1 range: the algebraic difference between the upper and lower limits of the measurement range.

2 accuracy: the measured results are consistent with the true values.

3 there are usually sensitive components and conversion components.

A sensing element is a part that can be measured directly (or response) in a sensor.

The conversion element refers to a sensor that is capable of feeling (or responsive) to the north side of the sensing element and is converted into a portion of the electrical signal that is transmitted and (or) measured.

When the output is the standard signal, it is called the transmitter.

4 measurement range: the range of the measured value within the allowable error limit.

5 repeatability: in all of the following conditions, the degree of conformity between the results obtained by repeated measurements of the measured amount of the same:

Same measuring method:

The same observer:

Same measuring instrument:

Same place:

Same conditions of use:

Repetition in a short period of time.

6 resolution: sensors in the measurement range of the measurement can be detected by measuring the smallest change.

7 threshold: the smallest amount of change that can be measured at the output of the sensor.

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

9: the linearity of the calibration curve and a limit of consistency.

The degree of deviation from the calibration curve and the linear deviation of a specified line in the 10 phenanthrene.

11 long term stability: the sensor can be kept within the specified time is not more than the ability to allow errors.

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

13 response: the characteristics of the measured changes in output.

14 the range of compensation temperature: the temperature range of the sensor to keep the range and the zero balance within the prescribed limit.

15 creep: when the machine is measured to be more than the environmental conditions remain constant, the amount of change in the specified time.

16 insulation resistance: if no other requirements, refer to the provisions of the DC voltage at room temperature, the provisions of the insulation between the measured value from the sensor.

17 excitation: the external energy (voltage or current) applied to the sensor to work properly.

18 maximum excitation: in the city conditions, the maximum value of the excitation voltage or current can be applied to the sensor.

19 input impedance: short circuit at the output, the input impedance of the sensor.

20 output: sensor generated and applied to be measured as a function of the relationship between the amount of electricity.

21 output impedance: in the input side of the short circuit, the output of the sensor measured impedance.

22 zero point output: the output of the sensor is measured at zero in the city.

23 lag: in the specified range, when the measured value increases and decreases, the maximum difference occurs in the output.

24 later: the time delay of the change of the output signal with respect to the change of the input signal.

25 drift: in a certain time interval, the output of the sensor has finally been measured independent of the amount of change is not required.

26 zero drift: the variation of the zero output at the specified time interval and indoor conditions.

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

28 sensitivity shift: the slope of the calibration curve due to the change in sensitivity.

29 thermal sensitivity drift: sensitivity drift due to changes in sensitivity.

30 thermal zero drift: zero drift due to temperature variation around.
