Intrinsically Safe Acoustic Emission Sensors
China Ex-certified AE sensors for hazardous-area monitoring applications
Certification Notice
Qawrums intrinsically safe acoustic emission sensors have obtained explosion-protection certification from a Chinese authorized certification body. The current certification applies to the Chinese certification scope and standards listed in the certificate.
At present, these models are not certified under ATEX, IECEx, UL, CSA, or other international hazardous-location certification schemes. For projects outside China, please confirm local certification requirements before selecting or installing intrinsically safe AE sensors.
Intrinsically safe acoustic emission sensors are designed for AE testing and monitoring applications where flammable gas, vapor, petrochemical processes, or other hazardous-area conditions may be present. They are commonly used for storage tanks, pressure vessels, pipelines, valves, petrochemical equipment, and industrial facilities where safety requirements must be considered.
Qawrums intrinsically safe AE sensors have obtained explosion-protection certification from a Chinese authorized certification body. The certification scope, applicable standards, Ex marking, temperature class, and use conditions should be confirmed according to the official certificate before project selection.
For international projects, please note that these models currently do not hold ATEX, IECEx, UL, CSA, or other international hazardous-location certifications. If your project requires a specific regional certification, please contact us before selection so we can review the application requirements and provide suitable technical guidance.
