Sensors commonly used terms 30
Visit: Date:2013-11-29
To be provided to the feelings of measurement and according to certain rules to convert the output signal of the device or devices available. There are usually sensitive components and conversion components.

The sensitive element refers to the sensor can directly (or response) measured part.
The conversion element refers to a sensitive element feel sensor (or response) of conversion and transmission and (or) is part of the electrical signal measurement.
When the output is the standard signal set, called the transmitter.
2 measuring range
The allowed range of the measured value error limit.
3 range

The upper limit value of measuring range and the lower limit of differential algebra.
4 accuracy
The results of measurement are measured and the true value of the degree of agreement among.
5 from the renaturation

In all the following conditions, the degree of correspondence between the same quantity to be measured many times measuring results:
...... The same measurement method:
...... The same observer:
...... The same measuring instrument:
...... The same place:

...... The same conditions of use:
...... In the short period repeats.
6 resolution
Sensors in the specified measuring range circle minimal change the quantity being measured may be detected.
The 7 threshold

Can generate the minimum change of the quantity being measured measurable changes in the amount of the sensor output.
8 zero
The output of wood disaster drop plutonium 'Nao thorn heavier components Jin Yu thorn glue great ship? Lt; BR>9. excitation
The sensor is applied for the normal work of the external energy (voltage or current).

10 the maximum excitation

In the local conditions, can be applied to the maximum voltage or current sensors.
11 input impedance

In the output short circuit, impedance sensor input is measured.
The 12 output

A sensor generated and applied is measured as a function of power.
The 13 output impedance

At the end of the input circuit, the output end of the sensor measured impedance.
14 zero output

In the city conditions, the output is zero by measuring sensor.
15 lag

Within the scope of the provisions, when the measured value increase and decrease, the maximum difference in output.
16 later
The change of the output signal with respect to changes in the input signal time delay.
17 drift

In a certain time interval, the change does not need the sensor output was independent from the measurement.
18 zero drift

Changes in the time interval and the conditions prescribed under the indoor zero output.

The sensitivity of 19
Incremental sensor output and the corresponding input increment ratio.
20 sensitivity drift
Changes in the slope of the calibration curve caused by sensitivity to the variation of the.
21 thermal sensitivity drift
Sensitivity drift caused by the change of sensitivity.
22 thermal zero drift

Zero drift caused by the variation of ambient temperature.

23 linearity

The calibration curve with a specified for consistency.
The 24 Philippine linearity
The calibration curve with a specified linear degree of deviation.
25 long term stability
The sensor can still keep ability does not exceed the allowable error within the prescribed period of time.
26 by the rate of natural
In the absence of resistance, sensor free (without external force) by the rate of oscillation.
27 response

The characteristics of the output is measured changes.
28 compensation temperature range

The sensor to keep the temperature range and provisions of the compensation within the limit of the zero equilibrium.
29 creep

When the measured machine has many environmental conditions remain constant, changes in output within specified time.
30 insulation resistance
If no other provisions, the DC voltage regulation at room temperature, the insulation resistance between the measured values from the sensor
