Acoustic sensitivity is another critical factor for piezoelectric transducers as most vibration measurements are conducted in environments with high sound pressure levels, which can interfere with the accuracy of results.
Unless your piezoelectric accelerometer is completely sealed, it can succumb to changes in low-frequency responses due to moisture ingress in humid environments. These are merely a select few of the environmental effects that can dramatically impact the performance of your accelerometer.
Every Brüel & Kjaer piezoelectric accelerometer comes with a comprehensive list of specifications regarding their sensitivity to specific environmental phenomena. The methods of measuring these effects are described in international standards ISO 5347 (Methods for the Calibration of Shock and Vibration Pickups) and the American standard ANSI S2.11-1969 (The Selection of Calibrations and Tests for Electrical Transducers Used for Measuring Shock and Vibration).
We can guarantee optimum accelerometer performance with reliable operation at very high levels of vibration and no limit on the temperature range imposed by the mounting. Interested in learning more? Contact a member of the Brüel & Kjaer sales team today.
