Abstract (en)

The device has a mechanically transactional sensor unit (5), where a resistance (R1) is arranged in an isolated electric cable (1) for providing a preset resistance value during the transaction of the sensor unit. An electrical supply (3) and an electrical discharge (2) are connected with each other in an electrically conductive manner at a free end (7) of the sensor unit. Resistances (R1-R3) are arranged in the electrical supply in a row.
