Remote Field Testing

Remote Field Testing is an electromagnetic examination which utilizes the through transmission effect to produce a resulting field that is affected by anomalies. It is measured a few or more tube diameters away from the AC excitation source without any tube magnetization or saturation. The remote field phenomenon is an electromagnetic testing technique used primarily for in-service, baseline, or QC inspection of ferromagnetic tubing and piping.

Why Remote Field Testing?

  • Full Length Inspection

    This inspection consists of a full-length examination performed from the inside of the tubes with equal inner and outer surface discontinuity detection and sizing.



  • Probe Selection

    At Horizon Testing Inc. we strive to provide the best selection of RFT probes for specific applications. RFT probe design is affected by many considerations and variables.

    Probes are designed for specific applications and may, or may not, be suitable for testing other materials, sizes, or wall thickness.

    Preparation is advisable, and customers should consult and discuss component history with the inspector prior to the inspection.

  • Fast and Accurate

    Provides real-time results with high precision, allowing for quick identification of issues.

  • No Material Damage

    Completely non-invasive, making it suitable for critical applications where material integrity must be preserved.

How does it work?

We at Horizon Testing Inc. utilizes the Zetec MIZ-28 in conjunction with Carbon Steel Inspection (CSI), advanced design probes, remote field amplifier, and software. This inspection consists of a full-length examination performed from the inside of the tubes with equal inner and outer surface discontinuity detection and sizing. An alternating current is applied to an excitation coil which generates a strong electromagnetic field that propagates out of, and extends away from, the exciter along the tube length. The field then re-enters the tube wall axially from the exciter.

The inducer voltage is measured through the use of a detector coil, bobbin, or pancake that is placed in the remote field zone providing for a volumetric inspection with equal sensitivity to ID and OD anomalies of the tube. The sensor coils pick up the disturbance of the field due to the presence of any anomaly caused by corrosion, stress, foreign object, or mechanical vibration. The signal is measured relative to the X-axis in degrees which equates to flaw depth. The technology has the ability to display in a (X-Y) format.

This allows the data analysis to use pattern recognition for characterizing the signals. Typically, the analysis parameters are established where the phase or angular relationship of the signal is measured relative to the X-axis in degrees, which equates to flaw depth.
