The TS 444 is an alternative to battery-operated touch probes for machining applications. The probe can be powered by an alternative energy source in the form of compressed air supplied through the spindle of the machine tool and can be of use with all of the company’s control systems. Compressed air is introduced into the probe via the taper shank, powering 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. With fully charged capacitors, the device is able to probe for two minutes. The charging time varies depending on the pressure: The higher the pressure, the shorter the charging time. A supply pressure of 5 bars or more is recommended to ensure that charging takes place in a reasonable time. For example, when a pressure of 5.5 bars is used, it takes approximately 3 seconds to charge the probe.
