CVG101 Convection-Enhanced Pirani Gauge

The CVG101 Worker BeeTM 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.​
