Sensor Drift — Why Calibration Matters Over Time
Industrial vibration sensors experience thermal cycling, mechanical shock, and chemical exposure over years of continuous service. These stresses cause calibration drift — a gradual shift in sensitivity and linear range that is invisible without a calibrated test. A EPRO PR6423/002-030+CON021 that has drifted by 10% will still produce a signal. The monitor rack will still display numbers. But those numbers will be wrong, and machinery protection decisions based on wrong numbers are worse than no protection at all.
We verify every EPRO sensor on a live monitor rack with a calibrated target before shipping. The measured scale factor, linearity, and gap voltage are documented in a printed test report. If the numbers do not match the manufacturer specification, we do not ship. Genuine EPRO. Factory-sealed. 48-hour burn-in. 12-month warranty. Ships within 24 hours.
