3. Specification
GTD-1000Tx(M) toxic gas detector has been developed to detect gas leaked from industrial sites and various toxic gases
generated from factories, gas storages, and manufacturing processes that produce or use toxic gases and to prevent
accidents in advance.
GTD-1000Tx(M) toxic gas detector is installed in areas with gas leak hazards and continuously monitors gas leak. It
provides DC 4-20 mA standard output signal and RS-485 network signal. Also, DC 4~20 mA standard output enables
transmission distance of the output signal between detector and receiver at maximum 2,500 m (when using cables with
CVVS or CVVSB 1.5 sq or higher). RS-485 network signal can be transmitted up to 1,000 m (when using a designated
cable for RS-485). GTD-1000Tx(M) toxic gas detect must be used at a height below 1,000 m above sea level.
Body of GTD-1000Tx(M) is made of Aluminum alloy and the gas sensor module is made of stainless steel. It consists of
a complete explosion-proof enclosure (Ex d IIC T6). This product can be installed in all areas prone to toxic gas leak and
explosion hazards.
Internal configuration consists of 1 terminal PCB board that outputs measurements externally (DC 4-20 mA, RS-485).
External configuration consists of detector part that monitors gas leak and cable inlets.
It can perform calibration using detachable display (LCD or OLED), therefore maintenance is convenient.
