Abstract

The invention relates to a high-precision angular displacement sensor; a limit screw (2), a signal plate (4), an amplification plate (6) and a corresponding device (10) are arranged on a base (5); a lead passes through the base (5) and connects the signal plate (4) with the amplification plate (6); a bearing (7) and a shaft sleeve (8) are arranged on a spindle (1); a left end cover (3) and a right end cover (9) are respectively arranged on the left end and the right end of the base (5); the spindle (1) passes through the base (5) and is connected with a rotor on the corresponding device (10); an O-shaped ring (11) is arranged between the spindle (1) and the left end cover (3); the middle part of the spindle (1) is provided with a sector bulge; the position of the limit screw (2) is to the opposite of that of the sector bulge on the spindle (1); and a lining (12) is arranged in a hole in the right end cover (9). According to the sensor, the sensitivity is high, the measurement precision is high, the power consumption is low, the environment adaptability is strong, and the temperature drift is effectively suppressed.

Description

[0001] technical field [0002] The invention relates to a sensor, in particular to a high-precision angular displacement sensor. Background technique [0003] Angular Displacement Transducer is a type of Displacement Transducer with non-contact design, which effectively improves long-term reliability compared with other traditional angular displacement measuring instruments such as synchronous analyzers and potentiometers. With the development of society and technology, users have higher requirements on the accuracy and sensitivity of angular displacement sensors. [0004] At present, there are many kinds and sizes of angular displacement sensors on the market, and they have a wide range of applications, but the main problems are as follows: 1. Low precision and high power consumption; 2. Low sensitivity, the output cannot follow the change of the input better; 3. The adaptable temperature range is small, the durability is poor, and it is easily affected by the environment...
