Self-Calibration Method

Measurement Scheme

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).

Sensitivity of thermoelectric heat ﬂux sensor Sa [V/W]

Figure-of Merit Z of thermoelectric sensor

Sa =

= N × α × Rt

Z =

(N × α)2 × Rt

ACR

Sa =

× Z × ACR

(α × N)

Se = Sa × S

where S - surface area

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.
