New Product: Battery-Free Touch Probe

The TS 444 infrared touch probe can be powered by compressed air supplied through a machine-tool spindle.
Feb. 21, 2008

The compressed air is fed into the probe via the taper shank and powers a turbine wheel inside the probe. The turbine wheel generates electrical energy through changes in the magnetic field, which is stored in high-power capacitors.

Fully charged, the probe works for 2 min. Charging time varies depending on the pressure: The higher the pressure, the shorter the charging time. To ensure charging takes place in a reasonable amount of time, a supply pressure of 5 bars or more is recommended. Air exiting the probe cleans the probing point. The TS 444 features an optical sensor that generates the trigger signal. This sensor endures a probing accuracy of ±5 μm and a repeatability of 2σ ≤ 1 μm.
