INOBALT contact and vibration sensors di-kus® respond to vibrations or contact of an object on the sensor contact face. This unique sensor was developed to detect small parts of 0.3 g upwards. The application fields are complex e. g. reliable hail detection on roofs or solar systems till counting applications in the screw production. A sturdy metal casing together with a high- strength baffle plate and the high protection class characterise these contact and vibration sensors.
