Angle sensor for throttle valve of internal combustion engine |
摘要 |
Disclosed is a non-contact type throttle angle sensor sensing and converting angular rotation of a throttle valve of an internal combustion engine into an electrical signal. The sensor comprises a magnetic field generating element disposed on one end of a rotatable throttle shaft, a magneto-sensitive element disposed opposite to the field generating element at a position fixed relative to a throttle body and spaced apart from the field generating element, the magneto-sensitive element generating an output whose level changes with the rotation of the throttle valve shaft relative to the throttle body, a housing forming an integral part of the throttle body to accommodate the field generating element and the magneto-sensitive element, and an electrical circuit converting the output of the magneto-sensitive element into an electrical signal, the electrical circuit including a circuit adjusting the zero level and maximum level of the output of the magneto-sensitive element.
