The linear range of Phoenix sensor refers to the range in which the output is proportional to the input. Within this range, the sensitivity remains constant. The wider the linear range of the sensor is, the larger the measuring range is, and the measurement accuracy can be guaranteed. But in fact, any sensor can not guarantee the linearity of the Jue pair, and its linearity is also relative. When the required measurement accuracy is relatively low, in a certain range, the sensor with small nonlinear error can be approximately regarded as linear, which will bring great convenience to the measurement.

根據菲尼克斯傳感器的穩定性傳感器使用一段時間后，其性能保持不變的能力稱為穩定性。影響傳感器長期穩定性的因素除傳感器本身結構外，主要是傳感器的使用環境。因此，要使傳感器具有良好的穩定性，傳感器必須要有較強的環境適應能力。

According to the stability of the Phoenix sensor, the ability of the sensor to keep its performance unchanged after a period of use is called stability. Besides the structure of the sensor itself, the main factor affecting the long-term stability of the sensor is the use environment of the sensor. Therefore, in order to make the sensor have good stability, the sensor must have strong environmental adaptability.

在選擇傳感器之前，應對其使用環境進行調查，并根據具體的使用環境選擇合適的傳感器，或采取適當的措施，減小環境的影響。傳感器的精度越高，其價格越昂貴，因此，傳感器的精度只要滿足整個測量系統的精度要求就可以，不必選得過高。

Before the selection of sensors, the use environment should be investigated, and appropriate sensors should be selected according to the specific use environment, or appropriate measures should be taken to reduce the impact of the environment. The higher the accuracy of the sensor, the more expensive it is. Therefore, the accuracy of the sensor can only meet the accuracy requirements of the whole measurement system, and it does not have to be too high.
