THE CUSTOMER

The solution is for an innovative technology company utilising quantum cascade lasers in a variety of gas sensing applications. A quantum cascade laser is a mid infrared light source that can be used to interrogate the spectral fingerprint of a wide variety of small molecules, enabling quantitative detection of atmospheric constituents such as methane and nitrous oxide, and pollutants including NOx and carbon monoxide.

The Challenges:

  • Complex algorithms used to extract concentrations from spectral fingerprint data
  • Very fast response required to track rapid changes in concentrations
  • Data processing rates of >100 concentrations per second
  • Up to 12 gas types measured simultaneously
  • Measurement data communicated simultaneously over TCP/IP, RS232 and/or 4-20ma
  • Multi-threaded application requiring powerful multi-core processor

The Solution

  • A range of PC’s including 2U rack mount, Desktop & embedded versions to allow integration with variants of application end user systems
  • Different CPU’s used for individual systems ranging from Intel Atom to Intel Q9400 Core 2 Quad CPU giving the required performance and longevity
  • All components to full industrial specification to ensure reliable performance
  • SSD used in place of traditional HDD to improve reliability

The Outcome

  • Reliable, cost effective industrial and embedded PCs that meet requirements
  • Deployment in over 100 gas sensors in a variety of applications around the world
  • Solutions used in: Pollution & Air Quality Monitoring; Exhaust Gas Analysis; Process Control Applications
