NM01BEX02C
This is a specialized ultrasonic transducer, a critical component in non-destructive testing (NDT), manufactured by NDT Systems. It is designed to perform precise inspections using high-frequency ultrasonic waves. The transducer's specific characteristics make it particularly suitable for applications demanding high resolution and access to restricted areas.
Key Features and Functionality:
Ultrasonic Wave Generation and Reception:
At its core, this device functions as an electroacoustic transducer. It utilizes the piezoelectric effect to convert electrical impulses into ultrasonic waves, and conversely, to transform received ultrasonic echoes back into electrical signals. This process enables the detection of internal discontinuities, flaws, or variations in material thickness.
"Pencil" Style Design for Enhanced Accessibility:
The "pencil" designation refers to the transducer's slender, cylindrical form factor. This design is crucial for inspections in environments where space is limited. It allows technicians to navigate complex geometries and reach areas that would be inaccessible to larger transducers. This is very useful in aerospace applications, and in tight weld inspections.
High-Frequency Operation at 12 MHz:
The 12 MHz center frequency signifies that the transducer emits and receives ultrasonic waves at a relatively high frequency. This characteristic provides superior resolution, enabling the detection of minute defects. However, it's important to note that higher frequencies also result in reduced penetration depth. Therefore, this transducer is optimally suited for inspections of thin materials or for the detection of near-surface flaws.
Precise 0.187" Element Diameter:
The diameter of the piezoelectric element plays a significant role in determining the ultrasonic beam's characteristics. This specific dimension balances the trade-off between resolution and sensitivity, providing a focused beam for accurate defect detection.
Integrated Permanent Delay Line ("Perm Delay") for Near-Surface Inspection:
The inclusion of a permanent delay line is a key feature that enhances the transducer's ability to inspect near-surface regions. By introducing a time delay, the initial pulse and near-field reflections are separated from the echoes originating from within the test material. This improves the signal-to-noise ratio and enables more accurate detection of shallow defects.
NDT Systems Quality and Reliability:
Manufactured by NDT Systems, a reputable provider of NDT equipment, this transducer adheres to stringent quality control standards. This ensures reliable performance and accurate inspection results.
Application Considerations:
This transducer is ideal for applications in industries such as aerospace, manufacturing, and quality control, where precise defect detection is paramount.
It's particularly well-suited for inspections of welds, thin-walled components, and other applications requiring high resolution in confined spaces.
