Atomic Layer Thermopile (ALTP) heat-flux sensors stand out by its unique characteristics with regard to its temporal resolution. They have a linear characteristic over approximately 10 orders of magnitude and cover a frequency range up to 2 MHz.
The sensors were used in several applications and flow environments in the past:
- Internal combustion engines
- Shock tube investigations and ignition studies of fuels / propellants
- Wind tunnel diagnostics (subsonic to hypersonic flow regime, plasma)
- Boundary layer transition studies
- Rotating Detonation Engines
- Surface temperature determination e.g. steel industry
- Heat transfer studies e.g. for gas turbine cooling
The experimental results were published in several international peer-reviewed journals. An overview of all publications and applications can be found here.
ALTP sensors are commercially available and an overview of sensor modules, flow probes, measuring systems, static and dynamic calibration as well as repair and rental service can be found here.
