摘要: A portable digital ultrasonic monitoring system and method for use by an operator in detecting the waves temperature variations produced sources such as leaks pipes, arcing, electrical corona machinery defects is provided. The includes a microprocessor based hand held elongate housing that digitally analyzes stores information received from its sensors. provides referenced decibel output reading of signal strength signals. In addition, heterodyned type audio related to sensed signals provided through pair headphones. device has user input keys allow select variety different operating modes. display displays readings depending upon mode device.
