GDA 7228 : Flush Mount Oxygen Gas Sensor
The 7228 Flush Mount Oxygen gas sensor is a 2 wire 4-20 mA Loop Powered device with a range of 0-25% vol Oxygen.
DESIGNED, MANUFACTURED and SUPPORTED by GAS DETECTION AUSTRALIA.
The 7228 has an electrochemical gas sensing unit which is temperature compensated. The gas sensor element is on a pluggable lead allow ease of replacement. It is designed to fit into a Clipsal double gang GPO wall mount. The total protrusion from the wall is 13 mm; the sensor head and its electronics are housed in a metal enclosure giving it excellent RFI and EMC compatibility.
- Single man calibration at the gas sensor
- 4-20 mA o/p
- Low cost replaceable sensor element
- 24 VDC operation
- Flush wall mounted housing. To fit in with office environment
- Easy to install

| Cryogenic Rooms | Cryogenic freezing using liquid Nitrogen poses a problem of oxygen depletion. The GDA 2528 oxygen gas detector / gas sensor offers a cost effective method of detection and low cost of maintenance. For standalone cyro-storage chambers housed in laboratories , the storage area can be monitored for oxygen depletion by the standalone GD40125 system. DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA. |
| Cellar Gas Detection | The ACGS-01 uses the latest patented laser source technology to provide reliable accurate and cost effective solutions for Carbon Dioxide gas detection in cellar gas detection applications. The Carbon dioxide cellar gas detection system ACGS-01 comprises of a remote carbon dioxide gas detector / gas sensor, an external control unit + power supply (to view the gas levels and alarms before entry ) and a audio visual sounder/ flasher that will activate on alarm. Gas Detection Australia offer a range of solutions to meet individual site requirements for carbon dioxide cellar gas detection systems and oxygen cellar gas detection when using nitrogen for pre-mix drinks MEETS THE REQUIREMENTS OF AS5034-2005. DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA. |
| Ambient Air Monitoring | A reliable low cost sensor to monitor the CO2 levels allowing an interface to a BMS system. The GDA 4350 series of flush wall mounted CO2 sensorsare designed fro internal use fitting into a Clipsal double gang switch box aperture |
| Refrigerant Gas: Plant Rooms & Offices | Gas Detection Australia has a range of ultra-low level refrigerant gas leak detection systems specifically developed to prevent the expensive results of refrigerant gas leaks.. R22; R123; R134, R407; R410; Ammonia, Carbon Dioxide; Propane MEETS THE REQUIREMENTS OF AS 1677.1 & 2 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. |
| Food Processing | Purgative gases such as Chlorine and Sulphur Dioxide present OHS requirements for workspace monitoring. Ammonia is often used as a refrigerant gas and can present OHS requirements for monitoring. Carbon Dioxide used in food packaging and stored on site needs to be monitored. |
| Flush Mount Gas Sensors | Mounted in wall hole, Non obtrusive, recommended for office rooms, class rooms, laboratories etc. Are designed to fit into a Clipsal double gang GPO wall mount. DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA. |
| Air Conditioning Monitoring | Air conditioning gas detection systems are used in a number of ways. In air conditioning plant rooms Gas Detection Australia has gas sensors and gas detectors for Ammonia , Propane, CO2 and R134a, R123, R125, R404, R407c R410a etc. In enclosed laboratories classrooms and workspaces. The Gas Detection Australia range of flush mounted Air Conditioning gas sensors for Carbon Dioxide GDA 4360 are used by the HVAC industry to control fresh air input into rooms and modulate supply. In the case of VRF systems needing room air conditioning gas detection HVAC industry uses the flush mounted GDA 3160 which are unobtrusive and used to detect low levels of R134a, R123, R404, R407c, R410 etc. DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA. |
