Wood-Mizer
Dehumidification Dry Kiln System
measures and regulates internal kiln conditions
through the use of Dry Bulb and Wet Bulb Sensor
Technology. Each of these sensors measure different
temperatures inside the kiln chamber and regulate
various system functions. They provide information
about the kilns internal conditions used to
determine relative humidity (RH) and estimated
moisture content (EMC). The two sensors are
installed within the kiln chamber and are connected
to the kilns controller where the information they
collect can be managed and utilized by the kiln
operator, and stored for later reference.
This sensor measures the dry bulb temperature
(DBT). The DBT measurement given by the sensor is
the true thermodynamic temperature inside the kiln.
You can set the desired DBT from the kiln controller.
This setting will control the kilns exhaust vents
and heat, which will be automatically adjusted to
accommodate the desired DBT.
Example: If the DBT falls below the set parameter
the system will turn on the heat. Or if the DBT rises
above the set parameter then the system will open
the vents.
If your DBT is rapidly fluctuating a thermal lag may
be added to the sensor to help stabilize readings,
contact
Wood-Mizer
for information on how to
install one if necessary.
This sensor measures the wet bulb temperature
(WBT). The sensor equip with a water wick will
be cooled through evaporation bringing its
temperature reading below that of the dry bulb.
This lower temperature is the WBT, it is the lowest
temperature that can be reached inside of the kiln,
through the evaporation of water, under the current
ambient conditions. You can set the desired WBT
from the
kiln controller as well. This setting controls the
kiln compressor and spray system which will be
automatically adjusted to accommodate the desired
WBT.
Example: If the WBT falls below the set parameter
the system will turn on the spray system. Or if the
WBT rises above the set parameter the system will
turn on the compressor.
