CVM211 Convection-Enhanced Pirani Gauge
CVM211 Stinger is the most basic convection enhanced Pirani vacuum gauge module with a built-in controller, display and process control signal.
The pressure measurement range of the CVM211 is 1.00E-04 to 1,000 Torr.
CVM211 is available with various fittings including 1/8 in. NPT male, 1/2 in. O.D. Tube (O-ring compression), NW16KF, NW25KF, NW40KF, 1/4 in. Cajon 4VCR, 1/2 in. Cajon 8VCR, 1 1/3 in. Mini-Conflat and 2 3/4 in. Conflat.
Additional information
The sensor inside the CVM211 StingerTM module 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.
