Abstract:
1. A non-contact measurement signal transmission system, applied to a wheeler device, wherein the wheeler device comprises a body and a rotator, and the rotator rotates relative to the body, the system comprising: a detection device, disposed on the body, for generating an alternating current (AC) signal; a first magnetic coupling device, comprising a first primary side and a first secondary side, wherein the first magnetic coupling device receives the AC signal at the first secondary side and emits a magnetic coupling signal from the first primary side; and a pressure sensing device, disposed on the rotator and electrically connected to the first primary side, for receiving the magnetic coupling signal, wherein the pressure sensing device comprises a forced portion and a base, the pressure sensing device responds and transmits a feedback signal to the first primary side according to a relative position of the forced portion and the base, and the detection device outputs a forced signal according to the feedback signal transmitted by the first magnetic coupling device.
