Displacement Sensors

A variety of displacement sensors are available at the GCC, ranging from laser sensors to LVDTs. They are typically used to measure vertical and horizontal displacements at characteristic model locations (e.g., foundation, structure) and on the surface of the soil model. For example, the Micro-Epsilon optoNCDT ILD1400-200 laser sensor is based on the triangulation principle. A visible light point is projected on the target surface using a laser source. The diffuse component of the reflected light is received by the optical receiver at a certain angle with respect to the axis of the laser beam, depending on the distance. The distance to the measurement object is calculated based on the position of the light on the receiver and the distance between the source and the receiver.
