ことを特徴とする変位検出器。 A resistor interposed with a predetermined length between a low voltage source and a high voltage source and generating a potential on its surface that increases from the low voltage source toward the high voltage source, and a resistor in the vicinity of the resistor. A conductor that is provided and conducts electricity,
A good conductor that takes out the potential from the resistor from a predetermined output terminal, and a good conductor that slides on the resistor and the good conductor to follow the displacement of the object to be measured, and changes the potential on the surface of the resistor to the displacement of the object to be measured. Correspondingly, in a displacement detector equipped with a brush that transmits the transmission to a good conductor, a protective resistor is inserted in a predetermined part of the good conductor between the part on which the brush slides and the output terminal. displacement detector.
