sensor detects a value higher than the set point, the exhaust valve will modulate open to vent off the excess pressure.
