WWW.MKSINST.COM Series 475 ConveCtron® vaC uu M Gau G e Controller The Series 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 that features individually calibrated gauges, temperature compensation and convection technology for increased accuracy and repeatable vacuum measurements over seven decades from 1x10 -4 Torr (1x10-4 mbar; 1 x10-2 Pa) 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. The Series 475 Convectron Controller can be used as a simple readout device for basic vacuum system control or integrated into a more sophisticated control system. The Series 475 Controller 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 Series 475 Convectron Controller and Convectron technology the ideal solution for today’s vacuum measurement systems. Features & Benefits

Description

  • Wide Measurement r ange: Vacuum system pressure can be monitored contin uously from 1x10-4 Torr (1x10-4 mbar, 1x10-2 Pa) to atmosphere. High Measurement r esolution: Designed to take full adv antage 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 Displa y: The VFD is easier to read from g reater distances than other types of displays. The displa y is configurable to use scientific notation or tw o ranges (Torr and mTorr, mbar and 10-3 mbar, or kPa and P a) to provide a continuous measurement readout from atmosphere to lo w pressure. Pr ocess Set Point o ption: Relay contacts allow control of other v acuum equipment, such as valves, pumps, heaters , alarms, and safety interlocking. Multiple Gas Cur ves: Selectable N2, Ar, He, CO2 and O2 gas curves are pre-programmed, eliminating the need f or individual calibration when changing the process gas Push-Button Contr ols: Calibration and set point settings are easy to adjust using intuitiv e front panel controls . No special tools are required. e asy-to-use a nalog Signals: Provides a one volt per decade logar ithmic signal (0-7V or 1-8V) or a selectable non-linear signal (0-9V) that is bac kwards compatible with older Con vectron gauge controllers. Serial Comm unication Interface o ption: RS-232 interf ace allows easy integration with computer controlled systems Built-in Con vectron Gauge Simulator: Simulates a Con vectron gauge, which allows system diagnostics without the need of a v acuum system. Self Dia gnostics: The A/D (Convectron gauge bridge v oltage) and analog outputs are continuously monitored f or erroneous readings. Compact 1/8 DI n Controller: Easy to install in space restr icted locations. r ugged a ll-Metal Package: Provides a high level of imm unity to RF noise

Correction parameters for common gases are provided in the instruction manual. 2 Con vectron Gauges are not intended for use with flammable or explosive gases. Analog Output Signals — Standard analog output is 0 to 7 Volts that is linear in voltage with the log of pressure. Two alternate analog outputs can be selected using the front panel b uttons: either 1 to 8 Volts that is linear in voltage with the log of pressure or 0 to 9 Volts that is non-linear with the log of pressure and mimics the output of older v acuum gauge controllers.
