Product Details:

The EV27A series sensor is a new type of speed sensor based on the piezoelectric acceleration sensor that has been professionally designed with high precision and embedded with a precision integrating circuit. The internal structure adopts advanced isolation shear structure,which has a wide frequency response range and stable and reliable technical performance. Compared with the traditional magnetoelectric type,due to the use of piezoelectric crystals as sensitive elements,there are no moving parts inside,no degradation and wear will occur,and 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.

main application:

Vibration monitoring of bearing housings,housings or structures;
Health monitoring of water pumps,motors,fans and other equipment;
Long-term vibration monitoring of power generation equipment;
Used for industrial online monitoring and field environment monitoring.
