Heat flux sensor system for use in aluminium smelter / furnaces

Back to overview

The ALUSYS has been designed for use in the study of aluminium smelters / furnaces. The system consists of a Measurement Control Unit and a number of heat flux / surface temperature sensors of type HF01 with magnet frame. These sensors can be mounted on the steel shell of the smelter.


ALUSYS system is used to perform measurement of heat fluxes and surface temperature at high temperatures. It is designed in particular for the study of aluminium smelters / furnaces. The electronics can accept 12 or 3 sensors (using a multiplexer, depending on the model).The assembled data are exported to a PC via USB. A PC, not part of the system, can be used for on-line graphical monitoring as well as data collection. The system can operate for a limited time on a battery that is incorporated in the system box (at least 24 hours). For all information on the HF01 sensors, the user should read brochure and manual for that sensor.

Advantages of HF01 relative to competing models are:

  • robust, in particular at high temperatures
  • fast response time, so reduced experiment time
  • low thermal resistance; improved measurement accuracy
  • one sensor model suitable for measurements on the shell as well as in the powder material

Reference users of HF01 are Comalco, Alcan, Corus and Norsk Hydro. See some of our references.
