Features
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.
- Wide Measurement Range: Vacuum system pressure can be monitored continuously from 1x10-4 Torr (1x10-4 mbar, 1x10-2 Pa) to atmosphere.
- High Measurement Resolution: Designed to take full advantage of Convectron Gauge technology with 1 Torr (1 mbar, 0.1 Pa) resolution at atmosphere and 0.1 mTorr (1x10-4 mbar, 1x10-2 Pa) resolution at low pressure.
- Vacuum Fluorescent Display: The VFD is easier to read from greater distances than other types of displays. The display is configurable to use scientific notation or two ranges (Torr and mTorr, mbar and 10-3 mbar, or kPa and Pa) to provide a continuous measurement readout from atmosphere to low pressure.
- Process Set Point Option: Relay contacts allow control of other vacuum equipment, such as valves, pumps, heaters, alarms, and safety interlocking.
- Multiple Gas Curves: Selectable N2 , Ar, He, CO2 and O2 gas curves are pre-programmed, eliminating the need for individual calibration when changing the process gas.
- Push-Button Controls: Calibration and set point settings are easy to adjust using intuitive front panel controls. No special tools are required.
- Easy-to-use Analog Signals: Provides a one volt per decade logarithmic signal (0-7V or 1-8V) or a selectable non-linear signal (0-9V) that is backwards compatible with older Convectron gauge controllers.
- Serial Communication Interface Option: RS-232 interface allows easy integration with computer controlled systems.
- Built-in Convectron Gauge Simulator: Simulates a Convectron gauge, which allows system diagnostics without the need of a vacuum system.
- Self Diagnostics: The A/D (Convectron gauge bridge voltage) and analog outputs are continuously monitored for erroneous readings.
- Compact 1/8 DIN Controller: Easy to install in space restricted locations.
- Rugged All-Metal Package: Provides a high level of immunity to RF noise
Controls 275 Convectron® Pirani Vacuum Gauges
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.
