ADVANCEMENTS IN NETWORK-DISTRIBUTED ULTRASONIC SENSORS

摘要

Industrial plant ultrasonic testing applications, such as those typical at refineries, chemical, nuclear and fossil power plants, sometimes require expensive, bulky or complicated instrumentation that does not easily lend itself to portability. In some of those cases, including AUT Imaging, it is impractical or undesirable to bring the UT instrument very close to the area of test. These applications therefore require the use of very long (> 150' or 45.7m) cables. If dual-element probes or multi-element transducer arrays are needed for area coverage or other reasons, then the quantity and complexity of the cable bundles become both expensive and bulky to manage. Cable breakage, wear-and-tear also become issues of availability and economics.
