Dakota NDT — T-101-2700 Dual-Element Transducer

5.0 MHz, 3/16 in Dual-Element Ultrasonic Transducer, High-Damped, Potted Side Entry
SKU: T-101-2700

Overview

The Dakota NDT T-101-2700 is a compact 5.0 MHz dual-element ultrasonic transducer designed for corrosion monitoring, remaining-wall measurement, and general ultrasonic thickness-gauging applications. Its 3/16 in contact size provides a small inspection footprint for localized measurements, small-diameter components, curved surfaces, and areas where probe access is limited.

The transducer incorporates a high-damped (HD) design to help shorten the ultrasonic pulse and improve separation between closely spaced echoes. This makes the probe well suited for applications requiring good near-surface response and dependable measurement resolution.

Its dual-element configuration uses separate transmitting and receiving elements, while the permanently potted side-entry cable provides a secure probe connection and keeps cable routing away from the top of the transducer for convenient positioning during field inspections.

What's Included

Note: Ultrasonic thickness gauge, couplant, calibration standards, adapters, and other accessories are not included unless specified separately.

Key Specifications

Performance Features

5.0 MHz Operating Frequency
Provides a practical balance between ultrasonic penetration and measurement resolution for a broad range of industrial thickness-gauging applications.

High-Damped Construction
Helps shorten the ultrasonic pulse and reduce ringing, supporting improved separation between closely spaced echoes and better near-surface response.

Dual-Element Design
Separate transmitting and receiving elements help provide dependable measurements on surfaces affected by corrosion, erosion, pitting, or general service wear.

3/16 in Compact Contact Area
The small inspection footprint supports measurements on narrow surfaces, small-diameter components, curved geometries, and localized corrosion areas.

Potted Cable Configuration
The permanently attached cable provides a secure probe-side connection and eliminates the need for a detachable connector at the transducer.

Side-Entry Cable
Routes the cable away from the top of the probe, helping technicians position the transducer in confined or low-clearance inspection areas.

High-Damped Design Advantages

The HD configuration can provide useful performance benefits in suitable ultrasonic applications:

• Shorter ultrasonic pulse duration

• Reduced transducer ringing

• Improved near-surface resolution

• Better echo separation

• More distinct back-wall response

• Useful performance on thinner sections

• Improved response in localized corrosion measurements

• More precise evaluation where closely spaced echoes are present

Actual results depend on the material, thickness, surface condition, gauge settings, couplant, and calibration procedure.

Inspection Guidelines

• Verify that the ultrasonic gauge supports 5.0 MHz dual-element transducers

• Clean loose scale, dirt, and contamination from the inspection point

• Apply an appropriate ultrasonic couplant

• Calibrate the instrument using a known reference thickness

• Verify the correct material sound velocity

• Position the probe firmly against the inspection surface

• Maintain consistent probe pressure and orientation

• Obtain a stable and repeatable thickness reading

• Take multiple measurements where corrosion is irregular

• Recalibrate periodically according to the written inspection procedure

Care and Handling

• Avoid dropping or striking the transducer

• Keep the probe face clean and free from hardened couplant

• Inspect the contact surface regularly for wear

• Check the potted cable transition for damage

• Do not pull or carry the probe by the cable

• Avoid sharply bending, twisting, or pinching the cable

• Protect the probe from excessive temperatures unless specifically rated for high-temperature use

• Remove couplant residue after inspection

• Store in a clean, dry location

• Replace the transducer when wear or damage affects measurement repeatability
