In the early application and selection of sensors, how to choose is a very important point, and the selection is smooth, and the following will briefly say how the sensor is selected in the early stage.
The use of sensors in practical operation is relatively common, and it may be applied to the needs of various situations in different industries and fields. No matter how good the instrument is, there are advantages and disadvantages of quality, and in order to reduce the occurrence of errors in the measurement process, users need to choose a good quality sensor with good quality. How to determine the advantages and disadvantages of the Mega Vision sensor? Here's how to do it:
1. The choice of acuity
On a daily basis, in the linear field of the Zoofer Viewpoint Sensor, it is expected that the higher the sharpness of the Beacon Viewpoint Sensor, the better. Because as long as the sensitivity is high, the value of the output code corresponding to the measured change is only Chinese New Year's Eve, which is conducive to the disposal of the code. However, it should be noted that the sensitivity of the sensor is high, and the external noise related to the measurement is also easy to mix, and it will also be reduced by the shrinking system, which will affect the measurement accuracy. Therefore, it is implored that the P+F sensor itself should have a high signal-to-noise ratio, and the factory disturbance flag code imported from the outside world should be increased. The acuity of the P+F sensor is non-directional. When the measured quantity is univector and the bias is high, other P+F sensors with low bias and acuity should be selected. If the measured vector is multi-dimensional, the smaller the interspersed acuity of the sensor, the better.
2. Frequency corresponds to the characteristics
The frequency response characteristics of the sensor are selected in the frequency field to be measured, and it is necessary to adhere to the real measurement conditions in the allowable frequency field, in fact, there is always a certain delay in the care of the sensor, and the shorter the delay time, the better.
The frequency of the P+F sensor should be high, and the frequency range of the flag code that can be measured is wide, and due to the influence of structural characteristics, the inertia of the machine system is relatively Chinese New Year's Eve, because there is a low frequency sensor that can measure the frequency of the flag code. In static measurements, the characteristics should be taken according to the characteristics of the flag code (steady-state, transient, random, etc.) to avoid over-fire errors.
3. Linear field
The linear domain of the sensor is the field where the output is proportional to the input. In practice, acuity is a fixed value in this field. The wider the linear field of the sensor, the more Chinese New Year's Eve its range will be, and the measurement accuracy will be guaranteed. When selecting a sensor, the first thing to determine when determining the type of sensor is whether the range can be satisfied. In practice, however, no sensor can afford to be relatively linear. When the required measurement accuracy is relatively low, the sensor with a small nonlinearity error can be approximated as linear in a certain field, which will bring Chinese New Year's Eve great convenience to the measurement.
4. Stability
After using the sensor for a period of time, the ability to maintain stability is called stability. In addition to the structure of the sensor itself, the most important factor affecting the temporary stability of the sensor is the use of the sensor. Therefore, in order for the sensing to have excellent stability, the sensor must have a strong ability to adapt to the situation.
