Weighbridge Inspection Logger
Truck scale checks — deck, load cells, T-junctions, approaches, drainage, test results and seal status; offline log for site operators.
New weighbridge inspection
Daily zero checks by operators; monthly walkdowns; calibration/stamping per legal metrology schedule (annual typical).
Field guide: Weighbridge Inspection Logger
A weighbridge sells numbers — every defect is money moving in someone's direction at up to 100+ tonnes a transaction. The physics findings are mundane and expensive: stones wedged in the side gaps bind the deck (the classic cause of drifting zeros), mud builds under the deck until it shoulders part of the load, an approach slab settles and every truck weighs light by its tilt. This logger pairs the operator-level checks (zero, repeatability with a known truck, corner tests) with the housekeeping that determines whether those checks stay passed.
The legal-metrology panel tracks what regulators actually enforce — verification stamps in date, seals intact (a broken seal voids trade use in most jurisdictions, full stop) — and the fraud-watch panel records the human findings: partial-on-deck weighments, manual-override frequency, the event-log anomalies that audits ask about after disputes. Dated logs per scale are the operator's defense and the auditor's shortcut.
Field tips
- Walk the side gaps with a flashlight weekly — one stone in the gap explains a week of 'electronics problems'.
- Run the same loaded truck across twice at month-start; repeatability beyond a division is mechanical binding until proven otherwise.
- Check under-deck clearance after every storm and material spill; buildup grounds the deck so gradually nobody sees the day it started.

Frequently asked questions
What does a corner test reveal?+
Placing the same test load over each load cell in turn exposes individual cell or mounting problems — a corner reading differently means that cell's calibration, mount or wiring diverged. It localizes faults that whole-deck tests average away, which is why monthly walkdowns include it where test weights permit.
Why does debris in gaps matter so much?+
The deck must float freely on its cells; anything bridging deck to foundation — stones in side gaps, mud underneath, closed expansion gaps, mis-set bump stops — carries force around the cells. Symptoms: unstable zero, poor return-to-zero, weather-correlated drift. It's the diagnosis behind most 'calibration won't hold' complaints.
What happens when a verification seal is broken?+
In most legal-metrology regimes the scale immediately loses trade-use status — transactions on it are unenforceable/illegal until re-verification. Cell replacements, indicator repairs and even some software changes break seals by design. 'Seal broken' findings stop trade weighing first, schedule the verifier second.
What operational patterns suggest weighment fraud?+
Trucks straddling with rear axles off-deck, repeat 'errors' favoring one party, manual overrides clustering on certain operators/shifts, event logs with gaps, and disputes correlating with specific vehicles. Controls: full-on-deck CCTV verification, override audit trails, and exactly the dated observation log this tool maintains.
