ABSTRACT:
A probe system includes a probe head and a transceiver element. The probe head has a feeler and a sensor element. Moreover, the probe head is able to be transferred from a passive state to an active state, a sensor signal being able to be generated by the sensor element in the active state. The probe head and the transceiver element are configured such that a wireless data transmission is possible between them in a manner that the sensor signal is convertible in the probe head into a switching signal which is transmittable from the probe head to the transceiver element. During the active state, a control command is able to be transmitted continuously in wireless fashion by the transceiver element, the active state of the probe head being able to be maintained by the continuously transmitted control command. Furthermore, the switching signal is able to be transmitted without collision with respect to the transmission of the control command.
