Hargassner relies on gas sensors from MSR-Electronic

Hargassner relies on gas sensors from MSR-Electronic

15 September 2023

MSR-Electronic GmbH in Pocking installs innovative gas sensors for detecting gas in the boiler room at Hargassner.

Hargassner stands for eco-friendly heating with renewable energies such as biomass, pellets, wood chip boilers and wood logs. Especially in closed boiler rooms with infrequent traffic, the multitude of toxic gases and explosive areas creates a high risk of explosions and dangerous gas leakage.

Hargassner’s CHP (combined heat and power) wood gasification system is used to produce heat and power from biomass. Any leaks in the system process are hard to detect due to the conditions in place. MSR-Electronic gas sensors detect even the smallest gas leaks in the process, ensuring the utmost safety for the operator at all times.

Up to 50 MSR-Electronic gas detectors are used to continuously detect gas so that people and plants in the company’s boiler room have maximum protection.

How does gas detection work in boiler rooms?

The gas sensors continuously monitor the ambient air and the CO concentration in the boiler room and are built into a switch cabinet. For maximum safety for people and plants, gas sensors are installed near the floor and ceiling.

MSR-Electronic solutions

Gas sensors (type MC2) are used in the Hargassner boiler room to measure toxic gases in the ambient air and to monitor the oxygen concentration.

A module with μC, analogue output and power supply is integrated into the interchangeable sensor unit with digital measurement value processing, temperature compensation and self-monitoring in addition to the electrochemical sensor element with amplifier.

The µCcontroller uses the sensor's measurement signal to calculate a linear 4-20 mA signal (or 2-10 V); the relevant measuring values and sensor element data are also stored. The sensor unit can be calibrated by simply switching it out or by going through the integrated, convenient calibration routine on the plant itself


  • Digital measurement value processing incl. temperature compensation 
  • Internal function monitoring with integrated Watchdog
  • High accuracy, selectivity and reliability
  • Low zero drift
  • Sensor with long lifetime 
  • Hardware and software according to SIL-compliant development process 
  • Reverse polarity protected, overload-proof and short-circuit proof 
  • Housing for holding the sensor unit 
  • Display
  • Display with 2 open-collector outputs for horn and warning light
  • Duct mounting set

The controller for GC-06 is built into the switch cabinet at Hargassner to monitor and evaluate the gas sensors. The gas controller is designed in accordance with EN 50545-1 and other standards, and can monitor and evaluate up to 100 gas sensors.

The freely adjustable parameters and set points allow it to be used flexibly in many gas measuring technology applications. An easy to use system menu with a logical structure, right on the controller and requiring no special programming skills, is used to configure, operate and set the parameters. Alternatively, the PCE06 Software allows users to load, modify and save application parameters via a serial interface.

The GC-06 has been configured and set according to customer specifications. The plants were thus able to be installed by Hargassner using Plug&Play.
