GL3000 Sensor comprehensive experimental platform 

Ⅰ、Product Overview

The GL3000 sensor comprehensive experimental platform  is a modular new product newly launched on the basis of our company's many years of production of sensor technology teaching experimental devices to meet the professional needs of different categories and levels.

The GL3000 sensor comprehensive experimental platform is mainly used for experimental teaching of courses such as "sensor principle", "automatic detection technology", "non-electrical quantity electrical measurement technology", "industrial automation instrumentation and control", and "mechanical quantity electrical measurement" offered by major and technical colleges.

Most of the sensors used in the GL3000 sensor comprehensive experimental platform are industrial structures, which is convenient for students to strengthen their understanding of book knowledge, and in the process of the experiment, through signal pickup, conversion, and analysis, cultivate students' basic operating skills and hands-on ability as a scientific and technological worker.

Ⅲ、Product features

 1. The structure of the sensor comprehensive experimental table tends to the industrial detection sensor structure. The sensor combines qualitative and quantitative analysis with a certain degree of accuracy, which is more convenient for computer experimental characteristics analysis.

 2. The instrument is equipped with temperature source, gas source, vibration source and rotation source. The sensor is equipped with corresponding experimental templates for easy operation and management. After the experiment is completed, it can be placed in the cabinet of the experimental table and the sensor box respectively. It can add enhanced sensors and their templates according to teaching needs, or make special sensor templates.

 3. Various public sources can also be used for students' course design, graduation design and some development experiments; the power supply and signal source are equipped with protection circuits to ensure that students will not easily damage the equipment after misoperation and ensure the safety of students.
