Used for Calibration
Connector Pins
RMT Heat Flux Sensor Cable is ended by miniature connector FMC 0,5/6-ST-2,54-18211355 (Phoenix).
The reciprocal connector p/n is MCV 0.5/6-G-2.54 SMD R44-1821588 (not included).
Self-Calibration Method
Sensitivity of thermoelectric heat flux sensor Sa [V/W]
U
Sa = = N × α × Rt
P
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)

Se = Sa × S 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.
