1: Product Overview
The SCYG315 series soil pressure sensor adopts a thin circular cake structure design, a reasonable circle to diameter ratio, and a flat membrane structure to ensure the accuracy of testing. It has the advantages of ultra-thin, waterproof, oil resistant, high stability, and good dynamic and static performance. Suitable for measuring the dynamic contact pressure of model structures and dynamic stress of roadbeds in indoor model testing work of civil engineering, centrifugal model testing, retaining wall model testing, and measuring the pressure changes of buried soil in soft soil, sandy soil, and fill soil. In the field of military testing, it is used for the impact of explosive shock waves on components such as buildings and defense structures.
