| 1. A probe system, comprising
a probe head including a feeler and a sensor element, a state of the probe head changeable from a passive state to an active
state, the sensor element, in the active state, configured to generate a sensor signal as a result of contact of the feeler
with a workpiece; and
a transceiver element;
wherein the probe head and the transceiver element are configured for wireless data transmission with each other;
wherein, in the active state, the sensor signal is convertible in the probe head into a switching signal transmittable in
wireless fashion from the probe head to the transceiver element;
wherein the transceiver element is configured to continuously, wirelessly transmit, during the active state, a control command
to maintain the active state of the probe head, the active state of the probe head triggered by reception of the control command
by the probe head; and
wherein the switching signal is transmittable without collision with respect to the transmission of the control command.
