PROBLEM TO BE SOLVED: To obtain an inexpensive hybrid sensor for rotating speed/temperature for vehicle with excellent workability by providing such a structure that includes a hybrid sensor provided with a means for converting five-terminal to three- terminal, a means for detecting rotating speed/temperature signals. SOLUTION: A voltage VB is supplied to the input side of a constant voltage means 8 from the input-side terminals T11 and T15 of a means 3 for converting five-terminal to three-terminal. The means 8 generated a constant voltage VC and supplies it to a rotating speed sensor 5, a waveform shaping means 7, and a temperature sensor 5 respectively. The means 3 outputs a rotating speed signal SV inputted to a terminal T12 and a temperature signal SV that a temperature signal STO inputting into terminals T13 and T14 is amplified by an amplifying means 10, to an adding means 9 for addition, and the addition output is outputted as a hybrid signal SVT of rotating speed/temperature to the output-side terminal T02 . Five terminals are needed to process and transfer the rotating speed signal and temperature signal as well as to supply an electric power, however, three terminals are enough to process them thanks to the means 10 and 9. |
