Assessment and Verification System for AE PD Detectors

Key Features:

•  Comprehensive assessment:The system can comprehensively assess and verify the functionality and performance of AE 

PD detectors, including sensitivity, linearity, frequency band, sampling continuity, pulse counting, pattern recognition & 

diagnosis, and more.

•  Acoustic pulse generator:Generates pulses and simulated signals with adjustable amplitude, frequency, and interval.

•  Professional-grade components:The acoustic transducer for verification purpose has wide frequency response band (10 ~ 

300kHz) with flat amplitude-frequency curve within the frequency band.The acoustic testing platform is made of A36 hot rolled 

steel, which has consistent attenuation coefficient on each frequency band.

•  Discharge pattern simulation:Simulates typical discharge patterns including tip discharge, particle discharge, floating 

discharge, air-gap discharge, and creeping discharge.

•  Pulse counting verification:Generates pulses with fixed or random intervals to verify the continuity of sampling and the pulse 

count functionality.

•  Automated testing:Highly automated all-in-one software can perform all testing items and generate test reports with one 

click.

•  Data storage:Can store the records of all assessed instruments for diagnosis and analysis.
