Biogas plants produce biogas as the result of the fermentation of biomass, and this energy source is in great demand. Increasing numbers of agricultural concerns rely on biogas to produce electricity and heat. But commercial plants which produce biogas from municipal, commercial and industrial waste are also becoming more important.
To guarantee the efficiency of this type of plant, it is necessary to control and monitor the fermentation and gas production processes. Angst+Pfister Sensors and Power offers gas and oxygen sensors to monitor the quality of the gas. When carrying out this type of measurement, it is important to use sensors which are selective, robust, low-maintenance, and non-hazardous. The paramagnetic measurement principle has become the established means of measuring oxygen. However, the NDIR measurement principle is still standard for measuring CH4. Sensors using both measurement principles are available in various measurement ranges and with analogue and digital output signals.
Gas storage levels in biogas plants can be recorded by means of cable-actuated position sensors. Angst+Pfister Sensors and Power offers a wide range of cable-actuated position sensors which measure storage levels reliably. Interfaces of various descriptions ranging from analogue to bus systems (CANopen, PROFIBUS, DeviceNet, etc.) are available for connecting to the control unit.
We can also develop tailor-made solutions in conjunction with customers and provide professional support during their development projects.
