The document describes the InstruTech CVM211 StingerTM Connection Vacuum Gauge Measurement Unit & Display. It has the following key points: - It has a wide measurement range from 1.0 x 10-4 to 1000 Torr and can monitor vacuum systems from atmosphere to high vacuum. - It has a built-in digital display, analog output, and setpoint relay for easy setup and operation. It provides more accurate measurements than thermocouple gauges, especially at lower pressures. - It can serve as a lower-cost, drop-in replacement for basic Granville-Phillips Mini-Convectron models, providing equivalent or better performance with significant cost savings.

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. The CVM211 Stinger provides a wider measuring range than traditional thermocouple vacuum gauges - from 10-4 Torr to above atmosphere - so you can monitor your entire pump- down and vent cycle. The CVM211 Stinger convection enhanced Pirani gauge is more accurate than a thermocouple gauge, especially at lower pressures. And depending on your gauge/readout configuration, the cost of a Stinger is about the same cost of a TC gauge system. Also a direct drop-in replacement for Mini-Convectron® The CVM211 Stinger can also directly replace the most basic Granville-Phillips® Mini-Convectron® modules, at significantly lower cost. The InstruTech Stinger provides equivalent or better performance throughout the range of 10-4 to 1000 Torr. The 9-pin D-sub connector has the same pinouts and signals as the corresponding Mini-Convectrons®. The non-linear analog signal and setpoint relay are identical to their corresponding Mini-Convectron® functions. With Stinger's performance, more robust design, longevity, smaller size, and lower cost, your process will only improve. CVM211 Built-in Controller & Display InstruTech's CVM211 Stinger module provides the necessary signal conditioning to turn the convection gauge into a complete vacuum measuring instrument. The CVM211 Stinger module provides one log-linear or non-linear analog output and one setpoint relay. In addition, a built-in display provides the measured pressure values and provides a convenient user interface for setup and operation of the vacuum gauge. 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 CVM211 Stinger offers a cost-effective solution for your vacuum gauging needs.
