Abstract
A sensor electric wire that is not readily affected by external noise, and a sensor circuit that uses the same, including a first internal conductor covered by a piezoelectric material, a second internal conductor provided on the outside of the piezoelectric material, and an external shield conductor surrounding the first internal conductor and the second internal conductor, an insulating body being disposed between the first internal conductor and second internal conductor, and the external shield conductor.
Claims2
A sensor electric wire, comprising:
- a first internal conductor, an external periphery of the first internal conductor being covered with a piezoelectric material;
- a second internal conductor that covers an external periphery of the piezoelectric material;
- an insulator covers an external periphery of the second internal conductor;
- an external shield conductor that covers an external periphery of the insulator;
- a sheath is provided to cover an external periphery of the sensor electric wire;
- at one end of the sensor electric wire, a first end face shield conductor surrounding an end face of the first internal conductor and conducting with the second internal conductor;
- at the one end of the sensor electric wire, a second end face shield conductor surrounding the first end face shield conductor and conducting with the external shield conductor;
- and
- at the one end of the sensor electric wire, a cover member covering the second end face shield conductor and the sheath up to its end.
