Vacuum Gauge Controller VGC103
Vacuum Gauge Controller VGC103
By combining up to three principles of measurement Ð from hot
cathode, cold cathode, Pirani or capacitance diaphragm gauges Ð
the Vacuum Gauge Controller VGC103 covers the entire pressure
range from 10 -10 to 2000 mbar (Torr). Switching over of the display
to the right pressure range is automatic for the most common sensor
combinations. The display of the VGC103 combines the advantages
of analog and digital readouts.
Advantages
♦ Can be combined with up to three sensor types for an extremely wide
measurement range
♦ Full remote control via RS 232 C interface
♦ User selectable measurement unit (millibar, Torr, Pascal or micron)
♦ Analog bar graph display compliments digital readout
♦ Three adjustable setpoints with adjustable hysteresis, may be assigned
to any channel
♦ Programmable 0 É 10 V chart recorder output with logarithmic / linear
characteristics for each gauge or combination of PSG and BAG
♦ Compact bench-top unit which can be installed in panel cut-outs or a
19Ó racks (1/4 19Ó, 3U height)
The VGC103 easily fits your application specifications thanks to the
possibility of combining various sensors with different methods of
measurement and different measurement ranges.
Multiple Recorder Outputs and Control
Signals For Simplified Process Integration
The VGC103 offers standard features that other controllers only offer as
add-on options:
♦ Three adjustable setpoints with adjustable hysteresis and arbitrary
allocation to the three measuring channels
♦ Automatic control of the emission (Bayard-Alpert Gauge BAG) or of high
voltage (Penning Gauge PEG) with Pirani Gauge PSG on channel 2
Easy To Read – Easy To Use
The large digital display allows for easy and quick reading of the
measurement value, while the analog bar graph display allows for at a
glance verification. During pressure measurement the display changes
automatically over to the input channel of the correct sensor for the sensor
combination: Ch 2 = PSG, Ch 3 = BAG. The values can be displayed in
millibar, Torr, Pascal or micron.
With its compact dimensions the VGC (1/4 19Ó, 3U height) easily fits
into panel cutouts or 19Ó racks and can be used just as easily as a
bench top unit.
