|Gannen-XP - ultra precision tactile probe|
The basis of the 3D Gannen probe is a silicon chip with integrated piezo resistive elements. One point probing and scanning is possible with ultra low uncertainty. The probe is lightweight with a colliding mass of approximately 34 mg. Combined with a stiffness down to 150 N/m this allows high speed measurements with probing forces down to a few micro Newtons, depending on the CMM used.
Measurements using the XPRESS probe shown a 3D uncertainty of 45 nm and a 1D repeatability of 2 nm or less (standard deviation) in any direction and over its entire measurement range.
