Earth pressure measurement is an important method for soil mechanics research and civil engineering research. HCYB-16 soil stress sensor uses stainless steel structure, micro mechanical strain gauges as the core components, the use of international advanced miniaturization of production and packaging technology, exquisite and delicate. The package is small in size, compact in structure, light in weight, durable, and has excellent dynamic and static characteristics. This series of products is particularly suitable for civil simulation, centrifuge simulation, etc., widely used in rock and soil mechanics, soil mechanics, civil engineering engineering. And blasting tests.
