Damage to push-pull force gauge sensors primarily results from overload, impact, and environmental factors. Preventive measures include:
1、Strictly limiting usage within 120% of rated load capacity;
2、Installing buffer devices to absorb impact loads;
3、Maintaining ambient temperature between -10°C to 50°C; 4) Performing weekly zero-point calibration.
Repair methods follow a graded approach:
Level 1 damage (signal drift <5% FS): Restorable using professional calibration equipment;
Level 2 damage (linearity deviation >3%): Requires strain gauge component replacement;
Level 3 damage (structural deformation): Mandates complete sensor unit replacement.
Critical note: Post-repair sensors must undergo three full-scale cycle tests and ISO 376 standard verification to ensure measurement accuracy within ±0.1% FS. Comprehensive inspection every 2,000 measurements can reduce sensor failure rates by 80%.
