Abstract
A vibration sensor fixing device with a weather-proof function is composed of two major parts: a multifunctional base and a weather-proof fixing hood. Compared with other sensor fixing devices, factors influencing sensor measurement and layout are considered comprehensively. First, the device is weather-proof, a sensor connecting line is fixed by a moving cover plate of the fixing device, the fixing hood can further isolate the influence of the external environment, so that a sensor is protected, and data measurement is not interfered by weather. Secondly, the multifunctional base adopted provides a variety of modes of connection with a tested object in structure, and the base can be fixed by an adhesive, magnetic or mechanical fixing method according to the features of the tested structure and the field environment; and a sensor can be directly and reliably in contact with the tested object through a vertical pressing device and a reversed sensor mounting hole of the base. As the way of fixing is flexible and convenient and damage to the sensor is avoided, the fixing effect of the sensor is guaranteed effectively.
