High precision TTP with
stylus module changing
The TP200 was developed for tightly toleranced workpieces,
ａnd where access to features requires long or complex stylus
arrangements.
High precision repeatability and 3D form measurement with
long styli is achieved by employing a novel type of strain
gauge structure to detect small displacements of the
stylus tip.
In standard probes, where a mechanical switch generates the
touch signal, the force required at the stylus tip to trigger the
probe varies with the probing direction, producing small form
measurement errors sometimes called ‘lobing’. The TP200
overcomes this error by using electronic strain sensing to
precisely detect the force produced by minute displacements
of the stylus tip.
The TP200 system incorporates a probe body and separate
stylus modules, providing rapid stylus changing and probe
overtravel capability, and is compatible with Renishaw’s probe
heads and extension bars.
