Compatible with a variety of communication methods, long transmission distance, fast speed. Compact design and easy installation.
RAEM1 system is a complete full function IIoT-AE system designed for remote unattended acoustic wave (acoustic emission) long term non-destructive testing and condition monitoring applications. RAEM1 is a single channel AE monitoring system integrated with AE sensor, data acquisition, processing and transmission in one small cylinder. It can real-time monitor cracking, corrosion, leakage, wears, lubrication and other failures or defects in the early stage to predict and alarm early fault detection and maintenance.
RAEM1 System and Application Overview
System Principles and Features:
RAEM1 Principle and Data Flow
The RAEM1 package consists of an AE sensor, built-in modules for data acquisition and analysis and transmission, a power adaptor and some accessories. When the RAEM1 detects acoustic waves on the sensor, it will automatically process, analyze and transmit the result data to the desired terminals.
- Wireless connection, reduce the cable connection workload and save cable consumption.
- Simple installation, RAEM1 magnetic suction base can be directly sucked on the equipment.
- Real-time monitoring, acoustic wave processing software can carry out real-time display and processing of signal data.
- Various acoustic wave parameters, arrival time, amplitude, counts, energy, rise time, rise counts, duration, RMS, ASL
- Smart alarming, if abnormal activities are detected, it will automatically send out alarm notifications via SMS or emails with the device information and alarm levels.
- Made of aluminum alloy shell, compact in size, light in weight, sturdy and resistant to impacts, easy to carry.

- The RAEM1 is based on the Linux system and has high feasibility, stability, and security;
- Multiple acquisition methods: In terms of sampling modes, there are the envelope mode and continuous model; according to sampling time differences, there are interval sampling, continuous sampling and timing sampling modes;
- Flexible channel combination: can be used as a single channel or networked with multiple RAEM1 on site to form a multi-channel system for real-time monitoring of large or oversized equipment and facilities;
- Multiple triggering methods: threshold triggering, time triggering;
- Adopting 5G+2.4G WiFi module, balancing the transmission speed and range, with a maximum transmission speed of 120Mbps and a maximum transmission range of 100m;
- Using a 100Mbps Ethernet port, the maximum transmission speed can reach 100Mbps;
- built-in 64G SD card storage, which can be expanded to a maximum of 512GB for storing data without data loss due to power outage;
- The data can be uploaded to the cloud IoT platform for display and analysis (Alibaba Cloud, Qingcheng IoT cloud platform), or downloaded to the computer or directly sent to Qingcheng SWAE software for real-time analysis and processing;
- RAEM1 can be used as the desktop AE detector for on-site testing applications as well as remote unattended condition monitoring system for long-term monitoring applications.
RAEM1 is a single channel AE monitoring system integrated with acoustic emission signals sensing, acquisition, processing, analysis and transmission all-in-one. The RAEM1 package consists of a RAEM1 cylinder, an AE sensor, a power adaptor, antenna and some accessories.
Basic RAEM1 hardware and dimension
Based on the application and the actual site environment and requirements, the appropriate matching sensor and the communication methods are selected from all available options when ordering. The phantom power, analog filter and communication modules are hardware embedded so they cannot be modified by software after manufacturing. It is recommended to only connect the original matching sensor types to the RAEM1.
RAEM1 can be used as a remote unattended monitoring system using wireless communications.
RAEM1 can also be used as a single channel desktop measuring device for AE testing.
Multiple RAEM1 can form a multi-channel AE system for AE testing of large equipment.
