ALUSYS is a measuring system for trend-monitoring and mobile survey of heat flux and surface temperature in industrial environments. Sensors and electronics have the robustness necessary for this application. Powered from a low-voltage rechargeable battery, it is easy and safe to use. In its standard configuration the system consists of an MCU Measurement Control Unit in a metal housing and 12 x heat flux and surface temperature sensors of model HF01. Measured data are stored for later analysis.
ALUSYS measures heat fluxes and surface temperatures in demanding environments. It is designed for industrial surveys, for example surveys of aluminium smelters / furnaces. The ALUSYS system employs dedicated sensors and electronics. Their high accuracy and sensitivity ensure that ALUSYS will still measure under circumstances where competing systems no longer perform reliable measurements; i.e. down to very low heat fluxes. The measurement and control unit, MCU, has a robust aluminium housing and accepts 12, or optionally 3, sensors. The system generates a measurement file, including a time-stamp, heat flux and temperature for all sensors. The measurement data are stored in the MCU and are later downloaded to a PC. The user is responsible for data analysis. A PC or the Keyboard Display may be used for real time measurement review and control of the data storage.
Powered and charged using a low voltage, ALUSYS is safe to use. The system can operate for a limited time on MCU’s internal rechargeable battery. For all information on the HF01 heat flux and surface temperature sensors, see the HF01 manual. Optionally other sensor models may be used.
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
Suggested use• Surveys of industrial installations, for example of aluminium melting furnaces
