Thin foil flexible radiant flux sensors consist of a thermoelectric panel laminated between flexible heterogeneous plastic layers with shiny reflectors on one or their both external sides.
Size 30x30mm + connexions PTFE wires 1m
The Model GHT-1C Geothermal Heat Flow Transducer measures directly, local heat fluxes in the earth.
The flow of heat to, or from a surface on which the transducer is placed creates a small temperature difference between the upper and lower surfaces of the transducer.
