Load Cells, Scales & Weigh Modules
Accurate weighing for every application. From silo and hopper weigh modules to bulk bag frames, mixers, and sanitary washdown solutions, Carolina-MT specifies engineered load cells and controls for GIW and LIW processes.
Weigh modules/load cells support silos, hoppers, bulk bag unloaders, feeders, mixers, and day tanks—commonly for Loss-in-Weight (LIW) feeding. Bench & floor scales support Gain-in-Weight (GIW) drum/pail filling and checkweighing. Indicators provide the readout and control—stand-alone or PLC-integrated for batching.
Weigh Modules & Load Cells
Engineered mounts and load cells designed for silos, hoppers, mixers, and bulk bag systems—available in carbon steel, stainless, and wash-down configurations.
Hopper & Feeder Weigh Modules — RL502 Series
Compact, accurate modules for hoppers and feeders. Ideal for LIW feeders or GIW batching, with self-checking hardware to manage side-loads and thermal movement.
Bulk Bag Weigh Modules — RL1800
Purpose-built for bulk bag unloaders/fillers. High stability with anti-lift features and robust stops to handle side-load moments during bag changeout and operation.
Mixer Weigh Modules — RL9000TWM
Heavy-duty tension modules for mixers/blenders with dynamic loads. Sanitary/wash-down options with hermetic load cells and rugged mounts for repeatable accuracy.
Silo & Tank Weigh Modules — EZ Mount
Compression-style modules for large vessels. Self-checking design with uplift prevention and thermal expansion handling for long-term stability and accuracy.

- Floor: 1,000–10,000+ lb capacity; readability 0.2–1 lb.
- IP-rated load cells and junction boxes for wash-down/industrial duty.
Applications
- Gain-in-Weight filling of drums, pails, and totes.
- Manual batching / kitting stations.
- Receiving, inventory checks, and QC sampling.

Gain-in-Weight (GIW) vs Loss-in-Weight (LIW)
| Approach | How It Works | Best For | Accuracy (typ.) | Notes |
|---|---|---|---|---|
| Gain-in-Weight | Weighs material added into a hopper/scale (weight increases). | Drum/pail filling, weigh hoppers, discrete batches. | ~±0.1–0.25% FS | Simpler mechanics; ideal for fill-to-weight and manual batching. |
| Loss-in-Weight | Weighs feeder/supply as it discharges (weight decreases). | Continuous or semi-continuous dosing/ratio control. | ~±0.1–0.25% FS | Excellent for precise feed rates with fast/dribble cutoff. |

Weighing FAQ
What accuracy can I expect from silo weigh modules?
With proper mounting, calibration, and environmental considerations, ±0.1–0.25% of full scale is typical for process applications. We’ll design to your tolerance and select the right modules and indicators.
Should I choose LIW or GIW for batching?
Use LIW for precise continuous/semi-continuous feeding. GIW is ideal for discrete fills and drum/pail batching. We support both approaches and integrate with PLC/HMI as needed.
Can indicators control the entire batch?
Yes—advanced indicators offer fast/dribble, preact learning, tolerance checks, and data logging; or we can integrate with PLCs via Ethernet/IP, Modbus, or analog I/O.
