Dakota NDT — T1042700 Dual-Element Transducer

5.0 MHz, 1/2 in Dual-Element Ultrasonic Transducer, High-Damped, Potted Side Entry
SKU: T1042700

Overview

The Dakota NDT T1042700 is a 5.0 MHz dual-element ultrasonic transducer designed for corrosion monitoring, remaining-wall measurement, and general ultrasonic thickness-gauging applications.

Its 1/2 in contact size provides a practical balance between acoustic energy, coupling stability, and surface coverage, making it suitable for common industrial components such as piping, tanks, pressure vessels, plates, and structural materials.

The transducer features a high-damped (HD) construction that helps shorten the ultrasonic pulse and reduce ringing. This supports improved near-surface resolution and clearer separation of closely spaced echoes.

A permanently potted side-entry cable provides a secure probe connection while routing the cable away from the top of the transducer for convenient field and maintenance use.

What's Included

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

Box Dimensions & Shipping Weight (Estimated)

Key Specifications

Performance Features

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

High-Damped Construction
Helps reduce ringing and shorten pulse duration, supporting improved response near the inspection surface and better echo separation.

Dual-Element Design
Separate transmitting and receiving elements support reliable measurements on surfaces affected by corrosion, erosion, pitting, or general material loss.

1/2 in Contact Size
Provides stable coupling and useful acoustic energy for pipes, tanks, vessels, plates, and other common industrial components.

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 with positioning in confined or low-clearance inspection locations.

High-Damped Design Advantages

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

• Reduced transducer ringing

• Shorter ultrasonic pulse duration

• Improved near-surface resolution

• Better separation of closely spaced echoes

• More distinct back-wall response

• Improved performance on thinner sections

• Useful response for localized corrosion evaluation

• Enhanced measurement clarity in suitable materials

Actual performance depends on the material, thickness, surface condition, couplant, gauge settings, 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 area

• 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

Care and Handling

• Avoid dropping or striking the transducer

• Keep the probe face clean

• Remove couplant after inspection

• 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 sharp bends, twisting, or pinching of the cable

• Protect the transducer from excessive temperatures unless specifically rated for elevated-temperature service

• Store in a clean, dry location

• Replace the probe if wear or damage affects measurement repeatability
