Introduction: Recently, Beijing Fanhua Hengxing Technology Co., Ltd. (Abbreviation: Fanhua Hengxing) has launched an automatic calibration and testing system for tilt sensors, which can achieve high-precision flow calibration and testing of tilt sensors.

The system is mainly used for the detection of a single-axis tilt sensor, which can realize the synchronous test of 24 DUTs. The system provides stable tilt angle control and accurate angle feedback through a high-density mechanical structure, servo control unit and circular grating. By detecting the feedback angle of the device under test, analyze the linearity to determine whether the device under test is qualified. Inclinometer Sensor Automated Calibration and Testing System The automatic calibration and testing system for the tilt sensor is based on the “Flexible Test” technology, and fully demonstrates the technical capabilities of the system, the mechanical structure, and the software. Compared with the traditional tilt sensor test equipment, this equipment is an automated test system with high accuracy. The system's positioning accuracy is less than 0.001°, and the rotation angle feedback accuracy can reach 0.007°. At the same time, the system adopts a modular design, which facilitates the removal and replacement of fixtures and test benches. It can not only install corresponding test modules according to the needs of customers, but also provide a humanized test experience from the perspective of cost.

The mechanical structural design of the system is a major highlight of the product. Test benches, marble platforms, rotating spindles, pegboards, fixtures and drag chain structures ensure the overall accuracy of the system from design selection to machining and assembly. . The maximum indexing error of the spindle is 26.5 ", and the angle between the installation of the device under test and the vertical line is less than 0.1 °, which ensures the high precision of the mechanical structure of the system. At the same time, the automatic calibration and testing system of the tilt sensor automatically The system also has fast and stable servo motion control, calibration feedback, parallel testing in colleges and universities, flexible software configuration and other functions. The system's modularity and hardware and software structure design, and laid a foundation for the system's high scalability.
