Ground pressure sensor with experimental protection device

Ground pressure sensor with experimental protection device, including column type loading sensor, the bottom of column type loading sensor is equipped with the bottom plate, the upper portion of column type loading sensor is equipped with the sensor hood, the top of sensor hood is equipped with the roof, the top subsides of roof are equipped with the welt, it is equipped with a plurality of guide bars to encircle column type loading sensor between roof and bottom plate, the lower part of every guide bar links to each other with the bottom plate is fixed respectively, the top of every guide bar do not adopts clearance fit to pass the face of roof, it is equipped with compression spring to overlap respectively on every guide bar, push up respectively on the lower surface of roof on every compression spring's top, column type loading sensor, the outside cover of bottom plate and roof is equipped with the protection box. It is experimental that its aim at provides a ground pressure who can be used to endless track vehicle to effective transmitting data, support endless track vehicle's that can be effective, steady weight prevents that soil from getting into the sensor and inside and lead to the ground pressure sensor with experimental protection device of its damage.
