What should be paid attention to when using soil pressure sensors?

A soil pressure sensor is a type of sensor that measures the contact stress between the surface of structures (such as embankments, retaining walls, dams, and roads) and the soil medium, as well as the original stress state of the soil layer. This information is used to evaluate the working condition of the construction site and verify soil stress distribution theories. So, what precautions should be taken when using a soil pressure sensor? Let's have a detailed introduction from the editor of Ailita Instruments and Meters.
First, when using a soil pressure sensor, handle it with care. Avoid any vibration, especially during measurement, as this can cause significant output errors. Therefore, it's crucial to be thoroughly familiar with the sensor's usage and precautions to avoid affecting the final measurement accuracy.
Second, to prevent large currents from directly passing through the soil pressure sensor and damaging it, avoid welding near the sensor after installation. If absolutely necessary, connect a bypasser made of copper braided wire to both ends of the sensor's loading device. Trained personnel would not make such a basic mistake. Therefore, selecting qualified personnel is crucial to ensure the proper use of the sensor; untrained individuals should not operate it.
Third, keep the soil pressure sensor's cable away from high-power power lines or areas with pulsed waves. If unavoidable, run the cable through a metal pipe and shorten the connection distance as much as possible. After use, store the sensor in a dry, ventilated environment free of corrosive gases.
In summary, using a soil pressure sensor is relatively simple. Just remember the above points and avoid making these mistakes during operation. Of course, there are many types of soil pressure sensors; choose a suitable brand based on your specific needs.
