faults in the diameter of the cable (lumps or neckdowns). LN Detectors are
self-contained instruments with fast response circuitry and solid-state infrared light
sources that allow instant detection of changes in the cable diameter. The signal
processing and intelligence is built into the gauge head and outputs can be taken
straight from the LN Detector that trigger alarms or marking devices when faults are
detected.
Infrared Fault Detection Principle
The infrared light source and optics inside the gauge head create a continuous “curtain”
of light across the cable. The cable blocks a certain amount of the light, and that light registers
a voltage level at the receiver. When a short variation in the diameter occurs, the amount of light
at the receiver changes. The sensitivity to light changes is user definable and when the change is
enough to cross the threshold, a fault is triggered.
