DeltaTherm Products
The DeltaTherm system is based on thermoelasticity. Simply stated…when a solid body is stressed it gets slightly hotter or slightly colder. Hotter when it’s in compression and colder when it’s in tension. That’s Thermoelasticity!
With DeltaTherm, very sensitive infrared cameras are mated with special high-speed digital electronics to measure the slight temperature perturbations. The result is a full-field stress map in just seconds!
Key Points about Thermoelasticity
- Full-field
- Simple flat black paint preparation
- Sum of the principal stresses
- Requires dynamic loading (cyclic loading in load frame)
- View at any angle
Key Advances of DeltaTherm
- IR array camera based – images in seconds
- Versatile software
- Portable
DeltaTherm technical specifications vary depending on the system (IR camera head). We’re happy to discuss detailed technical specifications and help match a system to your specific application. Simply contact Stress Photonics via our online contact form or call us at (608) 224-1230.
DeltaTherm
Thermoelastic Stress Analysis (TSA)
The DeltaTherm by Stress Photonics is a full-field, non-contacting, imaging system used to characterize the behavior of materials and structures undergoing stress. Using planar array infrared detectors and high-speed data acquisition and image processing, DeltaTherm creates near real-time images of surface temperature variations to a resolution of 0.001 degree C. The images provide an excellent visual correlation of stresses caused by loading on a structure.
Image Stresses in Just Seconds!
DeltaTherm is a unique IR differential thermography system suited to Thermoelastic Stress Analysis (TSA) and Thermal Nondestructive Evaluation (TNDE). By coupling special high-speed image processing electronics with a high-performance infrared array detector, it is now possible to image stresses in just seconds!
Simple User Interface
Detailed analysis and high quality presentation is performed using Stress Photonics’ DeltaVision™ software. The software allows DeltaTherm users to take advantage of powerful Windows software and network resources to process and present data quickly and easily.
