Heat flux sensors in a flexible design

Whether for building management, monitoring of heating furnaces or for scientific purposes - heat flux measurement is indispensable in many areas of analysis. With a single ALMEMO® data logger the heat flow can be measured simultaneously with many other measured variables. The integration into an existing measurement setup also works smoothly with the ALMEMO® system.

In addition to our own products, we recommend the heat flux plates from Hukseflux. These offer you flexibility and robustness at the same time. Thanks to their thin and flexible foil design, the heat flux plates can be easily mounted on curved surfaces such as pipes using standard adhesives while saving space. A connection block for strain relief ensures stability. The encapsulated cover protects against moisture (protection class IP67). We supply your Hukseflux heat flux plates including an intelligent ALMEMO® connector.

Inside the heat flow sensor is a thermopile that measures the temperature difference across the entire foil. A type T thermocouple is also integrated for temperature measurement. The thermopile and thermocouple are both passive sensors and therefore require no power.

Thermal spreaders reduce the dependence on thermal conductivity - the sensitivity of the sensor is completely independent of the environment. The heat flux sensors have a fast response time and can be easily connected to every ALMEMO® data logger.
