(1) Electronic ruler
When the electronic ruler is used to a certain moment, in the face of aging problems, we should pay attention to it, if the seal is now aging, and there are many impurities, water mixture and oil, then it will affect the touch resistance of the brush, resulting in the continuous beating of the displayed numbers, then we need to replace the electronic ruler, which has been damaged and can only be replaced.
(2) The power supply capacity is small
What are the problems with the small power supply capacity of displacement sensors? The movement of the melt will change the appearance of the clamping electronic ruler and shake it, or the movement of the clamping will shake the appearance of the injection electronic ruler, resulting in a big error in the measurement results. Therefore, the power supply must have sufficient capacity to avoid errors in measurement results.
(3) Disturbance
Frequency modulation and electrostatic interference will cause the sensor's electronic ruler to show digital jumping, and the signal line of the electronic ruler should be separated from the strong electrical line of the equipment. The enclosure should be mandatory with a grounding bracket and excellent contact between the enclosure and the ground. In addition, the signal wire should be shielded wire, and a section of the electrical box should be grounded with the shielded wire. If you encounter static electricity disturbance, you can use a section of power cord, the cover screw of the electronic ruler and some metal on the machine to connect it. If you encounter high-frequency disturbance, you can try to verify it by stopping the high-frequency power saver or manipulator.
(4) There is no visible data
When the electronic ruler does not show data during operation, or the display data at a certain point has a regular jump, then we need to check whether the insulation of the connecting wire is damaged, and the short circuit to the ground caused by regular contact with the shell of the machine.

Classification of rotary encoders
There are two main types of encoders, incremental encoders and affirmative encoders. The incremental encoder reads the change in the viewpoint displacement, while the affirmative encoder reads the positive viewpoint of the encoding axis. They are done using three common skills, i.e., optical, mechanical, or magnetic.

Features of potentiometer torque transducers – Beggarb
Torsion bar torque transducer is mainly composed of torsion bar tension spring, rotation-displacement converter, and potentiometer. The main function of the torsion bar tension spring is to detect the torque of the driver acting on the steering wheel and convert it into the corresponding corner value.
The angle-displacement converter is a pair of spiral mechanisms that stretch the torsion bar.
