eng: Nowadays, climate protection plays a key role for the European Union and is declared as a mandatory goal by increasing the amount of renewable energy to 20% by 2020. Using the giant mass of waste ecologically to process electrical energy via a biomass plant is an important way to reach this goal. One big problem of biomass plants is the cost efficiency caused by high maintenance costs which can be reduced by using a corrosion sensor additional to other sensor-principles. This sensor recognizes harmful acids by detecting the corrosion of a sacrificial layer. Therefore, a prototype was constructed which uses lead as sacrificial layer and also enables a change of the sensor during the operation of the engine. The sensing element was designed that two different sacrificial layers can be used simultaneously. The prototype was evaluated in laboratory experiments to verify the temperature dependency and function during an artificial oil alteration. The used lead responded to the harmful acids in the oil. With the corrosion sensor, it is possible to reduce the maintenance cost of a biomass engine and so reduce the costs for energy processed via biomass.
