What are the reasons that affect the accuracy of the cable displacement sensor?
In the process of measuring the cable displacement sensor, the impact of accuracy is very important. Many users don't know the reasons. Today I will explain it to you. I hope users can use it in future work:
1. The frequency of the pull-wire displacement sensor determines the accuracy of the measured object. The selection of the corresponding frequency must be selected within the scale of the practical measurement, but in the practical application of the displacement sensor, all products will have a certain signal delay. The faster the small signal transmission rate. For example, due to the influence of its structure, the rope displacement sensor has determined its frequency response speed, and in terms of mechanical structure, the inertial impact of the tension spring causes a decrease in the signal frequency.
2. The linear scale of the cable displacement sensor refers to the scale whose output is proportional to the input. The sensitivity remains constant within the theoretical scale. The wider the linear scale of the sensor, the larger the range, and a certain measurement accuracy can be ensured. When selecting a displacement sensor, when the sensor's variety is confirmed, the first thing to do is to see whether its range meets the requirements. However, in practical applications, no sensor can guarantee a certain linearity, and its linearity is also relative. When the required measurement accuracy is relatively low, within a certain scale, the sensor with less nonlinear error can be approximately regarded as linear, which will bring great convenience to the measurement.
The above two points are the reasons that affect the accuracy of the cable displacement sensor. In the specific measurement process, it must be based on the actual operation. The reason for the accuracy is not necessarily the two mentioned by the editor. There are other reasons.
