Does the long-range cable displacement sensor have a long life?
How long is the service life of the large-range cable displacement sensor? Before we understand what this problem is, we must first understand the characteristics of this type of sensor. After clarifying this problem, everyone will know how long the life of this type of sensor is. Now let Jingliang Electronics editor lead you Let's go:
The large-range cable displacement sensor can be divided into incremental type and absolute value type. According to voltage output, it can be divided into voltage output, open collector output, push-pull complementary output and long-line drive output. Large range 0-50000mm pull wire displacement sensor is a kind of linear part of signal induction. After input voltage, with the movement of machinery, the inner pulley drives the rope encoder to rotate, and the signal is transmitted by the photoelectric transmitter and receiver device in the photoelectric encoder Read to obtain four groups of sine wave signals combined into A, B, C, D, each sine wave has a phase difference of 90 degrees, and the C and D signals are reversed and superimposed on the A and B phases to enhance stability Signal, output a Z-phase pulse every revolution to represent the zero reference position.
The service life of the large-range cable displacement sensor:
1. To determine the reliability of the use environment, such as the use environment is very harsh, moisture, high temperature, signal interference will affect its service life.
2. The rigidity of the coil spring inside the product. The rigidity of the spring will directly affect the life of the cable sensor, and it will cause the rigidity to drop and the cable slack after a certain period of use.
3. The tensile strength of the wire rope, the wire rope generally adopts imported plastic-coated steel wire, which is composed of more than 100 strands, as long as no external force is applied to it, there is no problem.
4. The corrosion resistance and interference resistance of the shell. The product shell is made of aluminum alloy after oxidation treatment, and the service time is more than 10 years.
5. The quality of the rotary encoder: The internal structure of the encoder is composed of glass, metal, plastic and circuits, and under normal circumstances, it has extremely strong thermal stability.
From what I have shared for everyone, we can see that the service life of a large-range cable displacement sensor does not depend on one aspect, but is caused by multiple factors. The length of the life depends on its own usage. We all share more knowledge content and look forward to your attention!
