Hukseflux IHF01 Heat Flux Sensor

IHF01 industrial heat flux sensor measures heat flux and temperature, typically in industrial high-temperature environments. IHF01 is waterproof, withstands high pressures and is extremely robust. With signal wires electrically insulated from the sensor body, it complies with industrial safety standards, such as CE and ATEX for explosive areas. IHF01 is particularly suitable for trend-monitoring and comparative testing. The same technology can be used to manufacture heat flux sensors for different applications.

Suggested use

  • trend-monitoring and comparative measurement of heat flux and surface temperature in industrial installations

IHF01 measures heat flux and surface temperature of industrial equipment

IHF01 measures heat flux and surface temperature of industrial equipment like furnaces, boilers, fluidised beds, distillation columns and ovens. The sensors inside IHF01, a thermopile and a thermocouple, are protected by a fully sealed stainless steel body. It is suitable for long-term use at one location as well as repeated installation when a measuring system is used at multiple locations. IHF01 measures heat flux through the object on which it is mounted, in W/m², as well as the temperature in °C. The sensors in IHF01 are a thermopile and a type K thermocouple. The thermopile measures the local heat flux. The thermocouple measures the absolute temperature of the surface on which IHF01 is mounted, as well as the approximate sensor body temperature. A thermopile and a thermocouple are passive sensors; they do not require power.


Using IHF01 is easy. It can be connected directly to commonly used data logging systems. The heat flux, in W/m², is calculated by dividing the IHF01 output, a small voltage, by the sensitivity. The sensitivity is provided with IHF01 on its product certificate. Equipped with heavy duty cabling, and having a fully stainless steel casing so that moisture does not penetrate the sensor, IHF01 has proven to be very reliable. It survives long-term outdoor installation.
