Series 301 Convection Vacuum Gauge Controller
Wide measuring range lets you monitor your vacuum system
-4
from 1 x 10 to 1,000 Torr with a single gauge
Includes two setpoint relays, user-selectable analog output,
and RS232 / RS485 serial communications
Analog output is configurable as a non-linear S-curve,
log-linear, or user-scalable linear voltage signal
Space-saving 1/8-DIN panel mount housing easily adapts to
instrument or rack-mount panel installations
Description
The VGC301 vacuum gauge controller is a convenient and
inexpensive power supply and readout instrument for a
CVG101 Worker Bee™ convection vacuum gauge sensor.
The 1/8-DIN housing can be used as a bench top or a
panel mount instrument. The VGC301 is powered by
user supplied 12 to 28 Vdc, 2 W, or by InstruTech series
PS301 optional power supplies.
Compatibility: Signals and relay functions are the same as
found on similar convection gauge controllers from other
manufacturers. The VGC301 controller, CVG101 vacuum gauge
sensor and cable can be directly interchanged with GranvillePhillips® 375 and 475 controllers, 275 Convectron® gauge and
gauge cable (Remote interface, relay, and power connectors are
different).
