The Granville-Phillips® 475 Convectron® Vacuum Gauge Controller combines with the industry-standard Series 275 Convectron® gauge to provide high performance vacuum pressure measurement using a unique variation of thermal conductivity. The Convectron® gauge is a convection-enhanced Pirani design vacuum gauge that features individually calibrated gauges, temperature compensation and convection technology for increased accuracy and repeatable vacuum measurements over seven decades from 1x10-4 Torr to Atmosphere.
The Series 475 Convectron Controller is a third-generation RoHS compliant Convectron gauge controller that combines rugged reliability with key features for ease of use and system integration. It includes several features such as self-diagnostics, integrated Convectron gauge simulation, and built-in gas curves to adjust for various vacuum environments. The Series 475 is easy to use with a highly visible Vacuum Florescent Display (VFD) and intuitive front panel controls that allow gauge calibration and adjustment of vacuum measurement parameters without the need for special tools. It can be used as a simple readout device for basic vacuum system control or integrated into a more sophisticated control system. The 475 provides a range of control I/O options including an analog output, set point relays and a serial communication interface. The compact packaging and innovative electronics make the 475 Convectron Controller and Convectron technology the ideal solution for today’s vacuum measurement systems.
These controllers are designed to work with 275 Convectron® Pirani Vacuum Gauges. Granville-Phillips® Convectron® Gauges have been the world-standard convection-enhanced Pirani gauge for over 35 years and are used in thousands of vacuum processes to accurately measure pressure from atmosphere to 10-4 Torr.
