Selection of wire displacement encoder , We need the guidance of precision electronics

The cable displacement encoder is a hinge part for measuring or controlling position , In mechanical equipment 、 Chemical equipment 、 Electrolytic aluminum equipment 、 River embankment survey 、 It is widely used in many fields such as industrial production line , So in the selection process, we need to understand the problem , Today, we will share with you how to choose , Pay attention to which aspects of the problem :

1. According to the measurement distance to confirm the travel of the rope displacement sensor . This depends on its own equipment on-site measurement , First, confirm the signal pattern of the requirement , This has to be combined with its own equipment control part , If you don't confirm that you can communicate with the selected control software engineer . because , There are many similar products with the same measurement displacement , In principle, it's also diverse , Select sensor manufacturers with different principles and confirm the following : The size of the range 、 What is the requirement of the main scale of the displacement sensor for the moving part of the measured object .

2. The linearity of wire encoder determines the concave and convex of sensitivity , But it's not that the higher the sensitivity, the better . This requires full integration of the output signal corresponding to the object being measured , As long as it's best for signal processing . It's the best choice . Because the sensitivity of the rope encoder is directional . When the output only requires AB When the result is not high , We have to choose products with low sensitivity .

3. Linear scale linear scale the linear scale of wire encoder refers to the scale that the output is proportional to the input . In theory , Within this scale , The sensitivity was proved to be stable . The wider the linear scale of the drawstring code , The higher the accuracy . When selecting the cable encoder , First of all, it depends on whether the measurement requirements can be met . In the process of practical measurement , There is no guarantee that any type of product is linear .

4、 In terms of service life , Due to its special mechanical structure, the cable type displacement encoder , The service life is generally in 500 Ten thousand times ~1000 Between 10000 times , However, the working efficiency and the influence of the environment will also shorten the service life of the cable displacement sensor , As in high magnetic fields 、 High pollution 、 Working under concave convex temperature environment , All of these are the reasons for shortening the life of the cable sensor .

The above points are the selection of wire displacement encoder , Something to be aware of
