The TP200 Touch Trigger Probe offers outstanding metrology performance and boasts a compact design. Compared to kinematic touch-trigger probes, it uses modules and strain-gauge mechanisms for higher accuracy and longer life.
The TP200 has a long list of features and benefits that any user can enjoy. Some of the most notable ones include the following: strain-gauge technology (which offers excellent repeatability and precision 3D form measurement), zero reseat errors, no lobing effect, 6-way measuring capability and a stylus reach of up to 100 mm (GF styli).
THE TP200 SYSTEM IS COMPRISED OF THE FOLLOWING:
- TP200 or TP200B probe body (the TP200B is a variant 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
The TP200 system also has an EO (extended overtravel) module. This has the same overtravel force as the SF but provides increased operating range and protection in the probe Z axis.
The TP200 probe uses micro strain gauge transducers. As a result, excellent repeatability and accurate 3D form measurement can be experienced - even with long styli.
The unique and advanced sensor technology gives sub-micron repeatability and eliminates the lobing characteristics encountered with kinematic probes. Furthermore, the solid state ASIC electronics within the probe ensures reliable operation over millions of trigger points.
TP200 / TP200B PROBE BODY
The TP200B uses the same technology as TP200 but has been designed to have 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 long styli with faster positioning speeds.

TP200 STYLUS MODULES
The stylus module is mounted on the TP200/TP200B probe body; this is done through a highly repeatable magnetic kinematic joint that provides a rapid stylus changing capability and probe overtravel protection.
There are three modules available with the TP200 (Standard Force, Low Force and Extended OverTravel). Two different overtravel forces are also available.
| Module | SF (standard force) | LF (low force) | EO (extended overtravel) |
| Application | General use. | Small diameter stylus balls or where minimum force is essential. | Extra overtravel to enable the CMM to stop safely from higher probing speeds. |
| Comments | Styli up to 100 mm long and ball diameter > 1 mm. | Balls less than 1 mm diameter. | Same overtravel force as SF. Extra 8 mm of overtravel in probe Z axis. |
SCR200 CHANGING RACK
The SCR200 can change up to six TP200 stylus modules. It is powered by the PI200 (a separate probe interface) and provides features to enable safe stylus changing.
The SCR200 is available in low force and standard force kits. Each kit is comprised of one SCR200, plus three stylus modules of the same force.
