1/4" Ultrasonic Dual Element Transducers with potted connection

Important Note: The T-102-XXXX dual element transducer models are now part of the 1/4" Ultrasonic Dual Element Transducer series. All specifications, comparisons, and pricing for this series are provided below.

The 1/4" ultrasonic dual-element transducers from Checkline are engineered for high-precision thickness measurement in small or curved areas. Featuring side-mounted potted connectors and a 13.5 mm (0.53 inch) crystal diameter, these probes are ideal for applications requiring compact size and maximum manoeuvrability.

These transducers are available in multiple configurations, including high-damped (HD), composite, coating thickness (CT) and standard designs, with frequencies from 2.25 MHz to 10 MHz. They are compatible with a wide range of ultrasonic thickness gauges, including models supporting Pulse-Echo (P-E), Echo-Echo (E-E), Coating Thickness (CT), and Echo-Echo-Verify (E-EV) modes.

Key Features (varies by model):

Compact 1/4" Diameter: Ideal for tight access points and small-radius curved surfaces.
Potted Side-Mounted Connector: Provides secure signal integrity in harsh environments and offers a low-profile cable exit.
Multiple Frequency Options: Available from 2.25 MHz to 10 MHz for deeper penetration or enhanced resolution, depending on application.
Transducer Variants: Choose between standard, composite high-temp, or coating-optimised configurations.
Gauge Compatibility: Suitable for Checkline TI-MMX, TI-CMX and TI-25 series thickness gauges (see model-specific pairing).

Key Benefits:

Precision in Small Spaces: Small-diameter probe head delivers better contact on limited or curved test areas.
Application Flexibility: Suitable for a wide range of materials, from metals to plastics, across different gauge models.
Durable Design: Potted cable design improves strain relief and resistance to wear in industrial use.
Optimised Signal Quality: Composite and high-damped versions offer better resolution and accuracy on coated or thin materials.

This series of 1/4" dual-element transducers is the preferred choice for operators needing compact, durable, and precise probes for demanding ultrasonic wall thickness applications.

Dimensions

1/4" Dual-Element Transducer:

Designed for high-precision measurement in confined spaces, this 1/4" dual-element transducer offers the following key dimensions:

Face diameter: 11.8 mm – suitable for tight-radius curved surfaces and small measurement areas.
Head length: 15.8 mm – measured from face to connector base, excluding cable.
Total probe diameter: 16.2 mm – vertical size of the transducer housing.
Total probe length: 25,3 mm

These compact dimensions are ideal for applications requiring access to restricted or curved surfaces, ensuring optimal coupling and measurement stability with most ultrasonic thickness gauges.

TI-25 Series Wall Thickness Gauges

Memory & Data Logging: DLX and DLXT models feature onboard memory capable of storing up to 10,000 readings.
Accessory Compatibility: Compatible with a wide range of calibration blocks, couplants, and alternative transducers.
Warranty: 5-year warranty on the gauge, and 90 days on the transducer.
