New Product: Battery-Free Touch Probe
The TS 444 infrared touch probe can be powered by compressed air supplied through a machine-tool spindle.
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.
