The InstruTech CVG101 Sensor
The CVG101 Worker Bee™ convection vacuum gauge sensor
incorporates numerous design enhancements compared to
other traditional convection vacuum gauges.
Temperature compensation has been moved out of the
vacuum environment and placed around the outside of the
vacuum gauge tube. This has eliminated a dozen or so
unnecessary parts and welds, significantly increasing the
reliability, providing optimal vacuum measurement while
reducing cost. The improved mechanical strength results in
a highly robust vacuum gauge less susceptible to mechanical
shock and vibration.

Other design features include reduced internal volume and
significant reduction of internal surface area resulting in faster
pump-down and less outgassing. A fine mesh screen in the gauge
inlet port helps prevent particulate contamination from entering
the gauge. The gauge is shielded against RF interference.
These, and other, design features add up to a highly reliable
vacuum gauge with significant cost savings that are passed on to
the user.

Upgrade for thermocouple TC vacuum gauges
The CVG101 Worker Bee provides a wider measuring range
than traditional thermocouple vacuum gauges - from
1 x 10-4 Torr to above atmosphere - so you can monitor your
entire pump- down and vent cycle.

The CVG101 Worker Bee convection enhanced Pirani gauge is more
accurate than a thermocouple gauge, especially at lower pressures.

Also a Low cost drop-in replacement for the Convectron® Gauge
The CVG101 Worker Bee can also directly replace the
Granville-Phillips® Convectron® sensor, at significantly lower
cost.
The InstruTech CVG101 Worker Bee convection vacuum
gauge provides equivalent or better performance
throughout the range of 1 x 10-4 to 1,000 Torr. Only the
same, equivalent, or better materials are used in the
vacuum environment. Clean assembly procedures assure
compatibility with today's contamination-sensitive
processes. All tooling that comes in contact with vacuum
surfaces of the InstruTech gauge are of very low vapor
pressure materials.

The sensor connector has the same pinouts and signal as the
corresponding Convectron®. It is directly interchangeable with
your existing Convectron® controllers, cables, so you don't need to
change any wiring, hardware, or process recipes. With Worker
Bee’s performance, more robust design, longevity, and lower cost,
your process will only improve.
Guided by our vast experience and vacuum measurement know
how, InstruTech sensors are specifically designed for optimum
reliability and performance. Whether you're looking to reduce
costs or improve your process, the CVG101 Worker Bee offers a
cost-effective solution for your vacuum gauging needs.
