3-10 Installing the Pickup Probe for Hopper Loaders
Pickup probes are used to empty gaylords or bulk material containers located beside the
processing machine. The Sterling conveying system can use horizontal take-offs or vertical
pickup probes (or a combination of the two) to supply material to the vacuum hoppers.
; For maximum conveying rates, locate the supply container near the vacuum hopper.
; Connect the pickup probe to a vacuum hopper material inlet tube with a minimum amount of
tubing, bends, and flex hose.
; Secure the flex hose at the probe and the material inlet with hose clamps. Be sure to avoid
loops and kinks, and install grounding wire around the outside of flex hose to prevent static
built-up. Make sure you ground both ends of the grounding wire.
; Put the pickup probe in the material supply. The burrowing action of the probe provides a
steady flow of material.
; To vary the convey rate, cover or open the vent holes on the pickup probe as needed with the
inlet tube.
; If your material bridges frequently and triggers No-Convey alarm conditions, you should
consider using a gaylord tilter or tilter/jogger to supply a steady stream of material to your
conveying system.
