Abstract
The present invention is directed to a potentiometer having enhanced reliability and durability, capable of being unlimitedly used in a high-temperature environment inside a flying object (air vehicle). Said potentiometer comprises: a consecutive type potentiometer having a structure that a resistor is formed of a material having an excellent stability in a high-temperature environment, and having an excellent surface hardness so as to have a high resistance to damages; and a discrete type potentiometer having a structure that a resistor is protected by a passivation layer, and through holes are formed at the passivation layer for electrical connection with the outside, and the through holes are filled with a conductive material.

A potentiometer, comprising:
- a base substrate;
- a resistor formed on the base substrate, and connected to electrodes so as to form a resistance;
- a passivation layer configured to cover at least part of the resistor, and having through holes formed to be spaced from each other along the resistor such that the resistor is partially exposed to the outside at intervals;
- contact members disposed in the through holes, respectively, and electrically connected to the resistor;
- and
- a conductive brush formed to be movable with an object to be sensed and disposed to contact the contact members, so as to generate an electrical signal for calculating a position of the object to be sensed.
A flying object, comprising:
- a body having an actuator;
- and
- a potentiometer connected to a moving member which moves with interworking with the actuator,
- wherein the potentiometer comprises:
- a base substrate;
- a resistor formed on the base substrate, and connected to electrodes so as to form a resistance between the electrodes;
- a passivation layer configured to cover the resistor, and having through holes formed to be spaced from each other along the resistor such that the resistor is partially exposed to the outside at intervals;
- contact members disposed in the through holes, respectively, and electrically connected to the resistor;
- and
- a conductive brush formed to be movable with an object to be sensed and disposed to contact the contact members, so as to generate an electrical signal for calculating a position of the object to be sensed.
