Pre-Calibration Essentials

Always start with a clean workspace and calibrated tools. Check your multimeter accuracy (±0.5%). Inspect sensor cables for damage. Power down equipment first – safety is critical. Pro tip: Use thermal imaging to find hidden connector issues.

Calibration Procedure

  1. Mount the 31000 sensor on a vibration calibrator
  2. Set baseline frequency (60Hz) using BN 3701 calibrator
  3. Adjust output to factory specs (200mV/g ±5%)
  4. Test at 3+ amplitude points for linearity
  5. Validate with spectrum analysis software

Important: Allow 30-minute warm-up. Skipping this causes 3-7% reading drift.

Maintenance Best Practices

  • Quarterly: Clean probes with isopropyl alcohol
  • Bi-annually: Re-torque mounts to 20 Nm
  • Annually: Replace oxidation-prone connectors
  • Always: Log humidity (>80% skews readings)

Field trick: Apply dielectric grease to O-rings. Extends seal life 18+ months.

Accuracy Validation

  • Parallel test with new sensor
  • Compare against historical baselines
  • Impact test with rubber mallet

Acceptable variance: <±2%. Higher? Check grounding.

Why This Matters

Proper calibration catches early failures. In 2023, a client avoided $220k turbine damage by finding 0.3g imbalance during routine checks. Consistent maintenance cuts failures by 67%.
