PURPOSE: A pulse signal sensing method of a mechanical gauge and a device thereof are provided to reduce battery consumption of a sensing device and be able to sense a pulse signal more exactly regardless of kinds of pulse signals.;CONSTITUTION: A pulse signal sensing device of a mechanical gauge(100) comprises a sensing part(110), a pulse width calculation unit(120), a pulse DB(130), a sensing frequency calculation unit(140), and a controller(150). The sensing part senses a pulse signal of the mechanical gauge by predetermined cycle time. The pulse width calculation unit increases the counter number of the sensed pulse signal and computes pulse width of the pulse signal. The sensing frequency calculation unit matches the counter number of the pulse signal to the pulse width and the result of comparing with a standard value which is a predetermined counter number and computes a sensing cycle. The controller controls the sensing of the pulse signal according to the computed sensing cycle.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Sensing part; (120) Pulse width calculation unit; (130) Pulse DB; (140) Sensing frequency calculation unit; (150) Controller; (AA) Pulse signal input
