5600-3071 GDX-350 Gas Sensor Transmitter/Monitor, [PH3] 0-10 ppm, 3-wire by Bacharach

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.

Features & Benefits:

  • Pre-calibrated Smart Sensor capability with 'plug-n-play' convenience minimizes maintenance and downtime
  • Non-Dispersive Infrared (NDIR), Catalytic Bead and Electrochemical sensor options available
  • Can be placed directly in hazardous environments where leaks occur for quick detection and rapid response
  • Graphic LCD for real-time monitoring of concentrations
  • 4-20 mA, optional Modbus RTUŽ and wireless interface
  • Easily update alarm set points, configurations or maintenance modes using the LCD display
  • 30-minute onboard data trend
