The Thayer cable suspension system (Patented) utilizes a
series of stainless steel cables in conjunction with Torque
Transfer Tubes to accurately focus force to a tension type
load sensor. Force measurement is decoupled from load position
and mass counterbalanced to accurately measure net material
weight.
Design
principle:
The sum of the torques generated by each pair of corner
cables is proportional to scale loading. Torque A is added
to Torque B via Torque Tube#1. The sum of these is added
to Torque C via the torque transfer cable and equalizing
levers. This sum is then added to Torque D via torque Tube#2.
The weight on the load sensor extension lever is selected
and positioned to oppose that portion of the summed torques
attributable to tare. The remaining torque value is proportional
to net loading and is opposed by the load sensor.
Features:
• Accurately measures
load regardless of load position.
• Immune to support structure
deflections and process vibrations.
• Feeder may be frequently
moved without scale damage or re-calibration.
• Inherently self aligning
to gravity.
• Nulls out heavy tare
loads.
• Scale may be suspended
from above or supported from below.
