4.3 Heat Flux Interface
The SP-016 provides heat flux measurements in W/m2. Heat Flux sensors, such as the OMEGA HFS-05, consist of a
thermopile device and a temperature compensation (TempCo) measuring device, typically a T type thermocouple.
For OMEGA HFS products, the heat flux is calculated as:
q” = Vq” / S@ToC
Where q” is the heat flux, Vq” is the measured voltage (in mV) and S@ToC is the temperature compensated sensor sensitivity,
calculated as:
S@ToC = (TempCoGain * ToC + TempCoOffset) * SCalib
ToC is the measured temperature from the T type thermocouple. From the HFS-05 datasheet:

5.1.6 Heat Flux User Calibration Parameters
The SP-016 provides a single User Calibration register that may be set while the device is in the User Calibrate mode
and is ‘added’ to the calculated value during normal operation, providing a fixed offset to the calculated Heat Flux
value. During the User Calibration process, the actual (independently measured) Heat Flux value (Target Value) may be
entered and the SP-016 will save the difference between the current measured value and the Target Value as the
Calibration value. The User Calibration may be used when the sensor is measuring 0 heat flux to provide a simple
method to correct for minor offset errors.
Note: The device must be put into the ‘Calibration’ mode to access the User Calibration parameters.

5.2.5 Thermocouple User Calibration Parameter
The SP-016 provides a Thermocouple User Calibration register that may be set while the device is in the User Calibrate
mode and that is used to adjust the Cold Junction Compensation (CJC) value during normal operation.
During the User Calibration process, the actual (independently measured) Temperature value (Target Value) may be
entered and the SP-016 will the difference between the current measured temperature and the Target temperature to
adjust the CJC value. The User Calibration may be used when the thermocouple is measuring 0 degrees (Ice Point
calibration) to provide a simple method to correct for minor offset errors.
Note:The device must be put into the ‘Calibration’ mode to access the User Calibration parameters.
