AM216

Product Description

The AM216 features extended low-frequency response and is specifically designed for casing vibration monitoring in industrial rotating machinery. The 

sensor employs solid-state piezoelectric elements with built-in integration circuitry, eliminating the need for additional conditioning modules and providing 

direct output of signals proportional to vibration acceleration. These signals can be connected to various industrial monitoring systems for real-time vibration 

data acquisition.

The sensor features a fully sealed stainless steel housing with excellent shock and corrosion resistance, wide frequency response, excellent linearity, low 

transverse sensitivity, wide temperature range and long-term stable operation.

With built-in isolated shielding structure, the sensor effectively suppresses ground loop interference and electromagnetic interference, supports long-distance 

signal transmission and is easy to install. It accurately captures equipment vibration details and effectively reflects unit operating conditions, providing accurate 

and reliable vibration data for equipment fault warning, condition monitoring and safety protection. Widely used for online vibration monitoring of fans, pumps, 

motors, compressors and other rotating machinery.
