General terminology for sensors

General terminology for sensors:

1. Measurement range, the range of measured values within the allowable error limit.

2, the range, the algebraic difference of 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, repeated within a short period of time.

5. Resolving power, the minimum amount of measured change that the sensor may detect within the specified measurement range.

6, the threshold value, can make the output end of the sensor produce measurable changes in the measured minimum change.

7. Input impedance The impedance measured at the input of the sensor when the output is short-circuited.

8, output, there is a sensor and the measured amount of power is added.

9, the output impedance, measured at the output of the sensor when the input is shorted.

10. Zero point output. Under indoor conditions, the output of the sensor when measured is zero.

11. Sensitivity, the ratio of the sensor output increment to the corresponding input increment.

12, linearity, the degree of alignment of the calibration curve with a given straight line.

13, non-linearity, the deviation of the calibration curve from a given straight line.

14, natural frequency, in the absence of resistance, the sensor's free (without external force) oscillation frequency.

15. Insulation resistance, if not otherwise specified, means the resistance value measured between the insulation parts of the sensor when a specified DC voltage is applied at room temperature.
