Bacharach GDX-350 Series fixed gas-detection transmitters

Bacharach has expanded its GDX-350 Series of fixed gas-detection transmitters. Designed to withstand the harsh environments common in industrial applications, the 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.

Full-featured transmitters, they are designed for integration into any existing system or as a complete solution for new installations. 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 series features a large, graphic LCD that shows gas concentrations and engineering units, along with the flexibility to show the last 30 minutes’ worth of historical data. Using 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 A 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.
