[0002] Artificial sand refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements. Artificial sand and gravel are important building materials for buildings, roads, bridges and other infrastructure. In the process of concrete configuration, in addition to the gradation, particle shape and stone powder content of artificial sand affecting the quality of concrete, the moisture content of artificial sand also has a great influence on the quality of concrete. Therefore, it is usually necessary to measure the moisture content of artificial sand when mixing concrete. However, during the use of the current device for measuring the moisture content of artificial sand, the capacitive measuring head component of the device is generally fixed by bolts. When it fails and needs to be repaired later, the operation is more troublesome. Therefore, we proposed an online moisture content measurement device based on edge effect to solve the above problems.
