PROBLEM TO BE SOLVED: To precisely detect displacement, independently of the variations in the temperature environment surrounding a displacement sensor, and to realize reduction in the size of the sensor. SOLUTION: A primary coil 32 is wound around the outer of a bobbin 30. A secondary coil 34 is wound coaxially with the primary coil 32. A sensing core is provided movably in the bobbin 30. A sensing body 38, having a temperature coefficient of resistance equal to the secondary coil 34, is installed on the outer circumference of the bobbin 30. COPYRIGHT: (C)2005,JPO&NCIPI
