Description
The InstruTech series 3000 B-RAX is a highly versatile vacuum gauge controller capable of operating one ionization gauge (IG) and up to two
CVG101 convection vacuum gauge sensors (CG), or one IG, one CG and one alternate gauge such as a capacitance diaphragm gauge (CDG).
The ionization gauge on/off, degas functions and emission current selection can be controlled via front panel soft-keys, remote input signals
(Digital I/O), or serial communications. IG sensor can also be automatically turned on/off using the measurements from one of the user
selectable convection or alternate gauges. When using hot cathode IGs, the B-RAX can be set to automatically switch (auto-ranging) between
various emission currents. This results in optimal and stabile pressure readings over the entire measurement range from low to high vacuum.
High efficiency power supply design and effective thermal management techniques are used to enable operation of the B-RAX without the
need for air movement devices such as troublesome fans. The state of all setpoint relays, emission current, filament in use and error
messages for all fault conditions are displayed on the easy to read OLED set-up screen. Filament operation including filament current,
emission current and ion current can be monitored in real time in the research screen mode.
