What are the knowledge points related to instruments?
Thread Content
I’m having training sessions every day on instruments, but I don’t know what exactly is covered or which aspects are important. I hope everyone can help me out
Bro, are you a fresh graduate? I posted a similar thread before; a senior suggested that I look at the instrument technician question bank, and I’m working on it now.
As I understand it: temperature, flow rate, level, pressure – there are many specific categories in total
The knowledge related to instruments is quite extensive. On-site instruments can be classified by type into measuring instruments and control instruments; by the power source they use, they can be divided into pneumatic, electric, and hydraulic instruments. Based on the control system used, they can be categorized as conventional instrument control or DCS (PLC) control. According to the quantities they measure, they include thermal quantities (temperature, pressure, level, flow rate), electrical quantities (voltage, current, power, etc.), mechanical quantities (force, length, width, thickness, displacement, vibration, etc.), and composition-related quantities (oxygen analyzers, calorimeters, neutron moisture meters, carbon-sulfur analyzers, etc.)... There are many more sub-classifications available. In addition to understanding these principles and maintenance, there is also knowledge in various areas such as instrument calibration, design, construction and installation, programming, and debugging....
First, measurement knowledge, then measuring instruments, control instruments, DSC....................
Principles of Automatic Control, Distributed Control Systems, Industrial Process Control Engineering, Automatic Detection Techniques and Instrument Control Systems, Principles and Applications of Sensors； Professional foreign languages! When I have nothing else to do, I go online and browse around, looking for some information of my own!
If you really want to understand it, take the time to read the instrument technician’s manual carefully, and also get more exposure to actual instruments on site – first learn to identify them, and then study their structural principles in depth.
