The Sensor terminology

 
 1. Measurement range
 
The range of measured values ​​within the allowable margin of error.
 
2. Range
 
The algebraic difference between the upper and lower limits of the measurement range.
 
3. Accuracy
 
The degree of agreement between the measured result and the true value.
 
4. Repeatability
 
The degree of coincidence between the results of multiple consecutive measurements of the same measured quantity under all of the following conditions: the same measurement method, the same observer, the same measuring instrument, the same location, the same use conditions, and within a short period of time repeat.
 
5. Resolution
 
The smallest possible amount of change that the sensor may detect in the specified measurement range circle.
 
6. Threshold
 
The smallest change that can be measured at the output of the sensor to produce a measurable change.
 
7. Zero position
 
Make the absolute value of the output minimum, such as the equilibrium state.
 
8. Incentive
 
The external energy (voltage or current) applied to make the sensor work properly.
 
9. Maximum incentive
 
The maximum value of the excitation voltage or current that can be applied to the sensor.
 
10. Input impedance
 
When the output is short-circuited, the measured impedance of the sensor input.
 
11. Output
 
There is an amount of electricity generated by the sensor that is measured as a function of the sum.
 
12. Output impedance
 
The measured impedance at the output of the sensor when the input is short-circuited.
 
13. Zero output
 
The output of the sensor is added when it is measured to zero.
 
14. Lag
 
Within the specified range, the maximum difference that occurs in the output when the measured value increases and decreases.
 
15. Late
 
The time delay of the change in the output signal relative to the input signal.
 
16. Drift
 
At certain intervals of time, the amount of unwanted change in the sensor output that is independent of the measured value.
 
17. Zero drift
 
Change at zero output during specified time intervals and room conditions.
 
18. Sensitivity
 
The ratio of the sensor output increment to the corresponding input increment.
 
19. Sensitivity drift
 
Changes in the slope of the calibration curve due to changes in sensitivity.
 
20. Thermal sensitivity drift
 
Sensitivity drift due to changes in sensitivity.
 
21. Hot zero drift
 
Zero drift due to changes in ambient temperature.
 
22. Linearity
 
The extent to which the calibration curve is consistent with a provision.
 
23. Non-linearity
 
The degree to which the calibration curve deviates from a given straight line.
 
24. Long-term stability
 
The sensor can still maintain its ability to exceed the allowable error for a specified period of time.
 
25. Natural frequency
 
When there is no resistance, the sensor is free (without external force) oscillation frequency.
 
26. Response
 
The characteristics of the measured change at the time of output.
 
27. Compensation temperature range
 
Keep the sensor within the temperature range compensated by the zero balance within the range and the specified limits.
 
28. Creep
 
When the machine to be measured has a constant environmental condition, when specified
