About the linear range and stability of the sensor

1. Linear range

The linear range of the sensor refers to the scope of the output to the input. Theoretically, the sensitivity is kept at a fixed value within this range. The wider the linear range of the sensor, the larger the range of its range, and it can ensure a certain measurement accuracy. When choosing a sensor, when the type of sensor is determined, it is necessary to see if the range of the range meets the requirements.

But in fact, no sensor can guarantee linearity, and its linearity is relative. When the required measurement accuracy is relatively low, within a certain range, the sensor with less non -linear errors can be similar to linear, which will bring great convenience to the measurement.

2. Stability

After the sensor is used for a period of time, its performance remains unchanged as stability. Factors affecting the long -term stability of the sensor are the main environment of the sensor except the structure of the sensor itself. Therefore, to make the sensor have good stability, the sensor must have a strong environmental adaptability.

Before selecting the sensor, investigate in response to its use environment, select the appropriate sensor based on the specific use environment, or take appropriate measures to reduce the impact of the environment.

The stability of the sensor has quantitative indicators. After the use period, the calibration should be carried out before use to determine whether the performance of the sensor changes.

In the occasion that the sensor can be used for a long time without changing or calibration, the selected sensor stability requirements are more stringent, and the long test must be able to withstand the test.
