How to improve the anti-interference performance of Honeywell pressure sensor
Release date: July 6, 2019
In the industrial application, we can often see a variety of pressure sensors. They are widely used in various industrial automatic control environments because of their small size, good temperature characteristics and high accuracy. The use of pressure sensors in the measurement is often subject to external interference, resulting in errors. It is necessary to improve the anti-interference measures of pressure sensor. Especially piezoelectric pressure sensor and capacitive pressure sensor are easy to be interfered. Generally speaking, the anti-interference measures of pressure sensor generally start from the structure. The intelligent pressure sensor can also be solved from the software.
To some extent, the introduction of interference can be avoided by improving the structure of pressure sensor
The signal processing circuit and the sensitive element of the sensor are integrated. In this way, the ability of anti-interference is enhanced. At the same time, because it is integrated, the introduction of interference is reduced; the integrated sensor has the characteristics of compact structure and strong function, which is conducive to improving the anti-interference ability; the intelligent sensor can take anti-interference measures in software from many aspects, such as digital filtering, timing self-tuning, characteristic compensation and so on.
Once the anti-interference performance of pressure sensor is poor, it is easy to be interfered by the outside world, so its value is discounted, and its application range is greatly limited. Pressure sensor is one of the most widely used sensors, which is widely used in industry, agriculture and service industry. It can be used in various environments, so the anti-interference performance must be quite reliable. At present, the pressure sensor has been able to adapt to many different types of environment, but in some environments, the anti-interference performance of the pressure sensor is still not good enough. Therefore, we must improve the anti-interference performance of the pressure sensor from multiple angles and combined with high-tech.
