DESCRIPTION

SPECIFICATIONS

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.

Input

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.

Performance

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.
