Hi Pals,
What about a cooled active dip stick for pile top sensing. I am
currently experimenting with a heavy plate, or rod, raised and lowered
on a chain with a float level sensor in between. When the plate rests on
the chips the chain slackens and drops the sensor plunger through the
sensor float shutting or breaking a contact. As the chips drop the plate
falls pulling the sensor through the float. Although I am using this in
an open top affair, is could be possible to slide it through a seal. If
that gums up then drive it off a hinged arm. Chiptec has for a long time
used a hinged arm which passively rides the pile up and down opening and
closing a switch. That works for under or side fed chips. For chips
falling from above it could be coupled to a drop plate and an small
gear-motor to constantly probe the gasifier like a rescuer searching
for survivors after an avalanche.
Did I paint a coherent picture?
