説明

The trial design and manufacture have been made for a transducer useful to measure the surface roughness. For this purpose a slender beam was set. This was soldered on a piano wire it the center of gravity as shown in Fig. 1., in order to give an oscillating motion to the stylus. The stylus was fixed on an end of the beam oscillating around the Piano wire with its natural circular frequency ω.<BR>When a test piece was put under the oscillating stylus and touched to it, the phase of the oscillation changed abruptly and led to the original phase by an amount of phase angle φ.Where φ was a function of the situation of the test piece. Then by measuring φ (Pulse Time Modulation) the situation of the test piece could be detected.
