Model 27160 Heat Flux Sensor from RdF Corporation

The RdF Model 27160 Heat Flux Sensor is a differential thermopile. Heat passing through a calibrated polyimide membrane produces a small temperature differential (see thermal impedance feature). The signal is proportional to the difference in temperature and the number of junctions in the thermopiles.


  • Low thermal impedance
  • High sensitivity
  • Fast response
  • Wide temperature range
  • Thin and flexible

Applications Include

  • HVAC
  • Medical
  • Structural Analysis
  • Equipment Analysis
  • Safety

RdF’s new low cost planar heat flux sensor self-generates an interchangeable, linear mV measurement of heat flux in or out by all modes: convection, conduction or radiation. Output polarity defines the direction of the net total heat flux measured at up to 150°C. Exclusive features include the interchangeable mV output and a conformable, sealed configuration for lamination or surface mounted application. Edge connections can be soldered. Adhesive backing and addressable wide area sensor arrays are available. Temperature control can be enhanced by reacting to heat flux changes detected before temperature can change. Building controls systems can add real time reaction to solar and wind loads.

RdF’s Micro-Foil® Heat Flux Sensors feature true isothermal properties. Thermal losses are kept to a minimum and highly accurate readings are obtainable because of their extremely thin construction (Low thermal impedance). The mV or mV output is proportional to the heat flux passing through the sensor thickness. Their sensitivity is controlled by the thickness of the thermal barrier and the number of thermocouple junctions within the sensor.
