As sensors are used in the diverse industrial applications this component has to fulfill a variety of requirements. This includes leak tightness against dirt and moisture, whose requirements are specified in the IP protection classes. Penetration of liquids can cause serious malfunction of the sensor and the associated electronics. Thus, the sensors have to be leak tight. The leak testing of the sensors as an end-of-line test integrated in the production line is of particular importance. The basics of leak testing and important practical aspects of the leak test process are treated.
