What size defects can be detected with TIP?
By applying the rule of one measurement location (Thermal Wire® cable or CSL-type access tube) in the cross section for each foot (300 mm) of shaft diameter, the zone of detection becomes dependent on the size of the anomaly. Multiple tubes or Thermal Wire cables can detect larger anomalies. Closer cables or access tubes are more apt to detecting smaller anomalies. Generally, engineers can detect a 10% cross section anomaly with multiple Thermal Wire cables or access tubes. Otherwise, defects of 5% of the cross section are easily located.
