Abstract

The invention relates to the field of electronic components, in particular to a resistor angular displacement sensor, which comprises a base and a sealing cover, wherein the space formed by the base and the sealing cover is internally provided with an annular rotating brush support plate and an annular fixing piece; the side, close to the rotating brush support plate, of the fixing piece is provided with an opened annular resistor; a joint at one end of the opening of the resistor is connected with a wire group, the resistor is slidably contacted with a first brush; and the rotating brush support plate is in sliding contact with a second brush. The angular displacement sensor disclosed in the invention has the advantages that the effective electric stroke range is large, the whole circumference can reach 360 DEG, the linear precision is high, and pulse coded signals can be outputted at the same time.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a resistance angular displacement sensor. Background technique [0002] The angular displacement sensor is a high-precision displacement sensor whose voltage output has a functional conformity relationship with the rotation angle or linear displacement. It is often used in aviation, aerospace, weapon systems, and industrial servo controls such as aerospace devices, missiles, and aircraft. Its working principle is the principle of resistive voltage division. When working, apply positive and negative working voltages, take 0V point as the 0° base point, and move forward and reverse within the effective electric stroke range. The displacement is proportional to the output voltage, and the displacement is realized. precise positioning. In practical applications, the effective measurement range of the general angular displacement sensor is 0° to 300°, and when the resistance chan...
