Gauge
Temperature compensation has been moved out of the vacuum environment, significantly reducing costs and improving performance.
The gauge is shielded against RF interference. A fine mesh screen in the gauge inlet port helps prevent particulate contamination from
entering the gauge. changes were made to improve mechanical strength, resulting in a more robust gauge less susceptible to mechani-
cal shock and vibration. Guided by our years of experience manufacturing these gauges, our CVG sensor was designed to be more repro-
ducible and easier to make.
The CVM-211 "Stinger"
InstruTech's CVM Series modules add the necessary signal conditioning electronics to turn the CVG gauge into a vacuum measuring
instrument. The CVM-211 "Stinger" module provides a standard non-linear analog output, and one setpoint relay. In addition, a built-in
LED display gives the user a convenient interface for setup and operation of the vacuum gauge.
Directly drop-in replacement for GP Mini-Convectron modules
The Stinger can directly replace the most basic Granville-Phillips Mini-Convectron modules, at significantly lower cost. the 9-pin D con-
nector has the same pinouts and signals as the corresponding Mini-Convectrons. The non-linear analog signal and setpoint relay config-
uration are identical to their corresponding Mini-Convectron functions. Except for the Stinger's smaller size and lower cost, you and your
process will never know the difference.
Low cost upgrade for thermocouple TC vacuum gauges
The Stinger provides a wider measuring range than traditional thermocouple vacuum gauges - from 10
-4
Torr to atmosphere - so you
can monitor your entire pumpdown and vent cycle. Convection -Pirani gauges are more accurate than thermocouple gauges, especially
at lower pressures. And depending on your gauge/readout configuration, the cost of a Stinger is about the same, or very little more, than
the cost of a TC gauge system.
