Soil pressure sensors are now widely used in fields such as underground tunnel engineering. They are resistant to high pressure and high temperature and can maintain long-term stability. When purchasing and using them, it is necessary to test the equipment. So, what are the testing methods for soil pressure sensors? Let's take a closer look below.
Soil pressure sensors use a specially treated, robust diaphragm. Its structure is compact, allowing for temperature compensation over a wide range. It also offers advantages in terms of shock resistance, impact resistance, and corrosion resistance. The material is stainless steel, and it also features an anti-clogging structural design. The sensor can be installed directly, with the measuring element in direct contact with the medium being measured. The testing method for this equipment is as follows:
Testing a soil pressure sensor requires a specialized testing chamber. This chamber uses a housing to confine an airbag on top of the soil pressure sensor. This airbag inflates, applying pressure to the soil pressure sensor. The soil pressure sensor detects the pressure from the inflated airbag, and a pressure sensor also detects the pressure from the airbag. This provides two measurements, allowing for an accurate determination of whether the soil pressure sensor is functioning correctly.
Before putting the equipment into use, it's necessary to check if the installed soil pressure sensor has malfunctioned. This effectively reduces the failure rate and allows for post-installation testing of the soil pressure sensor, which is also very convenient to operate. This can be considered a significant technological advancement.
The above introduces the testing of soil pressure sensors. When testing, choose appropriate testing tools and methods. During use, strictly follow the operating procedures. For those who need Ailita instrumentation, please contact the website staff.
