Energy in our modern industrial society is basically required in two forms: as heat and as motion energy. The utilization of energy optimized for maximum efficiency extends from its generation over its transmission to the end user. Sensors and measuring systems provide important data on the energy conversion and transport processes along the way. In power plants, for instance, this data comprises temperature, pressure, and flow from ever more process areas or the exact composition of combustion gases. In turbines, generators, or wind power stations, measuring systems monitor status and attrition to enable efficient operation. During transmission and distribution of electric energy, power analyzers and network quality measuring equipment are applied.

  

Sensor and measuring technology are used also on the consumer side, to guarantee maximum energy efficiency. Thus sensors enable demand-oriented regulation of air-conditioning and ventilation systems in dependence on the carbon-dioxide concentration for an energy saving of 20% to 70% compared to non-regulated systems. Another interesting application that contributes to an efficient utilization of energy is leakage monitoring of compressed-air systems. Pressurized air is an expensive form of energy and even the smallest amount of leakage leads to high costs. Monitoring equipment for such systems are a good example of how innovative sensor and measuring technology pays off in a very short period of time.

 

Another area that has a great portion of the overall energy consumption is building HVAC (heating, ventilation, and air conditioning). Enormous energy savings can be achieved here by optimized construction measures as well as by changing usage patterns. State-of-the-art thermography devices indentify energy vulnerabilities in buildings at increasingly low cost and newly developed gas sensors provide the decisive impulse for accurate, demand-oriented HVAC systems.

 

These novelties and other interesting applications can be seen from 18 to 20 May at the SENSOR+TEST. An Efficiency Forum with table-top exhibits and poster sessions is dedicated to this focal topic. On the first day of the fair, lectures and podium discussion are to be held in Hall 12 on the subject of energy efficiency. The visitor will thus be provided with a good overview of the relevant applications.
