Stress sensor calibration teaching tr--ning device,Textile printing and dyeing wastewater treatment experimental device

Pressure measurement equipment is widely used in engineering, with a wide variety of types. The calibration of key components of pressure measurement equipment The calibration of pressure sensors is an important part of ensuring the accuracy of the equipment. Therefore, the pressure sensor calibration experiment is an important part of the course teaching of "Thermal Work Inspection Technology". Through this experiment, it can deepen the students' understanding of the theory of automatic detection technology, so that students can better learn this basic course of this project to understand the dynamic response characteristics of sensor dynamic response characteristics The importance and measurement and processing methods of dynamic pressure measurement. In this experimental desk, a piston static pressure power verification equipment is used at the same time to check the industrial far -pass pressure gauge and the static and dynamic pressure of the pressure sensor installed in the same pressure chamber; The above pressure sensors measure this pressure signal at the same time, and measure the dynamic characteristics of each pressure sensor. The output of each pressure sensor is collected and analyzed by the computer to deepen the students' understanding of pressure detection technology and improve the ability to use microcomputer to analyze static and dynamic performance analysis of each pressure sensor. This experimental desk is advanced technology, suitable for product quality inspection and teaching and scientific research of manufacturers.
