Application scope
It can be applied to the health monitoring of expressways, slope monitoring, soil stress in building foundations such as earth-rock DAMS, breakwaters, revetments, and wharf walls, soil stress in building foundations such as high-rise buildings, bridge piers, retaining walls, tunnels, subways, and airports, compressive stress between building foundations and soil in structures such as highways, railways, and anti-seepage walls, and the measurement of freeze-thaw force in glaciers and permafrost.
Introduction to Sensors
It is not affected by electromagnetic interference, intrinsically explosion-proof, anti-electromagnetic interference, lightning-proof, with good temperature resistance, corrosion resistance and aging resistance. It can simultaneously obtain temperature and pressure information of the test point, with high precision and high resolution. It can achieve distributed measurement, integrated packaging, more stable performance, simple to use, quick to install and can be reused.
