Figure-of Merit Z of thermoelectric sensor
= N × α × Rt
Z=
U – sensor signal at heat flux Pe;
N – number of pellet pairs inside a sensor;
RT – thermal resistance;
α – Seebeck coefficient (average value P-N pair)
(N × α)2 × Rt
ACR
Calibration expression with use of Z, ACR and
Seebeck coefficient α

(α × N)
Se = Sa × S
× Z × ACR
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.
