Thermal mapping

For many industrial and commercial processes, temperature monitoring is essential to ensure operational safety and efficiency. Conventional electric temperature sensors can perform adequately if they are replaced often and are effectively shielded from EMI. However, they all suffer from the same inherent limitation: they can only measure temperature at a single point or location. Distributed temperature sensing technology provides a new level of insight into surface and ambient temperature distributions, allowing users to thermally map areas of interest, in real-time, with a spatial resolution as low as 1.6 mm. This level of data granularity can’t be achieved using traditional single-point temperature sensors. Due to its small size, chemical inertness, and immunity to electromagnetic interference, optical fiber can be installed in environments that alternative sensors cannot operate in. Processes that rely on maintaining temperature uniformity stand to benefit greatly from these capabilities, including:

  • Design and monitoring of temperature distribution
  • Cryogenic tank monitoring
  • Ice detection
  • Optimizing thermal design
  • Thermally mapping path of fluid for heat exchangers (radiators)
  • Chemical manufacturing
  • Understanding thermal gradients
  • Thermal characterization of electrical components and equipment
  • Validating computational fluid dynamic models
