| Hazardous Areas (IEC Ex Certified) | IEC Ex approved gas detectors and sensors for use in Zone 1 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:
As per IEC60079-10-1 |
| 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. |

SENKO SI-100 : Explosion Proof Gas Detector
SI-100 is a IEC Ex fixed gas detector installed in a place where potential gas hazard occurs to measure oxygen, toxic gas and combustible gas. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LCD display and can be connected to the controller with a standard 4-20mA analog output communication or RS-485 digital communication.
GDA 4020 : Two Channel Gas Detection Controller
The GDA 4020 control unit has 2 x 4-20 mA i/p with 3 associated programmable relay alarm levels per sensor. There is an independent fault relay. There are 3 x analog o/p’s which can be configured for either channel as 4-20 mA, 0-20 mA, 0-5 V or 0-10 V. The controller has an isolated RS485 o/p which can be configured to drive modbus or an interface to the M2001 mimic panel. All configurations are carried out via the front panel push buttons. The unit requires 24 VDC.
