Product details
Description of DF9300 piezoelectric vibration velocity sensor
The DF9300 piezoelectric vibration velocity sensor is a new type of velocity sensor that is based on a piezoelectric sensing element sensor and embedded with a precision integration circuit. The internal structure adopts advanced isolation shear structure, with a wide frequency response range and stable and reliable technical performance. Compared with traditional magneto electric devices, due to the use of piezoelectric crystals as sensitive elements, there are no moving parts inside, so degradation and wear will not occur. In addition, the frequency response range is wide, the mechanical moving parts are not easily damaged, the dynamic characteristics are excellent, and the anti-interference ability is strong.
