This TOFD ultrasonic transducer is an OLYMPUS-style, Microdot-connector probe designed for Time-of-Flight Diffraction (TOFD) testing. It is a highly damped, sensitive longitudinal-wave transducer intended for use with specialised TOFD wedges to generate refracted longitudinal waves in steel for crack detection and sizing applications.
The TOFD transducer is engineered for demanding ultrasonic testing applications where reliable resolution and sensitivity are important. Its composite-element construction provides broadband response and supports TOFD inspections involving welds, steel components, and other applications where accurate crack sizing is required.
This listing is for the probe only. TOFD wedge is not included unless specifically selected or stated in the order.

Features: TOFD Ultrasonic Probe
Highly Damped Longitudinal-Wave Design
The transducer uses a highly damped longitudinal-wave configuration designed to provide a clear ultrasonic response. This makes the probe suitable for TOFD applications where resolution and sensitivity are important for evaluating diffracted signals.
OLYMPUS Style Housing
The probe features an OLYMPUS-style housing, making it suitable for applications requiring this common industrial ultrasonic probe form factor. The housing style should not be interpreted as a claim that Olympus manufactured the transducer.
Microdot Connector
A Microdot connector is provided for the transducer connection. Buyers should verify the connector and instrument requirements before ordering to ensure the selected probe is appropriate for their ultrasonic testing setup.
Multiple Frequency Options
The TOFD transducer series is available across a range of frequencies from 2.25 MHz to 15 MHz, with different element sizes available depending on the selected variant.

Frequently Asked Questions
What is a TOFD ultrasonic transducer?
A TOFD ultrasonic transducer is a specialised ultrasonic probe used for Time-of-Flight Diffraction testing. It sends ultrasonic energy into a component and detects diffracted signals from flaw tips to help evaluate crack location and size.
What is the purpose of the TOFD wedge?
A specialised TOFD wedge is used with the transducer to introduce the appropriate refracted longitudinal wave into the test material, such as steel. The wedge is not included with this probe-only listing unless explicitly specified.
Does this probe use a Microdot connector?
Yes. This TOFD transducer is specified with a Microdot connector.
What frequencies are available?
The listed TOFD transducer variants range from 2.25 MHz to 15 MHz, including 2.25 MHz, 5 MHz, 10 MHz, and 15 MHz options.
What element sizes are available?
The available variants use element sizes from 3 mm to 12 mm, depending on the selected model.
Is the TOFD wedge included?
No. This listing is for the transducer probe only. A suitable specialised TOFD wedge is required for the intended refracted-wave inspection configuration.
What materials can this TOFD probe inspect?
The stated application is for generating refracted longitudinal waves in steel for TOFD crack-sizing applications. Buyers should verify the probe, wedge, instrument, and material configuration for their specific inspection procedure.
