Airstream and Temperature Control Plant
The
Mechanical Setup
An inner aluminium tube including an heating element as well as
an axial fan with a regulating flap is mounted on top of an acrylic
base plate.
A differential pressure transmitter, a PT100 temperature sensor with
transmitter as well as an electrical connector box are mounted at the
base plate.
