Introduction
1 Introduction
The TP200 probe system comprises the TP200 probe sensor and stylus module, the
PI 200 interface and the optional SCR200 stylus change rack.
The TP200 is a 13.5 mm diameter touch-trigger probe with the facility to quickly change
stylus configurations without the need for requalification. This is achieved by carrying
the stylus on a detachable module that is located on the probe sensor body by a
highly repeatable kinematic coupling and held in place by magnetic force. After initial
qualification of the stylus tip, the module may be removed and replaced as required
without additional requalification by simply recalling the initial qualification data.
The probe sensor uses electronic strain sensing techniques that provide better form
measuring accuracy and operating life than can be achieved with kinematic switching
probes.
The SCR200 stylus change rack provides storage for pre-qualified stylus assemblies
and facilitates automatic stylus changing under measurement programme control.
The dedicated PI 200 interface supplies power and controls the operation of the TP200
probe and SCR200 rack. Communication with other Renishaw equipment and the CMM
controller is via the PICS (product interconnection system) ports.
The TP200 system components (probe sensor, stylus module, PI 200 interface and
SCR200 stylus change rack), illustrated in figure 1, are described in the TP200 probe
system user’s guide (Renishaw part number H-1000-5014).
A version number label (e.g. V9) on the PI 200 rear panel indicates the modification
level of the unit. A summary of the changes made at each level is included later in this
document.
