Abstract:
     The present invention relates to a sensing method of on-site quick surface roughness measuring instrument. Its belonged technical field is "surface roughness determination". It is mainly used for solving the problem of that production site is short of "surface roughness measuring instrument" in the existent technique. Its main technique is characterized by using a determined part surface to build up capacitance (capacitive reactance) so as to implement sensing. The on-site quick surface roughness measuring instrument made by use of said method has the rapid measurement speed and high accuracy, and is mainly used for detecting a part "surface roughness" in situ.
