摘要:
A system and method for inspecting a tube comprising a telemetry module, a centralizing module, an inspection device, a differential amplifier, a sensor array, and a service device. In embodiments, a tube inspection device may comprise a sensor array. The sensor array may further comprise a center receiver coil, a ferri-core, a peripheral receiver, and a transmitter coil. A method for inspection a tube may comprise inserting an inspection device into a tube, energizing a sensory array, inducing an eddy current within the tubing, and measuring voltage with a center receiver coil and a peripheral receiver of the sensor array.
