The performance of pressure sensor is influenced by many factors.

The performance of pressure sensor is influenced by many factors, and the following are some main factors:

Temperature: Temperature is an important factor affecting the performance of pressure sensors. Because pressure sensors are usually manufactured based on some physical effects (such as positive pressure effect, piezoelectric effect, etc.), these physical effects will change with the change of temperature, which will lead to the increase of measurement error. For example, the sensitive element of the sensor may be deformed or aged in high temperature environment, which will further affect its measurement accuracy and stability.

Power supply: For some types of pressure sensors (such as piezoelectric sensors), the stability of external power supply is very important to their performance. Failure of power supply or reverse polarity of power supply may lead to sensor failure. Mechanical load: Excessive mechanical load may exceed the tolerance range of the sensor, resulting in the sensor not working normally or being damaged. Sealing: The better the sealing of the sensor, the less easily it is affected by the external environment, and the better it can keep the pressure of the internal liquid stable. However, the cost of a completely sealed sensor may be higher than environmental factors: besides temperature, environmental factors such as temperature, vibration and electromagnetic interference may also affect the performance of the pressure sensor. Some advanced pressure sensors have the functions of temperature and mixing compensation, which can maintain stable accuracy under different environmental conditions. Processing technology: The production and processing technology of pressure sensor will also affect its accuracy. High quality manufacturing technology and material selection can provide a more stable and reliable pressure sensor. Calibration and periodic inspection: Pressure sensors need to be calibrated before use, and should be inspected regularly to ensure accuracy. The calibration process needs to use standard equipment and methods to ensure the accuracy of measurement results. Design factor: The design of pressure sensor is also one of the key factors affecting its performance. Different design ideas and methods can achieve different performance indexes, for example, 0. Classical design ideas use traditional elastic yellow structure, while new design ideas such as fiber grating sensors and electro-positive sensors can achieve higher performance indexes. In addition, factors such as linearity, temperature drift and amplitude change need to be considered in the design. To sum up, there are many factors that affect the performance of pressure sensor. In practical application, it is necessary to choose the appropriate pressure sensor according to the use environment and demand of the county, and install and use it correctly to ensure its normal work.
