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.

根据菲尼克斯传感器的稳定性传感器使用一段时间后，其性能保持不变的能力称为稳定性。影响传感器长期稳定性的因素除传感器本身结构外，主要是传感器的使用环境。因此，要使传感器具有良好的稳定性，传感器必须要有较强的环境适应能力。

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.

在选择传感器之前，应对其使用环境进行调查，并根据具体的使用环境选择合适的传感器，或采取适当的措施，减小环境的影响。传感器的精度越高，其越昂贵，因此，传感器的精度只要满足整个测量系统的精度要求就可以，不必选得过高。

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.
