Instrumentation is used to detect, measure, observe, calculate various physical quantities, material composition, physical parameters and other appliances or equipment, in the industrial, scientific research, medical, environmental protection and many other fields play a key role. The following is a detailed introduction to instrumentation:
I. Classification of instrumentation
There are many types of instrumentation, which can be divided into various types according to different classification standards. Common classification methods include:
Classification by function:
Testing instrumentation: Used to detect various physical quantities, chemical quantities, etc., such as temperature measuring instruments, pressure measuring instruments, flow measuring instruments, etc.
Regulation instrumentation: Used to automatically adjust the production process, such as pneumatic regulating instruments, electric regulating instruments, etc.
Display instrument: Used to display measurement or control results, such as digital display instrument, analog display instrument, etc.
Actuator: Performs corresponding actions according to control signals, such as electric actuators, pneumatic actuators, etc.
Classified by application field:
Industrial automation instrument: Used for automatic control of industrial production process, such as pressure transmitter, flow meter, etc.
Medical instrument: Used for medical diagnosis and treatment, such as nuclear magnetic resonance, CT scan, etc.
Environmental protection instrument: Used for environmental monitoring and governance, such as water quality analyzer, gas detector, etc.
Scientific research instrument: Used for scientific research and experiments, such as spectrometer, mass spectrometer, etc.
Classified according to the principle of structure:
Mechanical instrument: Using mechanical principles for measurement and display, such as glass thermometer, pressure thermometer, etc.
Electronic instrument: Using electronic technology for measurement and display, such as digital multimeter, electronic balance, etc.
Intelligent instrument: Integrated microprocessor and computer technology, with automatic diagnosis, predictive maintenance and other functions, such as intelligent pressure transmitter, intelligent flow meter, etc.
