A pressure sensor is a sensor that converts pressure into an electrical signal for output. Pressure sensors are widely used, such as industrial automation environment, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries. When we often use pressure sensors, data errors are inevitable. So when there is an error, which directions should we deal with it? We can analyze the rated pressure range, maximum pressure range, damage, linearity, pressure hysteresis temperature range and so on!

1.If the pressure sensor has poor anti-interference, it is particularly vulnerable to external interference, so its application scope will be greatly limited. Pressure sensor is one of the most widely used sensors, which is widely used in industry, agriculture and service industry.

2.The pressure sensor directly contacts or approaches the measured object to obtain information. Both the pressure sensor and the measured object are in the disturbed environment at the same time, which is inevitably interfered by the outside world.

3.In particular, piezoelectric pressure sensors and capacitive pressure sensors are easily disturbed. The anti-interference measures of pressure sensor generally start from the structure. Intelligent pressure sensor can also be solved by software.

4.Improving the structure of pressure sensor can avoid the introduction of interference to some extent, and there are the following ways: making the signal processing circuit and the sensitive element of the sensor into 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; The integrated sensor has the characteristics of compact structure and strong function, which is beneficial to improve the anti-interference ability; Intelligent sensors can take anti-interference measures in software from many aspects, such as digital filtering, timing self-calibration, characteristic compensation and so on.

At present, the pressure sensor can be used in many environments, but in some environments, the anti-interference of the pressure sensor is still not good enough. We must further improve the anti-interference of the pressure sensor from various angles and combined with high technology.
