| 摘要 |
An actuator rod position indication device is described, where a unit having a separate enclosing housing on one surface of said housing has mounted a magnetic field sensor, such that a magnet provided on an actuator rod's free end will be moved substantially linearly closer to and further from said sensor during operation of the actuator, where the sensor detects the magnetic field strength between the magnet on the actuator rod and the sensor and uses this information as input in a processor, comprising a storage, in which storage pre-defined activation values are stored, such that when the input corresponds to one of the stored values, an output specific to that value is generated.
