Force Measurement Suspension System for Weigh Belts
Unique technology provides isolation from all force vectors except material weight.
- A load sensor cannot distinguish between the "meaningful" force of material weight and other forces. THAYER Weigh Feeders are engineered to isolate the load sensor from these other forces for highly accurate material weighing.
- Weight sensing system is totally enclosed and requires no maintenance.
- Weight sensing system has infinite over-load protection (mechanical stops) and weight sensor (LVDT) cannot be damaged by
shock loads.
- Weight signal represents only material load; the dead load (belt & idler) is completely mass counter-balanced.
- Excessive belt tension forces are eliminated by our head pulley drive and low deflection
scale. Friction is defeated by using precision rollers instead of slider decks. Torsional
forces, caused by off center loading and side forces, are decoupled from the true force
transmission by our weigh scale.
Load Cell Utilization Factor >80%
Because THAYER manufactures the load cell, we can provide a load cell with a capacity
that is closely matched to the actual maximum material weight. The tare weight of
the weigh idler and belt are mass counterbalanced. We design our scales such that
the maximum material weight is always > 80% of scale capacity. This results in the
best possible signal resolution. This flexibility is not possible with strain gauge load
cells, which tend to be available in standard capacities of 10, 50, 100, 200, 500 lb.,
etc. Thayer's rugged load cell design assures reliable operation for the life of the weigh
belt. Because our load cells never fail, they are not a recommended spare part. Unique
technology provides isolation from all force vectors except material weight.
Force vector isolation is a Thayer Scale technological advantage. It is one of the best
reasons to buy from the weigh feeder experts at Thayer Scale.
