Compatible with Proportion-Air electro-pneumatic valves and transducers. The PM-3 is an enhanced-contrast LCD voltmeter. It has been calibrated to provide a direct pressure display from any input or output line from Proportion-Air’s line of Electro-pneumatic regulators and transducers. It is useful as an actual pressure monitor and features low power requirements, extremely long life and easy viewing. The PM-3 employs a dual slope integrating A/D converter and operates from an internal 100 mV reference via a precision DC/DC converter. Measuring only 2.3” x 1.1” x .04”, the PM-3 will fit virtually anywhere. Overall accuracy of 0.5%, automatic changeover, auto-zero and over-range indication, and easy installation means you can upgrade an entire monitoring system. The PM-3 is usually used in pairs, with “command input” and “analog out” signals most frequently monitored.
