The magnetic transducer is enclosed into the electronic box that houses the power supply, step motor drivers,
encoder electronics, touch sensor control and current supply for calibration tools.
Figure 28: Electronic Box
The Hall probe is mounted on a touch sensor (tactile sensor), that reacts whenever the probe touches an
object. This feature provides an effective protection from the probe mechanical damage (motion is stopped as
soon as touch sensor reacts, i.e. when the probe touches an obstacle); it also allows an absolute magnet
positioning, i.e. the precise definition of the scanning starting point; and touch sensor can be used, in
combination with an optional stylus, for the dimensional measurement of objects under tests, transforming in
that case the magnetic field mapper into easy-to-use coordinate measuring machine (CMM).
Figure 29: The Touch-trigger sensor is a mechanical device that has the ability to return the stylus ball to the same repeatable position
following any deflection. For the touch-trigger function, the probe is moved in the direction of the object under test, until it is touched.
For instructions on assembly and maintenance of the touch sensor check the Appendix.
