Innerspec’s latest EMAT solution for high-temperature thickness measurement operates in extreme conditions, withstanding temperatures up to 650°C, making it ideal for challenging environments. It is the first and only compact device capable of working with both EMAT and piezoelectric sensors. One of its most remarkable features is the exceptional Time-of-Flight measurement accuracy, achieving an astonishing precision of equal to or better than +/-0.0002” (0.005 mm) in spot testing.
CODA offers the most complete catalog of non-couplant sensors, including EMAT and DCUT. Among its key innovations are a reduced dead zone, a new dual EMAT sensor to detect internal corrosion, and an advanced algorithm for ultra-thin materials (0.1-0.2 mm). The applications of this system are as diverse as they are impressive, from spot thickness measurements to thickness grid analysis, encoded thickness mapping, and residual stress measurement.
High-performance solutions for various Techniques
CODA is a versatile instrument designed for both EMAT applications and conventional Ultrasonic Testing techniques, suitable for:
• Thickness Measurement and Flaw Detection
• Corrosion Mapping (encoded)
• Stress Measurement (train wheels, rails, plates, steel bridges)
• Bolt-load Measurement
What are the versions of CODA?
CODA is available in three versions which are CODA, CODA+, and CODA SM. All versions provide all EMAT and piezoelectric functionality. CODA+ with a single-axis encoder and CODA SM specifically designed for stress measurement applications.
- CODA: The base model provides all EMAT and piezoelectric functionality without an encoder.
- CODA+: It includes a one-axis encoder input for encoded Strip Charts and C-scans using a manual or an automated scanner.
- CODA SM - (Stress Measurement): Specifically designed for stress measurement, it permits to sequentially pulse a two-channel EMAT sensor using Innerspec’s proprietary technique. It is delivered with custom stress software and different positioning fixtures depending on the application.
The software is fully customizable, allowing for system updates and upgrades with additional applications tailored to specific inspection needs.
Leveraging the Advantages of EMAT Technique
The EMAT (Electromagnetic Acoustic Transducer) technique generates ultrasonic waves directly in the material, eliminating the need for couplant or physical contact with the part. This unique feature makes EMAT ideal for applications under challenging conditions, such as:
1. Extreme Temperatures:
CODA ensures accurate and reliable readings in temperatures ranging from -30°C to 650°C. The system can also be equipped with high-temperature handles and a Dual Element Piezo sensor for enhanced performance.
2. Coated and Rough Surfaces:
EMAT is unaffected by surface conditions, enabling inspection through coatings and on rough surfaces without requiring direct contact. It delivers consistent results even with a high lift-off distance, typically ranging from 0 to 3mm. In some cases, greater lift-off distances of up to 7mm can be achieved, depending on the material, sensor, and type of inspection.
3. Curved Parts:
Unlike piezoelectric sensors, which require perfect contact, EMAT offers a more flexible solution for inspecting curved surfaces. Its performance remains accurate and reliable, even when there are slight variations in probe angle, simplifying the inspection process.
Innerspec has developed a wide range of EMAT sensors for different particular applications, leading and pushing the boundaries of the EMAT technique. Additionally, CODA is compatible with the Innerspecs Dry Couple (DCUT) piezoelectric sensors.
A Tailored Solution for Every Application
Innerspec continually develops a wide range of sensors and accessories to maximize performance in the most demanding environments. CODA is compatible with over 20 EMAT and DCUT sensors from Innerspec, as well as conventional piezoelectric sensors from any manufacturer.
Innerspec’s EMAT and DCUT sensors, combined with scanners, positioners, and other accessories, are specifically designed to inspect a variety of materials in harsh industrial settings, ensuring reliable performance and adaptability across different applications.
CODA’s software allows flexibility in adjusting frequency, cycles, filters, and thickness algorithms to get the best signal quality.
Advanced, Tailor-made Software
CODA uses the Innerspec Technologies Operating Platform (ITOP) with NDT-WEB application software. Innerspec’s NDT-WEB technology permits accessing and operating the instrument from any phone, tablet, laptop, or desktop directly from a web browser, independently of the device’s Operating System, and without having to install potentially unsafe files or apps.
Connection to CODA is immediate through the built-in WiFi and/or Ethernet port. CODA’s software is fully customizable and can be updated or upgraded for specific applications. It also integrates with NDT-LINK, Innerspec’s cloud-based asset management platform, providing a central hub to manage users, update equipment, order spare parts, request support, and store data—all in one place.
With Wi-Fi/GSM connectivity and NDT-LINK, CODA enables easy communication and reporting through phones or tablets, offering a durable alternative to traditional flaw detectors with fixed screens.
In addition, the software offers a range of features to enhance workflow efficiency:
- Operator Mode: Switch to Operator Mode for a mobile-optimized interface with larger buttons and text, ideal for use on smartphones. Paired with CODA’s lightweight design and a harness, this mode simplifies inspections in confined or hard-to-reach spaces.
- Automatic Reporting: Easily customize reports by uploading your company logo and selecting the information to include, saving time on report generation.
