Ultra sensitive industrial heat flux sensor
IHF03 ultra sensitive industrial heat flux sensor measures heat flux and temperature, typically in industrial high-temperature environments. The instrument’s stainless steel housing is very robust and mitigates pressure differences through a micro breather. IHF03 is 25 times more sensitive than model IHF01, making it suitable for use at relatively low heat flux levels. IHF03 complies with industrial safety standard CE and is particularly suitable for trend-monitoring and comparative testing. IHF03 is not suitable for use in wet or humid environments or environments with exposure to aggressive chemicals.

25 times more sensitive
than IHF01
IHF03 measures heat flux and surface temperature of industrial equipment like furnaces, boilers, fluidized beds, distillation columns and ovens. The sensors inside IHF03, a thermopile and a type K thermocouple, are protected by a stainless steel body. It is suitable for long-term use at one location as well as surveys at multiple locations. IHF03 measures heat flux through the object on which it is mounted, in W/m², as well as the temperature in °C. An optional magnet frame is offered for easy mounting on magnetic surfaces.
IHF03 is 25 times more sensitive than model IHF01, so that, with the same measurement accuracy of its output voltage, it can be used to measure much lower heat flux levels. When equipped with the optional magnet frame and optional black coating, IHF03 replaces model IHF02 high temperature heat flux sensor.
The part of the cabling closest to the sensor is a special high-temperature metal sheathed cable with an interlocked spiral stainless steel armour. The sensor as well as the high-temperature cable and armour withstand temperatures up to 850 °C. The temperature range is reduced to 650 °C in case the optional black coating is used. The magnet frame can be used up to 500 °C. The low-temperature extension cable has a jacket of PVC type plastic. Small laser-drilled holes mitigate high internal air pressure at high temperatures.
IHF03 advantages
- high sensitivity
- robust
- suitable for use at high temperatures
- signal wires electrically insulated from the sensor body
Suggested use
Trend-monitoring and comparative measurement of heat flux and surface temperature in industrial installations, such as the shell of aluminium reduction cells.
IHF03 operation
Using IHF03 is easy. It can be connected directly to commonly used data logging systems. The heat flux, in W/m², is calculated by dividing the IHF03 output, a small voltage, by the sensitivity. The sensitivity is provided with IHF03 on its product certificate. The temperature sensor is a conventional type K thermocouple. Equipped with heavy-duty cabling and a fully stainless-steel casing, IHF03 has proven to be very reliable. It survives long-term installation under dry conditions. IHF03 should not be exposed to direct water splashes, condensing water, rain and environments with aggressive chemicals.
