Some of our customers put our heat flux sensors to the test. For them, we do the impossible. Example: this reinforced fluxmeter used in a combustion chamber, whose pressure quickly goes from 100 bar to vacuum. Observe the side micro-screw: it provides additional support to the ceramic insulating ring (in white). Goldsmith's work, right?

Ready to be subjected to the fires of hell ! Six heat flux sensors (IHF series) have been delivered to CNES (French Space Agency) for the inaugural Ariane 6 flight (FM1). They will equip the launch pad in different locations, so as to estimate the thermal stress of the structure during the European launcher ignition and elevation. Many thanks to CNES for trusting our technology. Designed for a total heat flux of 10 MW/m², four of these sensors are in standard version (M16 thread). Two others are tailor-made, with an elongated body. These special probes are intented to be placed on the Vulcain2 deflector.

Discover our new miniaturized heat flux sensor configuration from the IHF series! From left to right :convective, radiative and total versions. Intended for glued mounting, this arrangement is very compact (less than 20mm high).

Supported by the Poc in Labs (University of Paris-Saclay) innovation and entrepreneurship initiative, our project is now completed, with the successful delivery of the first exemplar of our Data Acquisition field case. Our device allows accurate heat flux measurement in the most hostile environments, such as outdoor experiments, industrial processes,... but also when sedentary DAQ are missing or lacking performance. In brief : 8 thermocouple channels + 8 BNC channels (voltage/resistance), 20 kHz sampling rate per channel, external trigger, Li-ion battery allowing 10 hours continuous measurement, ... Warm congrats to #arcale for their incredible work.

NexTherm Sensing is proud to announce the release of our Dynamic Heat Flux (DHF) sensor range, which allows the measurement of transient phenomena with a response time between 1 microsecond and 1 millisecond. You will see on the picture below one of our sensors after an exposure to a fireball at 2500°C. Still perfectly functional, but a bit dirty! More seriously, in response to the demands of experts in detonation and pyrotechnics, we have initiated and completed the development of a "surface thermocouple" type sensor, with the ability to also measure a thermal flux. By this achievement, NexTherm Sensing is continuing to expand its measurement offer in extreme environments, always in the spirit of custom-made.

We wanted to show you how our CHF (cooled) heat flux sensor works when subjected to a 1200°C flame : 400kW/m² :) In this configuration, the CHF sensor is used in combination to a Lauda Loop100® for the sensor cooling.Heat transfer fluid is simply water, with a set temperature fixed at 20°C. Measurement is carried out using the very smart PicoLog® USB device.

For one of our customers, leader in the fields of industrial risk assessment, our DHF sensor has been improved to reach very low response time, well below the 1 millisecond of its big brother (the standard DHF-10 model). With its optimized architecture and a robust sensitive thin film, our "surface temperature" sensor is THE alternative to traditionnal micro #thermocouples, thanks to its unrivalled compromise between sensitivity and reactivity.

Here are two specimens of our latest batch of IHF heat flux sensors for a specific implementation for one of our aerospace customers. Designed for direct exposure in engine combustion chambers, our sensors are rated for heat flows up to 4MW/m² for 30 seconds.
