Sensors are commonly used terms

1 sensor can feel the provisions is measured and converted into usable output signal according to certain rules of device or devices. There are usually sensitive components and conversion components.

(1) sensitive element refers to a sensor that can be directly ( Or response) Be part of the measurement.

2) conversion element refers to the sensor can feel sensitive element ( Or response) Quantity is converted to and transfer and (on the north side of the Or) Measuring the electrical signals.

(3) when the output is the standards set by the signal, it is called a transducer.

2

range within the allowed error limits the range of measured values.

3 range measurement range difference upper limit and lower limit of algebra.

4 accuracy by measuring the degree of agreement between the measured results and the true value. In a short period of repetition.

6 discrimination 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 output is the absolute value of the smallest states, such as balance. Incentive

9 for the sensors work and exert external energy ( Voltage or current) 。

10 biggest incentive

under the condition of the city, can be applied to a maximum of the excitation voltage or current on the sensor.

11 input impedance on the output side short circuit, sensor input end of the measured impedance.

12 output of produce and relations of power as a function of plus is measured.

13 output impedance in the input circuit, sensor output measured impedance. 14 zero output

under the condition of the city, and is measured by the output of the sensor is zero. 15 lag

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

output signal changes after 16 late relative to the time delay of the input signal.

17 drift in certain time interval, the sensor output was measured irrelevant don't need to change. 18 zero drift

in the specified time interval and interior changes under the condition of zero output.

19 sensitivity sensor output increment and the ratio of the corresponding input increment.

20 sensitivity drift due to the change of sensitivity caused by changes in the slope of the calibration curve.

21 thermal sensitivity drift caused by sensitivity to changes in the sensitivity drift.

22 thermal zero drift caused by temperature variation around the zero drift.

23 degree of linearity of calibration curve and limited to a certain rules. 24 Philippine linearity

calibration curve with a linear deviation degree.

long-term stability 25 sensors within the prescribed period of time still retain the ability to not exceed the permitted error.

26 inherent with rate, in the absence of resistance sensor free ( Without external force) Oscillation by rate.

27 response by measuring the output of the characteristics of the change.

28 compensation temperature range makes the sensor keep within limits prescribed range and compensation temperature scope of zero balance. 29 creep

when many measuring machine when environmental conditions remain constant, the change of output within the given time. 30 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.
