Application > Examples of application
1.1.10 IC 40, staged control with
online adjustment of the burner
capacity
For processes that require a
homogeneous temperature distribution
and high temperature accuracy in
the furnace.
If only a low heat output is required,
for example to maintain the
temperature in the furnace, the
burner can continue to run in
intermittent mode. The adjustment
angle of the valve is reduced by the
analogue input (4 – 20 mA) of the
actuator and the burner capacity is
therefore lowered. This ensures
uniform temperature distribution even
with a low burner capacity.
This function of the actuator IC 40 can
also be used in the ceramics industry
to correct the lambda value or for
temperature compensation purposes
in hot-air applications.
