RAEM1 Datasheet

Product catalog summary

Introduction
The RAEM1 is a single-channel IoT-AE system designed for remote, unattended acoustic emission (AE) monitoring and non-destructive testing. It integrates an AE sensor, data acquisition, processing, and transmission modules into a compact cylinder, suitable for long-term condition monitoring applications.

Working Principle
The system uses an AE sensor to convert acoustic wave signals from materials into electrical signals via the piezoelectric effect. These signals are amplified by a built-in preamplifier to enhance the signal-to-noise ratio, facilitating transmission to the RAEM1. The RAEM1 performs A/D conversion, processes, and analyzes the signals, then transmits the results to computers or cloud servers through wired or wireless communication.

Applications
RAEM1 is used for real-time monitoring of various conditions such as cracking, corrosion, leakage, wear, lubrication, and other defects. Typical applications include bridge wire break monitoring, rotating machine condition monitoring, structural health monitoring, valve leak monitoring, welding crack monitoring, bolts tightness monitoring, and cutting tool condition monitoring.

Features

m mQAWRUMS RAEM1 - Single Channel loT-AE System RAEM1 Introduction RAEM1 system is a complete full function loT-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 modules in one small cylinder. • Single channel system, flexible installation • Wired and wireless communication • Real-time automatic acquisition and transmission • Threshold or time triggering RAEM1 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. The typical applications are: • Bridge wire break monitoring • Rotating machine condition monitoring • Structural health monitoring • Valve leak monitoring • Welding crack monitoring • Bolts tightness monitoring • Cutting tool condition monitoring The AE sensor converts the acoustic waves signal of material into electrical signals through piezoelectric effect, and the built-in preamplifier amplifies the electrical signals from the sensor to increase the signal-to-noise ratio of the signal to facilitate signal transmission to RAEM1 via a coax cable. The RAEM1 performs A/D conversion, processing and analysis of the signal, and then transmit the result data to computer/cloud/servers via wired or wireless communication methods.
