The calibration process of the tension sensor is an important link to ensure the accuracy of its measurement results. The calibration process usually requires accurate equipment, professional technology and strict procedures. The following is a brief analysis of the calibration process of the tension sensor, which is divided into the basic principles of calibration, calibration steps, data processing, inspection and maintenance after calibration, and other parts for detailed description.
1、 Calibration Rationale
The basic principle of tension sensor calibration is to calibrate the output of the sensor through the known standard force value to ensure that the corresponding relationship between the measured value and the actual force value is accurate. During calibration, apply the standard load to the sensor, read the output of the sensor, and then compare these outputs with the standard load. Adjust the output parameters of the sensor to make them consistent with the standard load.
2、 Calibration procedure
1. Preliminary inspection: Conduct appearance inspection on the tension sensor and connecting wire to eliminate physical damage or poor contact.
2. Installation setting: install the tension sensor on the test bench or calibration device, and ensure that it is aligned with the line of action of the force.
3. Zero calibration: carry out zero calibration without load to ensure that the output of the tension sensor is zero.
4. Loading: use a standard tension meter or a weight of known mass to load ASP- 134488-01 The sensor exerts a predetermined force, usually including multiple points of the rated range of the sensor (such as 10%, 20%, 50%, 80%, 100%, etc.).
5. Reading record: record the output value of the tension sensor at each load point.
3、 Data processing
1. Linearity check: analyze the relationship between the sensor output and the actual load, and check its linearity.
2. Sensitivity calculation: calculate the sensitivity of the sensor through the applied known force and the corresponding output value.
3. Error analysis: calculate the error between the actual value and the theoretical value, and judge whether it is within the allowable range.
4. Calibration curve: if necessary, draw a calibration curve according to the data to provide reference for subsequent use.
4、 Inspection and maintenance after calibration
1. Repeatability inspection: load and unload one or more load points several times to check the repeatability of sensor output.
2. Calibration cycle: determine the calibration cycle of the tension sensor according to the use frequency and environmental conditions.
3. Calibration certificate and record: issue calibration certificate, record calibration data and date, and provide reference for next calibration.
5、 Conclusion
The calibration process of tension sensor is a precise work, which requires high-precision calibration equipment, professional technicians and strict operating procedures. By accurately calibrating the tension sensor, the accuracy of its measurement results can be ensured, thus ensuring the safety and reliability of related fields. Regular calibration and maintenance is also the key to ensure the long-term stable work of the sensor.
