The precise measurement of any detection direction by RST-P, due to the clever integration of multiple technical functions, the RST-P trigger probe is suitable for various applications, achieving precise measurement in any detection direction. This probe captures measurement data quickly and dynamically through single point detection, unaffected by needle bending and mechanical hysteresis. RST-P operates based on the duality principle. That is to say, it can transmit the actual detection pulse emitted from the piezoelectric element located in front of the knot point. Three point bearings simultaneously serve as mechanical twisting points to verify the detection results and avoid damage to RST-P due to contact and collision with the workpiece. In addition, bearings and different
