TEA/TEB – Attached/Detachable

The eddy current bobbin probes are lightweight, economical, but solidly built probes with the coils protected with a plastic sleeve and stainless steel wear guides at front and rear ends. They are ideal for the inspection of heaters, coolers, and heat exchangers.

Features

• Lightweight, solidly built.
• Coils protected by a plastic sleeve.
• An economical solution.
• Stainless steel wear guides at front and rear ends.
• Ideal for heaters, coolers, heat exchangers, and more.

Faster is better – Available for shortest delivery times
The probes listed below are regularly stocked for quick delivery. If the probe you require is not indicated, consider the alternate options with slight diameter and frequency variations, which won’t affect the quality of your results.

TEC/TED – Attached/Detachable

The eddy current air conditioner probes offer solid construction for durability. They include a differential bobbin set and a circumferentially sensitive pancake array. They offer better detection capability at the transition zone in addition to detection of circumferentially oriented cracks.

Recommendations

Heavy tube wall: TEC and TED probes are not recommended for wall thicknesses over 2.0 mm (0.08 in.), because the inspection may be limited to the inside. Note that these probes require the TE-ADP-004 adapter.

Features

• Solid construction for durability.
• Includes a differential bobbin set and a circumferentially-sensitive pancake array.
• Detection of circumferentially-oriented cracks.
• Better detection capability in the transition zone.
• Ideal for air-conditioner tubing.

Probe design

The air conditioning probe combines pancake arrays with standard differential bobbins for detection of circumferentially oriented cracks.

TEE/TEF – Attached/Detachable

The eddy current titanium probes offer ultimate durability with titanium protective cover for the coils and stainless steel wear guides at front and rear ends. They are ideal for heaters, coolers, and heat exchangers.

Features

• Ultimate durability.
• Titanium protective cover for coils.
• Stainless steel wear guides at the front and rear ends.
• Ideal for heaters, coolers, and heat exchangers.

TEG – Attached

The eddy current flexible probes offer solid stainless steel construction for durability and titanium protective cover for the coils. They are designed to inspect tight U-bend (as low as 50 mm curvature radius).

Recommendations

TEG probes are designed to inspect tight U-bends with radius of curvatures as low as 51 mm (2 in.). These probes are designed to inspect one half of the U-bend (90°) from each side of the tube.

Features

• Solid stainless steel construction for durability.
• Titanium protective cover for coils.
• Tight U-bend capability (with curvature radius as low as 50 mm [2 in.]).

TEK/TEL – Attached/Detachable

The eddy current high-resolution probes are lightweight, but solidly built probes with the coils protected with a plastic sleeve and stainless steel wear guides at front and rear ends. Their narrow coils make them ideal for thin tubing inspection such as titanium tubing.

Features

• Narrow coil, ideal for thin tubing inspection such as titanium tubing.
• Lightweight, solidly built.
• Coils protected by a plastic sleeve.
• Stainless steel wear guides at the front and rear ends.

TER – Detachable

The eddy current Airgun probes are extremely lightweight. It is designed to work with the MPP04-01 Airgun probe pusher-puller. It features a grooved design to reduce pushing force in tube end and to improve durability. It is ideal for steam condensers, coolers, and heat exchangers.

Recommendations

TER probes are designed be used with the Airgun scanner to speed up ECT inspection (4 m/s to 6 m/s push speed, and 2 m/s encoded pull speed).

Features

• Extra lightweight.
• Designed to work with the MPP04-01 Airgun probe pusher-puller.
• Grooved design to reduce pushing force in the tube end and improve durability.
• Ideal for steam condensers, coolers, and heat exchangers.

TEO – Attached

CARTER super magnetic bias probes offer an ultradurable construction with hardened steel wear surface for a long life in harsh environments. These probes are designed to suppress permeability noise in mildly ferritic material such as Monel, 3RE60, SEA‑CURE, and 400-series stainless.

Recommendations

TEO are limited to mildly ferritic tube inspection of thicknesses below 1.5 mm. In other contexts, the probe is not likely to provide adequate magnetic saturation of the tube wall.

Features

• Super magnetic bias.
• Ultra durable construction.
• Hardened steel wear surface for long life even in harsh environments.
• Ideal for suppressing permeability noise in mildly ferritic materials, including Monel, 3RE60, nickel, SEA-CURE, Duplex and 400-series stainless steel.
