HUKSEFLUX – NF01

The NF01 needle type heat flux and temperature sensor is used to perform continuous measurement of temperature and heat fluxes in furnace walls. It is designed in particular as a tool for monitoring blast furnaces and smelters. The same technology can be used to manufacture heat flux sensors for different applications.

The NF01 has been designed for studies of the energy balance of industrial blast furnaces and smelters. It has been applied successfully in iron furnace safety systems as well as in a smelter for titania slag production. The main component, the actual sensor, is incorporated in a fully stainless steel needle. This sensor can withstand temperatures up to 700 °C, as well as the aggressive chemical environment of a furnace. Optionally the sensor temperature can be extended to 1000 °C. The extension cable is made of PVC. Sensor output consists of a heat flux signal (microvolt analog signal) and type K thermocouple. NF sensors can be manufactured in such a way that they are fully exchangeable, which is easy for servicing. Also the exact depth of insertion is not critical, which saves installation time.
