Air Logic Pneumatic Components and Systems F-4103 Series Diaphragm Comparator details.

The Diaphragm Comparator is a versatile control circuit component for both fluidic and pneumatic signal levels. It performs many functions including those of an analog pressure comparator, an analog pressure repeater and a digital signal isolator.

There are two ports on one side of the diaphragm, a center leak-port with a 0.020" diameter and an input port. A dead-ended inport port supplies pressure to the opposite side of the diaphragm.
