Grain Silo Level Indication Solution: Economical High Level Sensing in Grain Storage Bins
Keep the cost low, but reliably detect the high level of
grain in forty-five (45) storage bins. The lowest cost level indicator
/ sensor for this type of application is typically a Tilt Switch.
In this application all bins are filled with a “broadcaster” device
that facilitates the gentle handling of the grain to ensure individual
As a result of using a device that
fills the bins very gently and slowly, the level in the bin increases
This reduction in fill rate can prove problematic with tilt type
switches as it may be possible to gradually engulf the switch rather
than “tilt” it to activate the switch output. The surface
area of the tilt switch had to be increased if it was to be activated
by the material and tilted to an angle of 17 degrees that would
activate it. Making a larger size tilt switch would not be economical.
Monitor recommended an attachment to its TC-3 tilt switch. This
attachment was an “actuator” that consisted of an
8” diameter ball float attached from the bottom of the tilt
switch with a short section of pipe. This proved to be the solution
and also economical and reliable. Monitor can equip its tilt switches
with ball float actuators to meet the application.
