RFT Double-Receiver Probes
Dual-receiver RFT probes provide four analysis channels to improve defect detection near support plates and tubesheets in ferromagnetic tubing.
Product overview
RFT Double-Receiver Probes use lead and trail receiver sets to provide both absolute and differential signals at each end of the probe. This arrangement gives inspectors four channels for evaluating indications near external tube features, with onboard preamplifiers providing 30 dB gain.
The dual-receiver design is intended to increase probability of detection near support plates and tubesheets. These features can interfere with standard RFT probes, particularly in heat exchangers with numerous support plates. For tubes with an outside diameter greater than 1.5 inch (38.1 mm), the larger signal footprint is more susceptible to blockage by external features.
Designed for ferromagnetic tubing in heat exchangers and straight boilers, the probes target corrosion, erosion, wear and large pitting. Their waterproof, wear-resistant construction includes a highly kink-resistant cable. Probes with diameters under 20 mm have a stainless-steel sleeve, while those above 20.0 mm (0.787 in) use a lightweight advanced-polymer body.
Key capabilities
Dual receiver sets
Lead and trail receivers improve insight near external features such as support plates and tubesheets.
