Designed for pressure quench heat treat furnaces, this Diaphragm Vacuum and Pressure Gauge covers the entire range
from 30 inches Hg vacuum to 150 PSIG.

The instrument includes 6 independent set points which are
adjustable over the entire range and each set point drives a separate relay. Each of the six relays has SPDT contacts rated for 3 amps @ 115 or 220 VAC non-inductive.

In addition to the six on/off outputs, this gauge also provides a
linear analog output for interface with PLCs, P.C.s, or recorders.
This output is negative 300 millivolts at 30 in. Hg to zero at
atmosphere to 1.5 volts at 150 PSIG (10 mV/PSIG). Unlike
thermal or ionization type gauges these instruments are not
affected by changes in gas composition. Enclosures are available
for transducers located in hazardous areas including Class I,
Groups C and D, Division 1.
