Methods to make pressure sensor have longer service life

1. Regular maintenance

   
   

Regular maintenance of pressure sensor is one of the important methods to prolong its life. Regularly check whether the electrical connection of the sensor is good, check whether the connecting wire is damaged or loose, and ensure the stable signal transmission. At the same time, clean the dust and dirt on the sensor surface and keep it clean. In addition, check the fastening of the sensor, and fasten it in time if it is loose, so as to ensure that the performance of the sensor will not be affected by vibration or displacement during work. Through these regular maintenance work, the sensor can always be kept in good condition.

Step 2 Install it correctly

It is very important to install the pressure sensor correctly to avoid its damage. Before installation, the appropriate installation position should be selected according to the measuring medium, temperature and humidity, explosion-proof requirements and other factors to ensure the normal operation and easy maintenance of the sensor. During the installation process, we should strictly follow the installation steps, clean the pressure interface, install the sealing gasket, gently place the sensor on the sealing gasket and align the interface, and then fix it on the installation frame with screws. When connecting pipelines, ensure that the joints are tight and leak-free, and test and calibrate after installation to ensure the accuracy and reliability of sensors.

3. Rational use

When using the pressure sensor, it is necessary to strictly observe its measuring range and frequency requirements, and use it within the specified range to ensure the safe operation of the sensor. Avoid using the sensor under too high pressure or collar rate to prevent it from being damaged. At the same time, the appropriate type of sensor should be selected according to the actual demand. For example, for applications that require high response speed, the negative pressure sensor with good response and response characteristics can be selected, but the influence of size on signal noise and measurement accuracy should be paid attention to.

4. Regular calibration

The key to ensure its accuracy is to calibrate the pressure sensor regularly. Generally speaking, it is recommended to calibrate the sensor once every six months or once a year. In calibration, the sensor can be calibrated by using a standard pressure source, and its output value can be adjusted to be different from the standard value. If the output value of the sensor is found to be different from the actual value, it should be calibrated in time. For some applications that require high accuracy, more frequent calibration may be needed.

5. moistureproof and dustproof

When the pressure sensor is used in harsh environment, special attention should be paid to moistureproof and dustproof. Moistureproof materials, sealing design and special surface treatment can be used to improve the anti-gradual performance of the sensor. For dustproof, a protective cover can be installed or other protective measures can be taken to prevent dust from entering the sensor and affecting its performance. At the same time, it is necessary to regularly check whether the moisture-proof and dust-proof measures of the sensor are effective, and handle them in time if there are any problems.

6. Storage management

Pressure sensors that are not used for a long time should be stored in a dry and ventilated place to avoid direct sunlight and strong vibration. Before storage, they should be cleaned and calibrated to ensure their good performance. Check the performance parameters and appearance of the sensor regularly, and handle the problems in time when they are found. During storage, pay attention to prevent the sensor from being corroded and damaged.

7. Technology update

Pay attention to the technical development of pressure sensor industry, and adopt new technologies to upgrade sensors in time. For example, adopting new materials can improve the performance of sensors, and adopting new technologies can reduce production costs and improve production efficiency. At the same time, we should choose suitable new technologies according to actual needs to ensure that sensors can meet changing application requirements.

8. Professional operation

The installation, debugging and maintenance of pressure sensors should be carried out by professionals, who have rich experience and professional knowledge, can correctly install and debug sensors, find and solve problems in time, and avoid improper operation.
