In the context of instrumentation, measurement systems refer to the set of instruments, devices, and methods used to quantify physical quantities and measure them accurately. Measurement systems in instrumentation typically involve the following components:
Sensor or transducer: A device that converts the physical quantity being measured into an electrical signal that can be measured and processed by other instruments.
Signal conditioning circuitry: A set of circuits and components that amplify, filter, and process the electrical signal from the sensor or transducer to make it suitable for measurement.
Data acquisition system: A system that samples, digitizes, and stores the processed electrical signal from the signal conditioning circuitry.
Display and recording devices: Devices such as meters, oscilloscopes, and recorders that display or record the measured physical quantity.
Calibration and reference standards: A set of standards and procedures used to ensure the accuracy and reliability of the measurement system.
Measurement systems in instrumentation can be designed to measure a wide range of physical quantities, including temperature, pressure, flow, level, position, displacement, vibration, and many others. The selection of the appropriate measurement system depends on the specific application and the required level of accuracy and precision.
