Automatic calibration device for displacement sensor

Automatic calibration device for displacement sensorIt consists of three parts: displacement sensor standard device, digital multimeter, and linear displacement sensor automatic calibration software.

1. Displacement sensor standard device

This device is the actuator of the displacement sensor standard. The device is connected to the computer via a USB cable.

The device uses a precision grating displacement ruler as the standard, a precision screw and linear guide as the transmission mechanism, and a stepper motor as the power source. The base of the device is made of cast iron material and has undergone natural aging treatment.

The measuring head is used to fix the sensor measuring rod. The measuring head is installed on the slider. The grating ruler adopts an imported open grating ruler.

2. Digital multimeter

A displacement digital meter is a secondary instrument device that collects electrical signals from displacement sensors and converts them into digital quantities. The digital quantities are uploaded to a computer through a communication interface. The device needs to be able to interface with various types of linear displacement sensors and convert signals such as voltage, current, pulse, frequency, etc. Can provide excitation signals for displacement sensors.Automatic calibration device for displacement sensor

3. Automatic calibration software for linear displacement sensors

This software complies with the national calibration standard JJF 1305-2011 "Calibration Specification for Linear Displacement Sensors". It can also be calibrated according to user-defined specifications. Main functions:

(1) Capable of automatically collecting displacement data from standard devices and collecting physical data from linear displacement sensors.

(2) Capable of calculating fitting equations according to standard requirements and displaying the true error curve.

(3) Capable of automatically performing calibration work. After setting the calibration range, calibration interval and other parameters, click the "Calibration" button to automatically calibrate according to the specifications and generate calibration data.

(4) Calibration data can automatically generate calibration raw records. It can be saved to the database and queried based on conditions. It can be printed to a printer. It can be exported to Excel spreadsheets and PDF files. Calibration certificates can be automatically generated.

(5) The device standard can perform linear compensation and segment compensation.

Technical indicators:

1. Measurement range: Effective measurement range: 0-100mm, 0-600mm, 0-1000mm.

2. Resolution: The digital resolution can be adjusted to 1um, 2um, or 5um (the highest resolution can reach 0.1um);

3. Displacement positioning accuracy: Conventional 1um, 2um, 5um, and the highest can reach 0.1um;

4. Accuracy: higher than the requirements of the national calibration standard JJF 1305-2011 "Calibration Specification for Linear Displacement Sensors".
