How to judge the performance of displacement sensors

During the use of displacement sensors, it is inevitable to encounter difficulties in choosing the model and brand. With years of experience in the industry, Guangzhou Zhongxin Automation Technology Co., Ltd. has summarized the following aspects for customer reference, hoping to help customers judge the performance problems encountered during use.
The performance of displacement sensors can be judged from the following aspects:
1、 Determine the type based on the measurement object and environment

Firstly, carefully analyze the measurement work and consider which principle of displacement sensor to use for measurement, as even measuring the same physical quantity can be achieved through different principles. Secondly, it is necessary to consider the range, volume (whether space is sufficient), installation method, signal type (analog or digital signal), measurement method (direct or indirect measurement), and so on.

2、 Accuracy

The accuracy level of displacement sensors is related to the accuracy of the entire system and is a very important parameter. Generally, the higher the accuracy, the more expensive the price. So when we choose, we need to consider the overall situation, and what suits us is the best. Don't blindly pursue so-called high accuracy, unless in situations where precise values need to be measured quantitatively, we only choose displacement sensors with higher accuracy levels.

3、 Sensitivity selection

Sensitivity refers to the ratio of the increment of output to the corresponding increment of input. We need to have a correct understanding of this parameter, which can be divided into two aspects:

1. In the linear range, high sensitivity and relatively large output signal value are advantages.

2. High sensitivity, external noise unrelated to measurement is also easily mixed in, which affects accuracy during processing.

4、 Linear range

Linear range refers to the range where the output is proportional to the input, so we all hope that the wider the linear range, the better. The wider the linear range, the larger the range, and the higher the accuracy. But the linear range of any displacement sensor is relative. We only need to estimate the measurement quantity to be within the linear range.

5、 Frequency response characteristics

During the measurement process, there is always a certain delay in the output of the displacement sensor, which also differs from the actual value. So we hope the frequency response is faster, so the delay time is shorter. However, due to the influence of structural and other characteristics, the frequency is also difficult to increase.

6、 Stability

Stability refers to the ability of its performance to remain unchanged after prolonged use. The factors that affect stability, in addition to their own reasons, are mainly environmental factors. Therefore, the selected displacement sensor should have strong environmental adaptability, and protective measures should be taken when appropriate.
