Product Description

The wireless vibration sensor integrates STMicroelectronics' industrial-grade vibration sensor chip and can obtain the real-time acceleration signal/velocity/displacement/temperature signal of the device. Supports time domain analysis and frequency domain analysis of vibration data to obtain real-time vibration intensity and vibration frequency of the equipment under test. Through the self-developed wireless SCADA gateway for networking applications, data can be uploaded to the cloud platform or local server. The host computer software is used to calculate vibration parameters, display real-time data, display trend data, and provide historical data management and automatic reporting functions. Alarm prompts will be issued if vibration or AI prediction anomalies occur. It can be installed on the equipment shell and rigid base through magnetic attraction or screw fastening. Available scenarios: Scenarios that require preset maintenance of equipment.
