Abstract

PURPOSE: To obtain a sensor featuring the high resistance to the external noise and high accuracy of the working temperature by masking the thermocouple strand which is stored with electric insulation into the metal sheath connected to the engine with the metal braid wire.
CONSTITUTION: Heat contact 1 of the thermocouple plus strands 2 and 2' are stored into the metal sheath, and the electric connection is secured between strands 2 and 2' via twisted line type lead wires 5 and 5' plus joints 4 and 4' of the same material each. In addition, wires 5 and 5' are masked electrically via metal braid wire 6, and other ends 7 and 7' of wires 5 and 5' are used as the input ends of electronic switch unit 8. Then the earth wire 9 of unit 8 is connected to earth side electrode 12 of automobile battery 11 via earth terminal 10 and furthermore to engine earth contact 14 via earth bus 13. And wire 6 is connected to wire 9 and at the same time insulated from sheath 3. As a result, no closed loop is formed with the earth wire, thus preventing the electromagnetic induction noise and the abnormal voltage drop due to the earth current.
