Instruction Manual
GTD-2000TxW 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-2000TxW toxic gas detector is installed in areas with toxic gas leak hazards and continuously monitors gas
leak. It displays measurements on built-in displays (LCD or OLED) of the detector, delivers alarm status with visible
and audible signals using a warning light, and provides 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-2000TxW flammable gas detector must be used at
height below 1,000 m above sea level.
Body of GTD-2000TxW 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 flammable gas leak
and explosion hazards. It has built-in LCD on the detector to display gas leak status at installed site. It consists of
display part that indicates measurements, terminal part that output measurements (DC 4~-20mA) 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.
