TIRE MONITORING SENSOR

摘要: PURPOSE:To make it possible to detect the phenomena concerning a tire by compact, light-weight, inexpensive sensor without power source, combining piezoelectric element and transmitter, which transmits voltage pulses generated in element, through an elastic body, embedding them tire. CONSTITUTION:A monitoring 1 comprises 3 or combined body of mass 5, amplifies deformation element; transmitter 6, voltages 3. Both parts are electrically connected 7. The is embedded outer surface 8, with tip 5 directed outward. At time normal rotation, output 9 constant interval converted into electromagnetic wave 6 displayed on display device vehicle, when rotation started. When pressure decreased, peculiar 10 displayed. abrasion reaches limit, extremely high 11 Thus, can be detected compact at low costs source.
