The InstruTech CVM201 Super Bee vacuum gauge module has a wide measurement range from 1.0 x 10-4 to 1000 Torr and includes a digital display, analog outputs, and communications. It offers significant cost savings over other gauges as it incorporates design improvements that increase reliability while reducing parts and complexity. The CVM201 can also directly replace most Granville-Phillips Mini-Convectron modules using the same connections and software commands. It provides equivalent or better performance at a lower cost.

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 convection enhanced Pirani vacuum gauge with significant cost savings that are passed on to the user. The InstruTech CVM201 Super Bee provides the basic signal conditioning required to turn the gauge into a complete measuring instrument. Similar feature filled design philosophy is incorporated into the module electronics. The CVM201 Super Bee provides non-linear or log-linear and linear analog outputs, two setpoint relays and RS232/485 serial communications. A built-in OLED digital display provides the measured pressure values and provides for a convenient user interface for setup and operation of the vacuum gauge. The biggest cost savings is from manufacturing a single model, with all possible options, instead of making dozens of different pc boards and models. And you don't have to give up one feature to get another you want. 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 CVM201 Super Bee offers a cost-effective solution for your vacuum gauging needs. Also a direct drop-in plug-compatible replacement for the Mini-Convectron® The InstruTech CVM201 Super Bee module will also directly replace most Granville-Phillips® Mini-Convectron® modules. The InstruTech Super Bee provides equivalent or better performance throughout the range of 10-4 to 1000 Torr. Linear and non-linear analog signals, digital interfaces, and setpoint relays are all included in the standard InstruTech module. All are identical to their corresponding Mini- Convectron® functions. Software commands are the same. One InstruTech CVM201 Super Bee can directly replace dozens of different Mini-Convectron® configurations, reducing the number of spares you need to keep on hand. The 9-pin D-sub and 15 pin D-sub connectors have the same pinouts and signals as the corresponding Mini-Convectrons®. With Super Bee’s performance, more robust design, longevity, and lower cost, your process will only improve.
