Sensors in the development of the growing today, our understanding of it is more and more deep, 30 the commonly used term is summarized as the following:

1. Range: measuring range difference upper limit and lower limit of algebra.

2. Accuracy: by measuring the degree of agreement between the measured results and the true value.

3. There are usually sensitive components and conversion components.

(1) sensitive element refers to a sensor that can be directly (or response) is measured.

(2) conversion element refers to the sensor can feel (or response) on the north side of the sensitive element quantity is converted to and transmission and electrical part of (or) measurement.

(3) when the output is prescribed standard signal, it is called a transducer.

4. The measuring range: within the allowed error limits the range of measured values.

5. Repetitive: in all the following conditions, many times to the same measured the amount of continuous measurement results conform to the degree between:

The same measurement:

The same observer:

The same measuring instrument:

The same place:

The same conditions of use:

In a short period of repetition.

6. Resolution: the sensor in the specified measuring range circle could detect the smallest change of the measured quantity.

7. Threshold: can make the sensor output produces measurable changes in the smallest change of the measured quantity.

8. Zero: the absolute value of the output is the smallest state, such as balance.

9. Linearity: the calibration curve and limited to a certain rules.

10. Philippines linearity: the calibration curve and a linear deviation degree.

11. Long term stability: sensors within the prescribed period of time still retain the ability to not exceed the permitted error.

12. With natural rate: in the absence of resistance sensor free oscillation by rate (without external force).

13. Response: by measuring the output of the characteristics of the change.

14. Compensation temperature range: keep the sensor range and zero balance compensation within the limit specified temperature range.

15. Creep: when measured many machines when environmental conditions remain constant, the change of output within the given time.

16. Insulation resistance: if no other regulations, refers to the dc voltage of applying rules at room temperature, the rules from the sensor measured resistance value between insulation parts.

17. Motivation: in order to make the normal work of the sensor and applying external energy (voltage or current).

18. The biggest motivation: under the condition of the city, can be applied to a maximum of the excitation voltage or current on the sensor.

19. Input impedance: short circuit on the output end, the end of the sensor input is measured impedance.

20. Output: produce and plus be measured into a power function relationship.

21. Output impedance: short circuit at the input end, the impedance of the sensor output measured.

22. Zero output: under the condition of the city, and is measured by the output of the sensor is zero.

23. Lag: within the prescribed scope, when measured value increases and decreases, the output in one of the biggest difference.

24. Later, the output signal changes relative to the input signal time delay.

25. Drift: in certain time interval, the sensor output was measured irrelevant don't need to change.

26. Zero drift: under the condition of specified time interval and indoor zero output changes.

27. The sensitivity: sensor output increment and the ratio of the corresponding input increment.

28. Sensitivity drift: due to the change of sensitivity caused by changes in the slope of the calibration curve.

29. Thermal sensitivity drift: sensitivity drift caused due to the change of sensitivity.

30. Thermal zero drift, zero drift caused by temperature change around.
