GTD-2000ExW flammable gas detector has been developed to detect gas leaked from industrial sites and various
flammable gases generated from factories, gas storages, and manufacturing processes that produce or use toxic gases
and to prevent accidents in advance.
GTD-2000ExW flammable gas detector is installed in areas with gas leak hazards and continuously monitors gas leak. It
displays measurements on LCD of the detector, converts and transmits data in DC 4~20 mA standard output signal. Also,
for DC 4~20 mA standard output, output signal transmission length between detector and receiver can be connected up
to 2,500 m. (When Cable CVVS or CVVSB 1.5sq and higher is used.) GTD-2000Ex flammable gas detector must be used
at a height below 1,000 m above sea level.

Instruction Manual
Body of GTD-2000Ex 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 areas with combustible gas leak and
explosion hazards. It has built-in display (LCD or OLED) on the detector to display gas leak status at installed site. Internal
configuration consists of display part that indicates measurements, terminal part that output measurements (DC 4~20
mA) externally, and a PCB board. External configuration consists of sensor that detects gas leak, cable inlet, and high-
pressure explosion proof small warning light made of SUS materials. It uses magnet-bar outside the main body of
detector enabling calibration from the outside of the detector, thus, maintenance is convenient.
