We adopt advanced precision displacement sensor production technology for manufacturing. The key components and main raw materials in the product are imported from countries such as Japan and the United States. The product testing instruments and key production equipment are imported from countries such as the United States, the United Kingdom, and Japan, ensuring excellent internal quality of the product. It has excellent performance such as linear precision, theoretically infinite resolution, smoothness, low dynamic noise, and long mechanical life.

Function and principle:
The function of an angular displacement sensor is to convert the mechanical displacement of the angle into an electrical signal. To achieve this effect, the variable resistor substrate is usually placed at the fixed part of the sensor, and different resistance values are measured by the displacement of the electric brush on the resistor substrate. The sensor slide rail is connected to a steady-state DC voltage, allowing small currents of microamperes to flow. The voltage between the brush and the output terminal is proportional to the angle at which the brush slides over the resistor substrate. Using sensors as voltage dividers can minimize the requirement for accuracy in the total resistance of the resistor substrate, as changes in resistance caused by temperature variations will not affect the measurement results.
