Expansion of Fixed Gas Detection Transmitters

Bacharach (USA) is pleased to announce the expansion of their GDX-350 Series of fixed gas detection transmitters. Designed to withstand the harsh environments common in industrial applications, the GDX-350 Industrial Transmitters offer an expanded range of sensors for the detection of toxic, combustible and asphyxiate gases in an intrinsically-safe or explosion-proof housing. The GDX-350 transmitters are full featured transmitters designed for integration into any existing system or as a complete solution for new installations. Placing the transmitters in locations where leaks can occur allows for quick detection and response to the smallest breach, protecting human life as well as equipment and property. The GDX-350 can be used with the GDA-400 or GDA-1600 Controllers to provide simultaneous display and alarm functions for up to 16 monitors.

The GDX-350 series features a large LCD graphic display that shows gas concentrations and engineering units, along with the flexibility to show the last 30 minutes worth of historical data. Utilising the display panel, users can also navigate through the menu to change alarm set points, instrument configurations, or enter into maintenance mode for sensor calibration. Standard LED alarm indicators accompany the display, indicating 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.

Pre-calibrated, user-replaceable “smart-sensors” are available for the GDX-350 transmitters which minimise downtime, reduce costs and simplify basic instrument maintenance by eliminating the need for technicians to perform gas calibrations in the field.

Product feature include: NDIR, Catalytic and Electrochemical sensors available; Electrochemical sensors for detecting CO, O2, H2S, SO2, NO2, H2, PH3 & NH3; Infrared (IR) sensor for detecting CO2; Combustible gas detection with catalytic bead or IR sensor technology; 2 or 3-wire 4-20 mA interface; Graphic LCD for real time monitoring of concentrations; Relay outputs (optional); Optional Modbus RTU interface; Optional wireless data interface; 30 minute onboard data logger; Easy maintenance w/pre-calibrated replacement sensors; Intrinsically safe 2-wire versions; Explosion-proof rated 3-wire versions.
