Touch-trigger touch probe TP200

CMMcompacthigh-precision

The TP200 is a high-precision touch-trigger probe with stylus module changing 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 are 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. Key benefits of the system include: •Superior measuring performance with stylus lengths up to 100 mm: TP200 is recommended for tightly toleranced workpieces and high density point taking applications. It is also suited to features requiring long or complex stylus arrangements. •Increase productivity: Fast, automatic stylus changing and stylus module life typically in excess of 10 million triggers, increase productivity, saving time and costs. •Rapid and easy exchange of styli with a one-off qualification: Allows optimisation of stylus arrangements, dealing with conflicting requirements such as feature access, surface finish and accuracy.
