Ultrasonic High-Temperature Transducers

High Precision Measurement in Extreme Conditions

Important Note: The T-04X-XXXX and T-21X-XXXX high-temperature transducer models are now part of the Ultrasonic High-Temperature Transducer Series. All specifications, comparisons, and pricing for this series are provided below.

Checkline’s high-temperature dual-element transducers are engineered for accurate wall thickness measurement on hot surfaces. Available in versions rated up to 335°C (635°F) or 482°C (900°F), these transducers ensure precise readings even in demanding environments.

They are offered in ¼" and ½" sizes, with frequency options of 2.25 MHz and 5 MHz. Two connection types are available: a potted version with a fixed cable and a microdot version for use with a detachable cable (not included). These transducers are ideal for industrial inspections requiring reliable measurement performance at elevated temperatures.

Key Features:

High-Temperature Performance: Designed to maintain stability and accuracy when measuring at elevated temperatures up to 482°C.
Versatile Applications: Suitable for measuring metal and glass surfaces, with or without coatings, across a range of industrial sectors including manufacturing, energy and process engineering.
Size and Frequency Options: Available in ¼" and ½" sizes with frequencies of 2.25 MHz or 5 MHz to meet diverse inspection needs.
High-Damping Variants: Offered in Standard and High-Damping versions, optimised for Echo-Echo measurements through coatings.
Connection Types: Choice of potted connector with fixed cable or microdot connector for use with detachable cables.

Key Benefits:

Exceptional Temperature Capability: Performs accurate and consistent measurements in extreme environments up to 482°C, making it indispensable for high-temperature testing applications.
Enhanced Precision: Optimised frequency design enables detection of fine details and ensures reliable, repeatable results.
Durable Construction: Built for intensive use in harsh industrial environments, offering long service life and minimal maintenance.

Dimensions

High-Temperature Transducers

The high-temperature dual-element transducers feature a robust design optimised for reliable ultrasonic measurement on hot surfaces. The housing length is 107.5 mm, with diameters of 11.7 mm and 17.9 mm depending on the model (1/4" or 1/2").

Two connector options are available:

Encapsulated connector: Fixed-cable design.

Microdot connector: Detachable cable interface for flexible operation and easy replacement.

Both versions feature dual-element transducers and are available in 1/4“ (11.7 mm) and 1/2” (17.9 mm) sizes. These dimensions provide a stable contact area for accurate thickness measurements in high-temperature applications.

All dimensions are shown in millimeters (mm).

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.
