What is an angular displacement sensor, what are its advantages and applications
The product has high sensitivity, high repeatability, nearly infinite rotation life, and good high frequency response characteristics. It has strong environmental applicability and can be used in harsh industrial environments such as water, oil, steam, dust, high and low temperature, vibration and shock. 360° absolute position measurement is an ideal product to replace optical encoders, resolvers, and conductive plastic potentiometers. It can measure some angles that are not easy to measure directly in practice by measuring a series of easy-to-measure physical quantities such as resistance, capacitance, voltage, etc., for example, angles with extremely small values, extremely large angles, or angles with extremely high accuracy requirements. This solves many difficulties in measuring angles in practice.
The electronic component that uses the angle change to locate the object position is the angle displacement sensor. At present, angular displacement sensors are widely used in the servo systems of automobiles, construction machinery, space devices, missiles, aircraft radar antennas, and injection molding machines, woodworking machinery, printing presses, electronic rulers, robots, engineering monitoring, computer-controlled sports equipment, etc., which require precise measurement of displacement In the field. Its accuracy and reliability are directly related to national defense construction and engineering construction.
According to the nature of the target, the targets detected by the angular displacement sensor are divided into real-time changing and static targets. The static angle measurement technology has basically matured. However, the precise measurement technology of dynamic angle is not perfect, and there are many problems, which is a hot research topic now. With the development of national defense technology, higher-level requirements have been put forward for the accuracy of angle testing. Therefore, future research will develop towards high accuracy, high reliability, no absolute zero, high anti-interference ability, and low cost.
