The measurement accuracy of the rebound displacement sensor is crucial to its application in industrial manufacturing, building monitoring and other fields, and many factors will interfere with its measurement accuracy.
Environmental factors are a key factor affecting measurement accuracy. Temperature changes will cause the internal components of the rebound displacement sensor to expand and contract, thereby changing the size and performance of the mechanical structure and affecting the accuracy of displacement measurement; in an environment with high humidity, the electronic components of the rebound displacement sensor may malfunction due to moisture, resulting in abnormal signal transmission, which in turn causes deviations in the measurement results; in an environment with strong electromagnetic interference, the signal of the rebound displacement sensor is easily interfered with, resulting in signal distortion or noise, affecting signal processing and analysis, and ultimately resulting in reduced measurement accuracy.
The mechanical installation link should not be underestimated either. During the installation process, if the connection between the rebound displacement sensor and the measured object is not firm, the rebound displacement sensor may become loose or displaced during the movement of the object, resulting in the measurement data not matching the actual displacement; improper installation position selection causes the rebound displacement sensor to bear additional external force or torque, which will affect the internal sensitive components, change its normal working state, and reduce the measurement accuracy; at the same time, inadequate calibration during installation will cause errors in the initial measurement benchmark of the rebound displacement sensor, resulting in systematic deviations in all subsequent measurement data.
The structure and material properties of the rebound displacement sensor itself will also affect the accuracy. The unreasonable design of the mechanical structure inside the rebound displacement sensor, such as the unstable elastic coefficient of the rebound mechanism, will cause the rebound displacement sensor to have nonlinear errors during the measurement process; the material performance of the rebound displacement sensor is not good, such as the short fatigue life of the elastic element and the poor stability of the electronic component. As the use time increases, the material performance gradually deteriorates, which will directly affect the measurement accuracy; in addition, the manufacturing process accuracy of the rebound displacement sensor is insufficient, and the processing errors of the internal parts will further accumulate after assembly, reducing the overall measurement accuracy of the rebound displacement sensor.
The operating specifications during use also affect the accuracy. Frequent and excessive use of the rebound displacement sensor beyond its rated operating range will accelerate the wear and aging of the internal components of the rebound displacement sensor, shorten the service life of the rebound displacement sensor, and reduce the measurement accuracy; during operation, if the measurement is not performed according to the prescribed process, such as the measurement speed is too fast or too slow, the response of the rebound displacement sensor may not keep up with the actual displacement change, resulting in inaccurate measurement data; and, if the rebound displacement sensor is not cleaned and maintained regularly, dust, oil and other impurities will adhere to the surface of the rebound displacement sensor or enter the interior, which will affect the normal operation of the rebound displacement sensor and interfere with the transmission and processing of the measurement signal.
The characteristics of the measured object are also an important aspect that affects the measurement accuracy. If the surface of the measured object is uneven or contains impurities, the measuring contact of the rebound displacement sensor may not be able to accurately obtain the real displacement information when it contacts the object, resulting in errors in the measurement results; the materials of the measured objects are different, and their physical properties such as elastic modulus and hardness are also different, which will affect the interaction force between the rebound displacement sensor and the object, and thus affect the accuracy of the measurement; in addition, the vibration and impact of the measured object during movement will cause the rebound displacement sensor to be subjected to additional dynamic forces, causing fluctuations in the measurement signal and affecting the measurement accuracy.
The signal transmission and processing links should not be ignored either. During the transmission process of the signal output by the rebound displacement sensor, if the transmission cable quality is poor or the line is too long, the signal will be attenuated and distorted, resulting in differences between the signal obtained by the receiving end and the original signal; the design and performance of the signal processing circuit are also crucial. If there are defects in the processing links such as signal amplification and filtering, and noise and interference signals cannot be effectively removed, the accuracy of the measurement results will be greatly reduced; at the same time, the low algorithm accuracy of the data acquisition and processing software will also lead to errors in the final measurement data.
In practical applications, only by understanding these factors that affect measurement accuracy and taking targeted measures to control and optimize them can the performance advantages of the rebound displacement sensor be fully utilized and the accuracy and reliability of the measurement results be ensured.
