How often should an industrial sensor be re-calibrated?
With proper handling and usage, Wilcoxon industrial accelerometers do not need frequent re-calibration. Wilcoxon’s proprietary crystal preparation stabilizes the ceramic crystals used within the sensors to minimize output drift due to aging. Maximum sensitivity drift is less than 1% over the life of the sensor. If exact accuracy of vibration levels is necessary, the sensors should be re-calibrated annually. Otherwise, Wilcoxon sensors need to be re-calibrated only if exposed to mistreatment (overshock, extremely high temperatures) or if required by regulations (ISO 9000, Nuclear Regulatory Commission). Wilcoxon offers calibration and testing services for any make sensor.
