PROCESS WEIGHING AND MEASUREMENT
Thayer provides essential process tools
Thayer Scale is the pioneering developer of continuous weighing and feeding equipment for the dry solids conveying and processing industries. Our equipment provides that rare combination of precision measurement and extreme reliability in a wide variety of industries and markets.a paragraph.
Thayer Scale’s proprietary Force Measurement Suspension System (FMSS) is an interposed active structure, consisting of one or more articulated members, placed between the load receptor (hopper, platform, weigh suspension, etc.) and a load cell. FMSS functions as a force filter; it discriminates between net load measurement forces and all other undesirable extraneous forces. In standard weighing systems, load cells often interpret vibration as weight variation. FMSS technology makes load cells virtually immune to the detrimental effects of vibration.text and replace it with your own fresh content.
We employ FMSS in the following designs:
Constant sensitivity platforms (flexure and cable scales)
Graded sensitivity weighbridges (conveyor belt scales)
Lateral torque transmitting devices (Model D)
1) Adjustable mechanical tare balancing of dead loads (typically as high as 200 times net loads) to maximize measurement signal
Reduces signal transmission problems
Enhances zero temperature stability
Reduces susceptibility to moisture migration
Lessens dependency on high-quality terminal connections
Sums all load forces to one load cell, simplifying troubleshooting and reducing costs
2) Significantly-reduced load receptor deflection
Desensitizes belt tension effects (conveyer belts and weigh scales)
Desensitizes inlet/outlet flexible connections and weigh loops wiring (loss-in-weight feeders)
3) Reduced zero-shifting as a result of foundation distortion
Substantial zero-shifts can occur if a structure’s supporting frame yields under load or settles over time. Loss-in-weight feeders and belt scales mounted to conveyor stringers are particularly sensitive to foundation distortion.
4) Accessibility for load cell inspection or removal
Leaves load cell undisturbed during inspections
Expedites realignment and removal, reducing downtime
5) Simplified test weight application for calibration
Provides remote tracking and reporting of weight storage and application
A test weight calibration is always part of the FMSS system. (A resistor calibration is never used on Thayer scales.)
6) Lower signal velocity and acceleration under dynamic conditions
Enables accurate conveyor weighing at speeds in excess of 1,000 feet per minute on conveyor belt scales
Thayer Scale’s conveyor belt scales & conveyor weighing systems are designed for a range of accuracies: high accuracy loading and unloading systems, custody transfer and NTEP-approved versions (0.10% – 0.125%), inventory control and processing needs (0.25% – 0.5%), and various stone and aggregate applications (0.5% to 1%). Customers in fertilizer, mining, ore, copper, and coal industries utilize our conveyor belt scales in severe applications and in some of the harshest manufacturing environments. Other industries, including pulp and paper and tobacco processing, use our belt scales for light-loading applications. These examples illustrate how our standard designs can support a wide range of belt scale applications with only minor modifications.
We offer many special configurations with our conveyor weighting system and scale prices; designed for light-scale loading of materials such as biomass, wood chips, saw dust, tobacco and MSW. We build 1, 2, 3, 4, 6 and 8 idler belt scales supporting belts from 14 to 96 (and over) inches wide.
