Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further.
By Fig. 1-Fig. 2 as seen, the below of Hall integrated circuit 1, be provided with the magnetic conduction signal of several teeth fluted disc 6 is arranged on the excircle, leave a gap 7 between Hall integrated circuit 1 and the magnetic conduction signal fluted disc 6, Hall integrated circuit 1 is by four pin S1, S2, S3, S4 inserts one by capacitor C 1, capacitor C 2, and diode D1 forms interface circuit 2, a capacitor C 1 in parallel connects power supply between pin S1 in the Hall integrated circuit and the ground, the S2 output signal is delivered to the output terminal 4 of interface circuit 2 through diode D1, S3 ground connection, S4 capacitor C 2 ground connection of connecting.
When using the utility model, need between the positive source 3 of interface circuit 2 and earth terminal 5, connect the 14V direct supply, below Hall integrated circuit 1, being provided with has the magnetic conduction signal of several teeth fluted disc 6 on the excircle, leave a gap 7 between Hall integrated circuit 1 and the magnetic conduction signal fluted disc 6.When magnetic conduction signal fluted disc 6 rotates, formed the air-gap field of alternation between Hall integrated circuit and the signal fluted disc 6, the pin S2 of Hall integrated circuit 1 has exported signal thus, deliver to the output terminal 4 of interface circuit 2 through diode D1, what this end was exported is that magnitude of voltage is constant, frequency is passed to checkout equipment to this signal with the square-wave signal of fluted disc rotation speed change, just can obtain the size of the rotating speed of fluted disc.
