OVERVIEW
Operating at 24 VDC and gives a 4-20 mA o/p over the range of the oxygen or toxic sensor to which it is calibrated. The gas detector/gas sensor 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. This allows calibration without a hot work permit.
Key Features
- Continuous detection of toxic gases & oxygen in ZONE 1 areas.
- Flame proof structure Self diagnosis function with built-in Microprocessor
- Excellent selectivity for toxic gases & oxygen
- Superior performance for detecting gases below TLV
- Multi functions with low cost of ownership
- Built-in back light LCD display
- Auto calibration and program setting with a magnet bar ( no hot work permit required )
- 4-20 mA DC output signal
- Calibration and maintenance by one-man
APPLICATIONS
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
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.
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
Designed, Manufactured and Supported in Australia.
