PM-4 Panel Meter

Proportion-Air’s electronic pressure control valves are all closed-loop around some type of sensor. Often, this is an internal pressure sensor inside the control valve.

This sensor signal is used by the valve to close the loop and is then transmitted out as an analog monitor signal.

Often, users would like to have an easy method of observing what the value being controlled by the valve is.

Reading the analog monitor signal directly on an LED or LCD panel meter is a common method of allowing a quick visual reference to see what value the Proportion-Air control valve is holding to.
