Standalone Operation in Harsh Environments
Bacharach's new state-of-the-art GDX-350 transmitters, with Smart Sensor technology, provide accurate and
continuous detection of toxic, combustible and asphyxiate gases. The full-featured design of the GDX-350
includes a large LCD display, a 4-20 mA interface, programmable alarms, optional relays and a Modbus interface.
Exclusive pre-calibrated replacement sensor technology makes occasional maintenance practically effortless.
Rugged construction, intrinsic safety capability (in two-wire mode with barrier) and an explosion-proof housing
allow the GDX-350 to operate directly in hazardous-rated areas of many industrial environments, delivering
reliable, superior-sensing performance to protect human life, equipment and property.
With its large LCD display, the GDX-350 shows gas concentrations, engineering units and bar graphs along with
the most recent 30 minutes of trend data. Utilizing the on-board magnetic keypad, users can also navigate
through the display to change alarm set points, instrument configurations, or enter into maintenance mode for
non-intrusive sensor calibration. For security, menu options also enable the selection of an authorization code to
lock critical parameters. Accompanying the LCD display are standard LED alarm indicators that show when low
and high alarm conditions are met. An optional relay board is available to provide three 5-amp relays that can be
used to drive audible/visual alarms, or activate exhaust fans.
