What Is a Gravimetric Coal Feeder Load Cell?
A gravimetric coal feeder load cell is a precision force sensor that measures coal weight passing through a gravimetric feeder, converting it into an electrical signal the control system uses to regulate feed rate. Unlike volumetric feeders (which only measure speed), gravimetric systems use load cells to measure actual weight giving far higher accuracy and preventing the fuel wastage, uneven combustion, and downtime caused by feed-rate deviations.
How the Coal Feeder Weighing System Works
Coal Hopper → Feeder → Load Cell Senses Weight → Signal Transmitter → PLC/Controller → Automatic Feed Adjustment → Stable Coal Supply
This closed-loop weighing system keeps fuel delivery precise with minimal manual intervention.

How to Select the Right Load Cell
Consider: maximum load, feeder type, installation space, environmental conditions, required accuracy, output signal compatibility, and PLC/control integration. Not sure which model fits? Our engineers can evaluate your system and recommend the right solution.
Coal Feeder Load Cell Installation
Quick steps: Inspect mounting surface → position load cell per orientation → torque all fasteners → route/protect cable → connect to controller → calibrate before continuous operation.
Coal Feeder Load Cell Calibration
Calibration ensures the measured weight matches the actual load. Perform it at installation, after replacement, after major maintenance, and per your preventive maintenance schedule. Use certified test weights, verify zero balance, and log all readings for consistency.
Coal Feeder Load Cell Maintenance
| Frequency | Check |
|---|---|
| Daily | Physical damage, cable condition |
| Weekly | Mounting bolts, dust buildup, signal stability |
| Monthly | Mounting assembly, calibration check |
| Annually | Full calibration, wear/corrosion inspection |
Routine coal feeder load cell maintenance extends service life and prevents unplanned downtime.
Coal Feeder Load Cell Troubleshooting
| Issue | Likely Cause | Fix |
|---|---|---|
| Unstable readings | Loose mounting, vibration, cable damage | Secure hardware, check shielding/grounding |
| Incorrect measurement | Calibration drift, poor installation | Recalibrate, verify load path |
| No output signal | Broken cable, connector failure | Check continuity, replace faulty parts |
| Measurement drift | Temperature swings, overload, aging | Verify load within rated capacity, recalibrate |
