How to improve the anti-interference performance of pressure sensors?

In industrial applications, we often see a variety of pressure sensors, which are widely used in various industrial automation environments due to their small size, good temperature characteristics, and high accuracy. The use of pressure sensors in measurement is often subject to external interference, resulting in errors. This requires improving anti-interference measures for pressure sensors. Especially piezoelectric pressure sensors and capacitive pressure sensors are prone to interference. Generally speaking, anti-interference measures for pressure sensors are generally taken from a structural perspective. Intelligent pressure sensors can also be addressed through software.

Further improvement in anti-interference performance of pressure sensors

Improving the structure of pressure sensors can to some extent avoid the introduction of interference, and there are the following ways:

Integrate the signal processing circuit with the sensitive components of the sensor as a whole, that is, integration. In this way, the signal to be transmitted is enhanced and the anti-interference ability is improved. At the same time, because it is integrated, it reduces the introduction of interference. Integrated sensors have the characteristics of compact structure and strong functionality, which is conducive to improving anti-interference ability; Intelligent sensors can take anti-interference measures in software from multiple aspects, such as digital filtering, timing self calibration, characteristic compensation, and so on.

Once the anti-interference performance of a pressure sensor is poor, it is easy to be affected by external interference, and its value is discounted, and its application range is greatly limited. Pressure sensors are one of the most widely used sensors in industry, agriculture, and service industries. stay

It has applications in various environments, so anti-interference performance must be quite reliable.

At present, pressure sensors can adapt to many different types of environments, but in some environments, the anti-interference performance of pressure sensors is still not good enough. So, we must further improve the anti-interference performance of pressure sensors from multiple perspectives and combine high-tech.
