The guidelines for calibrating industrial piezoelectric accelerometers are dependent upon the sensing element utilized in each sensors. For quartz sensors, the calibration value is guaranteed to remain stable for a minimum of 5 years, when used within the published operating guidelines for these sensors. Sensors with ceramic sensing elements should be calibrated at least once a year. Piezoelectric ceramics are typically pre-aged to maximize stability but are still subject to sensitivity degradation over time. All sensors should be recalibrated after any suspected physical damage due to excessive mechanical shock, extreme thermal transients, excessive temperatures, or other extreme environmental influences. 

In calibrating industrial piezoelectric accelerometers, IMI offers two standards of calibration. ICS-1 calibration supplies a detailed calibration certificate, which is illustrated below, in compliance with ISO 10012-1, and is traceable to the N.I.S.T.(National Institute of Standards & Technology). ICS-2 calibration provides a low cost option for calibrating industrial sensors which do not require a full range calibration due to their application. This standard provides a single point calibration value, which is traceable to the N.I.S.T., and is laser etched on the sensor's case for easy reference. These services are available on all of our industrial accelerometers as well as any of our competitors' models.
