Redwood Microsystems MicroPR
The Redwood Microsystems MicroPR is a gas pressure regulator based upon the microvalves developed by Redwood Microsystems. The operating principle is the same as for the MicroFR, except that a) there is no flow restrictor in the flow path, b) there is only a single pressure sensor, and c) feedback control uses the pressure reading, not the flow reading, compared against a setpoint.
These are legacy devices: once the inventory is exhausted, no new devices will be available (unless of course someone wishes to invest in the redeployment of their manufacture...)
