Performance characteristics:

1. The sensor electric detection table is the length measuring standard and motion executing mechanism of the device. It mainly consists of a reference linear guide, a transmission mechanism, a stepper motor, a precision grating ruler, a fixture, and a base. The data output cable of the grating ruler on the electric detection platform, the servo motor drive cable, is connected to the electronic measurement and control box. The electronic measurement and control box is connected to the computer via Ethernet.

2. The reference linear guide adopts imported high-precision linear sliding guide as the reference for linear navigation. There are two sliders above. Install the sensor movable head fixed seat on the slider on the right. On the left slider, install a sensor fixing fixture to clamp and fix the sensor.

3. Imported precision grating ruler is used as the displacement standard, with the grating ruler reading head installed on the side of the slider on the right and the grating ruler installed on the base. When the slider on the right moves, the reading head reads the distance moved by the sensor's movable head from the grating ruler.

4. The transmission mechanism consists of a precision ball screw and another transmission linear guide, powered by a stepper motor. Form a complete integrated transmission linear module. The linear module is installed parallel to the main guide rail, driving the movable slider on the reference linear guide rail to move.

5. The servo motor provides power, and the stepper motor is connected to the precision ball screw in the linear module through a coupling.

6. Fixtures are used to fix various types of displacement sensors, with the center of the fixture aligned with the center of the probe mounting seat.

7. Able to automatically perform calibration work. After setting the calibration range, sensor model, number and other parameters, click the "Calibration" button to control the electric detection table of the line displacement sensor to automatically perform calibration work according to the specifications.

8. Automatically detect the calibration points of the forward and reverse strokes for three cycles, and can automatically collect the displacement of the electric detection table standard device and the output data corresponding to the line displacement sensor. Automatic forward and backward movement, smooth operation, accurate positioning. Automatically read data, automatically record detection data,.

9. Automatically calculate and process detection data. Be able to calculate the reference line equation according to the calibration specifications. Obtain the sensitivity, basic error, linearity, return error, repeatability and other results of the sensor

10. Automatically generate reports and output calibration results. Capable of automatically generating calibration raw records. It can be saved to the database and queried by sensor model, number, detection date, and other conditions. Can be printed by a printer. It can be exported to Excel spreadsheets and PDF files. Calibration certificates can be automatically generated.

11. The device standard can perform linear compensation and segment compensation.
