Centrally located, practice-oriented and innovative. The University of Technology Sydney is a public research university for engineering and natural science subjects as well as for the Business School sector. There are now over 40,000 students studying at UTS. The university is considered one of the world’s leading young universities and is ranked 1st in Australia and 11th in the world in the QS World University Ranking 2021.

For the protection of people working and learning for example in the areas of natural science, such as biomedicine, chemistry, forensics, marine, physics or even biotechnology, CO2 and CH4 gas warning systems from MSR-Electronic were installed to ensure the monitoring of combustible and toxic gases as well as of oxygen deficiency.





MSR-Electronic solution: gas warning systems


Analog gas sensors (type MC2) are used for the laboratory environment, and PolyXeta®2 sensors, which are specially certified for the ATEX area, are used for the hazardous, explosive area in the gas cylinder warehouse.

Each level has its own controller and the corresponding sensors. An RS-485 Modbus interface is integrated in the controller (type DGC-06). The high-level interface with Modbus protocol transmits all sensor values, the relay status (ON or OFF) and also any system malfunction to the BMS on site in real time.


Analog gas sensor MC2


The sensor is used for the detection of toxic gases or for oxygen monitoring when a classic 4-20 mA signal (or 2-10 V) is required.

The sensor includes:

  • digitalised measured value processing
  • temperature compensation
  • self-monitoring

The sensor head contains:

  • electrochemical sensor element with measuring amplifier
  • module with μController
  • analog output
  • power supply

PolyXeta®2 gas sensor for ATEX area


The sensor is used in industrial areas like:

The PolyXeta®2 sensor is also suitable for commercial areas like gas transfer stations etc. With the 4–20 mA / RS-485-Modbus output signal the sensor is suitable for connection to the PolyGard®2 gas controller series by MSR-Electronic, as well as to any other controllers or automation devices. Optionally, the PolyXeta®2 sensor is also available with LCD display and relay output.

Gas-Controller-System DGC-06


The Controller is used for the monitoring and warning of toxic and combustible gases and vapours as well as of Freon refrigerants within a wide range of the gas measurement technique. Numerous adjustable parameters and set-points permit individual adaptation to many applications.

The DGC-06 Gas-Controller fulfils in addition the functions of monitoring carbon monoxide (CO) in garages, tunnels and cart tracks etc. and is compliant to the current EN 50545-1.




The entire support and installation of the CO2 and CH4 gas warning systems of MSR-Electronic in the University of Technology Sydney was carried out by the MSR partner ALVI Technologies Pty Ltd..

ALVI distributes gas warning devices from MSR-Electronic in Australia, New Zealand and Southeast Asia.
