Heat Flux Sensors / Micro-Foil®

MICRO-FOIL® HEAT FLUX SENSORS

27036, 20457, 27132, 27133, 27134, 27160, 27170, 27270

Effective with all methods of heat transfer, including radiation, convection, and conduction.
Exclusive full range of sizes from 1206 surface component size to large area arrays.
Linear millivolt output gives the heat transfer rate.
Easily attached to any flat or curved surface and completely non-invasive.
Dual function models measure both heat transfer and surface temperature.
Low cost models with interchangeable output for commercial applications. (i.e. Model 27160 with large area sensor arrays)
Operating temperature range from –300°F (–184°C) to 500°F (260°C).

For precise measurement of heat transfer (loss or gain) through any material surface.
