ThermoESA System

Video 1 – ThermoESA sensor

The ThermoESA is a Thermoelastic Stress Analysis (TSA) measurement system that offers the advanced, in-situ, stress visualisation capability of a high-end R&D instrument with the ruggedness, versatility, and ease-of-use of an industrial tool. The innovative approach behind the ThermoESA is through the use of one, compact, and rugged uncooled LWIR (Long Wave Infrared) camera together with sophisticated signal processing, and custom-built timing electronics to achieve a ground-breaking thermal sensitivity of less than 1 mK (millikelvin).

Through using the correlation “lock-in” technique, the ThermoESA has the ability to capture high signal-to-noise (SNR) images, which serves as a comprehensive measurement for Finite Element Model (FEM) validation. This drives better design and engineering outcomes as FEMs can be refined and validated early in the design/manufacturing process.

Packaged with the ThermoESA system is the powerful MiTE Suite software package, offering a comprehensive set of tools for advanced stress imaging and analysis.

The MiTE Suite delivers a range of features, including:

  • Full complex-valued thermoelastic response
  • Real-time display of visual and infrared image
  • Semi real-time display (user selectable frame rate) of thermoelastic effect
  • Plotting functions
  • Point and RoI metrics
  • Stress & temperature change calibration
