Dakota NDT — T-101-4000 Dual-Element Transducer

10.0 MHz, 3/16 in Diameter Dual-Element Ultrasonic Transducer, Potted Side Entry
SKU: T-101-4000

Overview

The Dakota NDT T-101-4000 is a compact 10.0 MHz dual-element ultrasonic transducer designed for high-resolution thickness measurement and corrosion-monitoring applications. Its high operating frequency and small 3/16 in diameter make it well suited for thin materials, small components, localized inspection areas, and applications where access is limited.

The dual-element design uses separate transmitting and receiving elements, helping improve near-surface performance and providing reliable readings on suitable materials where precise thickness measurements are required.

A permanently potted side-entry cable provides a secure probe connection while routing the cable away from the top of the transducer. This configuration supports convenient positioning on small components, curved surfaces, and restricted inspection areas.

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

10.0 MHz High-Frequency Operation
Provides high ultrasonic resolution for suitable thin materials and precision thickness-measurement applications.

Dual-Element Construction
Separate transmitting and receiving elements improve near-surface response and support reliable thickness gauging.

3/16 in Compact Probe Diameter
The small contact footprint supports inspection of narrow surfaces, small-diameter components, curved geometries, and localized areas.

Potted Cable Design
The permanently attached cable eliminates a detachable probe-side connector and provides a secure transition between the transducer and cable.

Side-Entry Configuration
Routes the cable away from the top of the transducer, helping with probe positioning in confined or low-clearance inspection areas.

Precision Measurement Capability
The combination of high frequency and compact diameter makes the probe well suited for applications where resolution and localized contact are important.

User-Friendly Design

• Compact 3/16 in probe footprint

• Suitable for small and curved components

• High-frequency response supports detailed measurements

• Dual-element configuration supports corrosion-monitoring workflows

High-Frequency Inspection Advantages

The 10.0 MHz configuration can provide several benefits in suitable applications:

• Improved resolution on thin materials

• Better separation of closely spaced echoes

• Enhanced near-surface measurement capability

• Suitable response for small components

• Precise localized thickness measurements

• Practical performance where lower-frequency probes provide insufficient resolution

Higher-frequency transducers generally provide less penetration than lower-frequency probes, so material thickness, attenuation, grain structure, and surface condition should be considered when selecting the transducer.

Inspection Guidelines

• Verify that the ultrasonic gauge supports 10.0 MHz dual-element transducers

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

• Apply an appropriate ultrasonic couplant

• Calibrate the instrument using a suitable reference standard

• Set or verify the correct material sound velocity

• Position the probe carefully on the inspection area

• Check the potted cable transition for damage

• Do not pull or carry the transducer by the cable

• Avoid sharp bends, pinching, or twisting of the cable

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

• Store in a clean, dry location

• Replace the probe if wear or damage affects measurement repeatability
