SG1-80-3

Position sensors are capable of detecting the position of a target object, usually with high accuracy and repeatability. The SG1-80-3 is a type of position sensors. This article provides a comprehensive introduction about the application field and working principle of SG1-80-3.

Application Field of SG1-80-3

The SG1-80-3 position sensor is used to measure the angle, linear position, and displacement of an object. It is suitable in applications that need high accuracy and repeatability, such as robotics, machine tools, and automation equipment. It is also used for precisely controlling the movements of a rotary actuator, and for detecting the position of a valve or robotic arm.

Features of SG1-80-3

The SG1-80-3 position sensor has many desirable features, including high accuracy, repeatability, and sensitivity. It is able to measure the position of an object with a resolution of up to 1 arc second, and its accuracy can reach up to 0.0025 degrees. The SG1-80-3 also has a high signal to noise ratio, which ensures a reliable measurement signal even in difficult environments. Furthermore, it is resistant to shock, vibration, and extreme temperatures.

Working Principle of SG1-80-3

The SG1-80-3 position sensor exploits the principle of eddy current sensing. It generates a quantitative rotational signal from a rotating component. A permanent magnet mounted on the rotating part of the device generates a magnetic field. This magnetic field induces eddy currents in the sensor coil. As the rotor rotates, the eddy current produces a signal which is proportional to the angular position of the rotor, and this information is then converted into a voltage signal. The output voltage is directly proportional to the rotor’s angular displacement.

The SG1-80-3 also relies on waveform recognition algorithms to enhance its performance. This algorithm is applied to the digitized position signal. By comparing the signal’s waveform to that of a reference waveform, the sensor is able to determine the angular position even in the presence of interference. The SG1-80-3 also uses a temperature compensation algorithm to improve its accuracy at different temperatures. By relying on these features, the SG1-80-3 can operate in a wide range of temperatures from -40°C to +120°C.

Conclusion

The SG1-80-3 is a position sensor used for measuring angle, linear position, and displacement. Its features include a high accuracy, repeatability, and sensitivity, as well as shock and vibration resistance. The SG1-80-3 exploits the principle of eddy current sensing and relies on waveform recognition algorithms for optimal performance. It is suitable for applications that require high accuracy measurements and is a reliable solution for precise control in robotics, machine tools, and automation equipment.
