How do calibration and testing machines work? What core technologies and sensors are used?

The working principle of calibration and testing machines and the core technologies and sensors used depend on their measurement objects and measurement parameters. The following is the working principle and commonly used core technologies and sensors of calibration and testing machines in general:

working principle:

The working principle of calibration and testing machines is basically to use sensors to convert physical quantities to be measured into electrical signals, and then through data processing and analysis, the final measurement results are obtained. The sensor measures changes in physical quantities, converts them into electrical signals, and then undergoes amplification, filtering, digitization and other processing to finally obtain accurate measurement values.

Core Technology:

Sensor technology: Sensors are the core component of calibration and testing machines, used to detect changes in physical quantities to be measured and convert them into electrical signals.

Data processing technology: including digitization of analog signals, signal processing algorithms, data analysis and result display, etc., used to process and analyze the collected data to obtain the final measurement results.

Automatic control technology: used to control the operation of calibration and testing machines to realize functions such as automatic calibration and automatic testing.

Commonly used sensors:

Pressure sensor: used to measure pressure parameters. Common sensors include pressure resistor, pressure capacitor, pressure strain and other sensors.

Temperature sensor: used to measure temperature parameters. Common ones include thermocouples, thermal resistors, infrared temperature sensors, etc.

Displacement sensor: used to measure the displacement or displacement change of an object. Common ones include photoelectric encoders, capacitive displacement sensors, laser displacement sensors, etc.

Flow sensor: used to measure the flow parameters of fluids. Common ones include turbine flowmeters, electromagnetic flowmeters, ultrasonic flowmeters, etc.
