The TP200 system components are:
• TP200 probe body – the standard model
• TP200B probe body – a variant model with increased vibration tolerance
• TP200 stylus module – choice of fixed overtravel forces: ‘SF’ (standard force) or ‘LF’ (low force)
• PI 200 probe interface
• SCR200 stylus changing rack
TP200 probe body
The TP200 probe incorporates micro strain gage transducers delivering excellent repeatability and accurate 3D form measurement even with long styli. The sensor technology gives sub-micron triggering performance and eliminates the lobing characteristics encountered with standard probes. The solid state ASIC electronics within the probe ensure reliable operation over millions of trigger points.
TP200B probe body
The TP200B probe uses the same technology as TP200 but has been designed to have a higher tolerance to vibration. This helps to overcome the problem of ‘air’ trigger generation which can arise from vibrations transmitted through the CMM or when using longer styli with faster positioning speeds. Please note that we do not recommend the use of TP200B with the LF module or cranked/star styli.
