Sensing surface
HRD Heat Flux Sensor has two flat sides. The sensing (working) side is completely black. Bottom side contains
two terminal pads for SMT soldering process and a mark between them.

N – number of pellet pairs inside a sensor;
RT – thermal resistance;
α – Seebeck coefficient (average value P-N pair)

where S - surface area
Measurement Scheme
Self-calibration to be made by measurement of Figure-of-Merit and ACR Resistance of thermoelectric heat flux
sensor by four-wire method which is provided by four wires of the FET cable connected to the sensor.
Use series of Z-Meters made by RMT for
measurement of Figure-of-Merit and ACR
resistance of thermoelectric heat flux sensor.
Or RMT Datalogger DX8140 developed for
HTX, HFX series of heat flux sensors.
