The sensing (working) side is completely black. Bottom side contains two terminal pads for SMT soldering process and a mark between them. Self-Calibration Method Sensitivity of thermoelectric heat flux sensor Sa [V/W] Sa = U P 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 Sa = 1 (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. 46 Warshavskoe shosse. Moscow 115230 Russia, ph: +7-499-678-2082, fax: +7-499-678-2083, web: www.rmtltd.ru Copyright 2015.
