The probe module
Each probe module houses the touch-trigger mechanism that carries the stylus assembly. The module provides overtravel in the X, Y and Z
axes. The M2 stylus mounting is compatible with Renishaw's comprehensive range of M2 styli.
Electrical contact pins automatically complete the probe circuit.
TP20 module selector
Seven versions of the TP20 probe module can be used with the RTP20, they can be identified by the end cap colour.
1. Low force (LF) probe module (green cap)
2. Standard force (SF) probe module (black cap)
3. Medium force (MF) probe module (grey cap)
4. Extended force (EF) probe module (brown cap)
5. 6-way (6W) probe module (blue cap)
6. Extension module 1 standard force (EM1 STD) (black cap)
7. Extension module 2 standard force (EM2 STD) (black cap)
Medium and extended force modules are used to overcome the effects of false triggers, caused either by stylus length and mass, or
vibration caused by machine acceleration forces.
The low force module permits the measurement of delicate objects.
The EM1 and EM2 extended modules allow access to otherwise inaccessible workpiece features. Both operate using standard force and
offer better measuring performance than using long styli with SF, MF, LF or EF modules.
The TP20 6-way senses in the +Z and -Z directions, allowing undercuts to be checked.
