A probe head includes a feeler, a sensor unit, a CPU, a transmitting stage and a producer of electrical energy for supplying energy to the sensor unit, to the CPU and to the transmitting stage. An electrical signal is triggerable by the sensor unit in response to a deflection of the feeler which is convertible in the transmitting stage into an electromagnetic signal. The producer of electrical energy includes a turbine having rotor disk rotatable about an axis. Magnets are mounted on the rotor disk of the turbine, which are arranged across from stationary electrically conductive windings at an axial distance. The probe head includes a voltage transformer, at the output of which an output voltage is producible, which is greater than the input voltage applied to the voltage transformer, the output voltage being used to supply energy to the transmitting stage.
