1、 Measurement range

　　The measurement range of a pressure sensor is one of the primary considerations for selection. According to practical application requirements, it is necessary to determine the pressure range to be measured and select sensors that can meet this range. A small measurement range may result in inaccurate measurement of high or low voltage, while a large measurement range may lead to insufficient sensitivity or increased measurement errors.

　　2、 Accuracy and Resolution

　　Accuracy refers to the degree of deviation between the output value of a pressure sensor and the true value, while resolution refers to the minimum pressure change that the pressure sensor can detect. When selecting a pressure sensor, it is necessary to consider the requirements for accuracy and resolution in practical applications. In general, the higher the accuracy and resolution, the more accurate the measurement results of the pressure sensor.

　　3、 Response time

　　Response time refers to the time taken by a pressure sensor from receiving a pressure signal to outputting detection results. In certain application scenarios, such as rapidly changing pressure conditions, shorter response times are particularly important. Therefore, when selecting a pressure sensor, it is necessary to understand its response time and ensure that it can meet practical application requirements.

　　4、 Temperature characteristics

　　Temperature has a significant impact on the performance and accuracy of pressure sensors. Different pressure sensors may exhibit different characteristics under different temperature conditions. When selecting a pressure sensor, it is necessary to consider its temperature characteristics, that is, to understand its measurement accuracy and stability in different temperature ranges. Especially for applications under extreme temperature conditions, it is necessary to choose sensors that can adapt to high or low temperature environments.
