TECHNICAL MANUAL
- Version: 1.0.1 10/
- April/2024
Structural Construction
- RAEM2 is an all-in-one condition monitoring system that integrates an acoustic emission sensor, battery, data acquisition module, and communication module into a small aluminum alloy cylinder housing with a magnet built into the bottom so RAEM2 can be magnetized to the surface of a ferromagnetic material. RAEM2 supports a variety of communication methods, such as 4G or LoRa, with Bluetooth short-range local inspection. The IoT cloud platform is used for remote data monitoring and parameter configuration.
- RAEM2 is time-triggered. The device automatically wakes up to collect data based on the configured sleep time. Independent of computers with high reliability, suitable for long term unattended condition monitoring

Technical Features
Application Introduction
- The RAEM2 monitoring system is suitable for rotating bearing condition monitoring, valve pipeline leakage monitoring, tool wear monitoring, transformer partial discharge monitoring, wind turbine bearing condition monitoring.
Pipeline and valve cracking and leakage monitoring:
- Pipelines and valves often suffer from corrosion and leakage after long-term operation. Without effective detection in the early stage, small corrosion or leakage will grow rapidly and eventually lead to major losses. RAEM2 monitoring system is suitable for monitoring steady-state signals. It can 365-day continuously online monitoring to identify pipeline or valve leakage in early stage.
Acoustic wave (acoustic emission) monitoring of rotating equipment:
- RAEM2 remote monitoring system collects and processes the acoustic emission signals of each component of the rotating equipment, and then upload data to Cloud Platform through LoRa and 4G. Users can do onsite inspections through Bluetooth APP on their mobile phone, or view real-time data through the cloud platform to remote monitor the status of the rotating equipment. (Damage status, lubrication status, etc.).
