The HF01 high temperature heat flux sensor is intended for high intensity heat flux and surface temperature measurement. The HF01 sensing technology can also be adapted for other high intensity heat flux/temperature measurement applications on request.


The HF01 is intended for energy balance studies within industrial furnaces, boilers, fluidized beds, distillation columns and ovens. The sensing element of the HF01 is incorporated in a rugged stainless steel housing. A metal sheathed cable conduit extends 3 feet (900 mm) from the stainless sensor housing, providing high temperature protection for the sensor signal cable. Both sensor and metal signal cable conduit are designed to withstand temperatures up to 800 degrees C. The extension cable leading from the metal cable conduit is insulated in Teflon. To avoid the possibility of any current leakage, a silicone sleeve is installed over the metal sheathed cable conduit section. The HF01 outputs both heat flux (microvolt analog signal) and temperature signal data (type K thermocouple). The thermocouple allows for accurate measurement of both sensor surface contact and sensor housing temperature.
