The GDA 2000Ex Flammable Gas Detector is certified for use in Zone 1 Hazardous areas within Australia.

Locally Technically Supported by Gas Detection Australia

IECEx Approved

Operating at 24 VDC and gives a 4-20 mA output over the range of the flammable gas to which it is calibrated. The gas detector can be programmed and calibrated without opening. The display indicates the gas level reading. It is fitted with a sensor splash cover giving a head IP rating of IP66. The sensor does not have to be opened to carry out a calibration as all programming can be carried out via an external magnetic switch, allowing calibration without a hot work permit.

  • Continuous detection of flammable gases in Zone 1 areas
  • IEC Ex approved
  • 4-20 mA output
  • 0-100% LEL
  • 24 VDC operation
  • Single man calibration
  • No hot work permit required
  • Available for many hydrocarbon gases.

Hazardous Areas (IEC Ex Certified)

IEC Ex approved gas detectors and sensors for use in Zone 1 and Zone 2 areas within Australia for both Toxic and Flammable gases.

Hazardous Areas are areas in which an explosive gas atmosphere is or may be expected to be present, in quantities such as to require special precautions for the construction installation and use of equipment construction, installation and use of equipment. Hazardous areas are classified into 3 zones based upon the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:

  • Zone 0 - Area in which an explosive gas atmosphere is present continuously or for long periods or frequently.
  • Zone 1 - Area in which an explosive gas atmosphere is in which an explosive gas atmosphere is likely to occur in normal likely to occur in normal operation occasionally.
  • Zone 2 - Area in which an explosive gas atmosphere is not likely to occur in normal operation but, if it does occur, will persist will persist for a short period for a short period only.
  • Non hazardous area (safe area) - A non hazardous area is an area in which an explosive atmosphere is not expected to be present.

As per IEC60079-10-1 and AS/NZS 60079.29.2:2016

Generator Rooms

A range of devices from single point go / no go detectors such as the DA-2010 through to sophisticated IEC Ex type gas detectors / gas sensors can be used for detection of Natural gas, Propane, Butane and various other mixtures.

Designed, Manufactured and Supported in Australia.

Sewage Treatment Plant Monitoring

The presence of Hydrogen Sulphide  can be detected by using the Gas Detection Australia GDA 2529 gas sensor to detect leaks of Hydrogen Sulphide  and evoke deodorisation plant. The SI-100C gas sensor can be used to monitor for leaks of LEL levels of methane gas. In digester applications Carbon dioxide can be detected using the GDA 4350  

Designed, Manufactured and Supported in Australia.

Battery Room Monitoring

The SI-100C and a range of associated Gas Detection Australia controllers can be used in battery room gas detection  to detect hydrogen in battery rooms and sound alarms. The battery room gas detection systems comprise of a hydrogen gas sensor SI-100C and a gas sensor control unit. The Gas Detection Australia control unit  GDA 4020 or GDA 4011 is situated external to the battery room to display the gas concentrations and the alarm status. The battery room gas detection system can then be interfaced to extraction fans, sounders or other apparatus. For smaller battery charging rooms the standalone GDA 40126 can provide an integrated sensor and controller with outputs to drive extraction fans and sounders.

Designed, Manufactured and Supported in Australia.

Laboratory and Classroom Monitoring

When gas is piped into rooms for experimental purposes such as CO2, CO, or Natural Gas .The Gas Detection Australia range of sensors can be used to detect any leaks that may present a danger to health or explosion.

Designed, Manufactured and Supported in Australia.
