How to realize accurate measurement of force value control instrument?

To achieve accurate measurement by force control instruments, it is usually necessary to comprehensively use various technologies and methods. The following are some key measures:

Sensor selection and application

High-precision sensor: it is the basis to choose a force sensor with high precision and good stability. For example, strain sensor has high measurement accuracy and good linearity, and can convert force into electrical signal, thus providing guarantee for accurate measurement. Reasonable selection: select the appropriate sensor type and range according to the requirements of star measurement and environmental conditions, for example, the sensor with high temperature should be selected in high temperature environment and heat insulation measures should be taken; In humid or corrosive gas environment, sensors with good protective performance should be selected. Calibration and debugging

Strict calibration: calibrate the sensor before use to ensure that its output signal accurately corresponds to the actual force. Standard weights can be used for loading test, and parameters such as zero and sensitivity can be adjusted.

Periodic calibration: the instrument shall be calibrated regularly for long-term use or when the environment changes greatly, so as to maintain the measurement accuracy.

Signal processing and conversion

High-precision analog-to-digital converter (ADC): A high-resolution ADC is used to convert the analog signal output by the sensor into a digital signal, so as to improve the resolution and accuracy of measurement.

Signal conditioning circuit; A reasonable signal conditioning circuit is designed to filter and amplify the signal output by the sensor, so as to remove noise and interference and improve the signal quality. Environmental adaptability compensation Temperature compensation: Considering the influence of environmental temperature on the sensor and measuring circuit, temperature compensation technology is adopted, such as installing a temperature sensor near the sensor, monitoring the temperature change in real time and performing compensation calculation to reduce the influence of temperature on the measurement results. Compensation for other environmental factors: For environmental factors that may affect the measurement, corresponding compensation measures are also taken, such as adding protective devices and adopting shock absorption measures. Software algorithm optimization

Data processing algorithm: advanced data processing algorithms, such as Kalman filter and filtered network, are used to analyze and process the measured data, so as to further eliminate exposure and errors and improve the reliability and stability of the measured results. Intelligent control algorithm: according to the measurement demand and actual situation, develop intelligent control algorithm to monitor and adjust the force value control instrument in real time, so that it can automatically adapt to different working conditions and measurement requirements and realize more accurate measurement.
