Wireless vibration sensor and system for isolating interference

The invention relates to the field of sensor structures, in particular to a wireless vibration sensor and system for isolating interference, which can effectively fix a detection element in the sensorand keep the detection accuracy. The wireless vibration sensor for isolating interference comprises a base, a piezoelectric core body and an isolation assembly, the base is provided with a cavity, the isolation assembly comprises an insulation gland, the piezoelectric core body is arranged in the cavity and fixed through the insulation gland, and the insulation gland is provided with a first wiring hole. The piezoelectric core body can be fixed in the base through the insulating gland, the piezoelectric core body is not prone to loosening due to long-time use through the physical characteristics of mechanical connection, maintenance is convenient, compared with a pouring sealant mode, the service life is longer, and the detection accuracy can be better kept. 本发明涉及传感器结构领域，尤其涉及一种隔离干扰的无线振动传感器及系统，可以有效固定传感器中的检测元件，保持检测
