(operating system updates is not required)

Description
The FlexRax® is a 19-inch wide, 2U, full-rack vacuum gauge controller capable of operating
multiple vacuum gauges simultaneously. The type and number of gauges operated will
depend on user specified option cards installed at the factory. This results in significant
cost savings since the user can specify a FlexRax configuration to operate only the gauges
required for the application. Furthermore, the user can easily install additional option
cards in the field for future expansion of gauges to operate.

Compatible Vacuum Gauges

BA601

BA602

BA603

FlexRax can operate up to 10 vacuum gauges simultaneously as listed below:
● Up to a total of four ionization gauges (IG) configurable for:
A) Up to two classic size BA600 series Bayard-Alpert (B-A) glass or nude ionization
gauges or other equivalent brands of glass/nude B-A IG
B) Up to two InstruTech® IGM400 Hot Cathode or two CCM500 cold cathode IG modules
● Up to four CVG101 convection gauges (CG)

IGM400
CCM500
CVG101
Hot Cathode Cold Cathode Convection

● Up to two analog input signals from other devices such as capacitance diaphragm
gauges (CDG) or InstruTech CVM201, CVM211, IGM401 and CCM501 gauge modules

Features
Easy to read LCD with backlighting provides sharp contrast with wide viewing angle. The instrument can be configured to display up to
6 gauges in a single screen or assign any number of gauges to various screens for auto-scrolling of display. The state of all setpoint
relays and engineering units of measure will be displayed on the main screen. Filament operation including filament current, emission
current and ion current can be monitored in real time on research screens. The system can be personalized by assigning specific
names to individual gauges or use the factory default gauge symbols. Error messages will be displayed for all fault conditions.
High efficiency power supply design and effective thermal management techniques are used to enable operation of the FlexRax
without the need for air movement devices such as troublesome fans often required in even single ionization gauge power supplies.
Filament switching control from the FlexRax combined with capability to operate two conventional B-A ionization gauges
simultaneously, offers the user low cost of ownership and unparalleled ease of use.
