Description
Compact charge‑mode accelerometer optimized for single‑axis dynamic measurements where space and high/low temperature performance are critical. The ceramic shear design provides stable mechanical behavior across the specified temperature range. Typical applications include laboratory dynamic testing, component qualification, high‑temperature vibration monitoring and embedded measurements where adhesive mounting is required.
