Model SI Insertion Weigh Belt
Thayer Scale’s Model SI insertion weigh feeder fits into an existing production process to provide real-time continuous flow rate measurement and control.
Thayer Scale’s Model SI sanitary insertion weigh belt feeder is a unique feeder that has been designed to easily fit into an existing production process. The Model SI consists of a short conveyor directly coupled to a mass counterbalanced weight sensing system.
With sanitary stainless-steel construction and a wide range of new belt options and widths (from 18” to 48”), Thayer Scale’s Model SI can be used in many food processes not previously suitable for standard weigh belt feeders.
This configuration permits the use of belts not suitable for conventional weigh belt service, such as wire mesh, modular, cleated, profiled, and other high-tension belts, without compromising measurement accuracy.
The Thayer Scale Model SI comes in either scale over or scale under design. A short support framework and a V-Guided conveyor (12, 18, 24 and 36 wide) makes this the only practical weighing module for insertion into a transition space between existing conveyors or equipment.
Industry Applications
Suitable for hygienic food applications.
- Snack Foods (RTE Cereal, Popcorn, Pretzel Twists, Gummies, Nuts)
- Pet & Animal Feed (Pet Food, Kibble/Bits, Fish Meal)
- Fruits & Vegetables (IQF Fruits and Vegetables, Dehydrated Vegetables)
- Grains & Pasta (Pasta, Cooked Rice)

Core Technologies
⚖️ FMSS™ Force Measurement Suspension System
The scale provides for complete mass counterbalancing of the dead load of the conveyor assembly, permitting the load sensor to react only to the net material load.
⚖️Thayer Instrumentation
The Model SI ships standard with one of Thayer Scale’s range of instrumentation packages enabling the system to operate as either a process stream integrator or as a process controller.
🌀 Flexible Drive Systems
The unique design of the Thayer SI feeder allows for a wide range of drive and belt configurations not normally suited to weigh belt feeders (positive drive, wire mesh, modular, cleated, profiled or other high-tension belts)
📏 Tail Pulley Mounted Speed Encoder
Measures the true speed of the belt via rotation of the idling pulley, belt slippage or breakage is immediately detected because the idling pulley stops rotating.
📐 Customizable Engineered Options
Multiple transmission options that utilize commercially available components, two belt cleaner options to remove fines or residue and maintain zero measurement stability.
🔧 Optional Automated Test Weight Positioning System
Automatic test weight positioning mechanically exercises the scale for safe, verifiable calibrations which can be completed automatically from a supervisory control system or manually initiated by an operator.
🛡️Full-Length Adjustable Skirt Boards
Tapered and flared for product containment, preventing spillage and particle jamming.
Key Benefits
