Heat flux measurement
Wittich & Visser also offers sensors for heat flux measurement.
Heat flux is the rate of energy transfer through a given surface.
This quantity can be measured using a heat flux sensor.
The measurement of heat flux is of importance to many sciences.
Most common applications are in building physics, where the heat
flow through walls is one of the factors determining the indoor
climate, in agricultural meteorology, where the heat flux into the
soil is a parameter in the study of evaporation of water, and biology
to measure heat flux from humans or animals. The accurate measurement
of heat flux can lead to energy saving in buildings and to more
efficient use of water in irrigated agricultural area's.
A certain heat flux is created by a non equilibrium in temperature.
The necessary energy is transferred either by radiation, conduction
or flow. With a heat flux sensor it is possible to measure conductive
heat transfer. An additional possibility, when using techniques
with heaters, to study the transfer coefficients (typically from
the air to the sensor).
