Introduction to the Bently Nevada 330102-00-13-15-02-05 Accelerometer
The Bently Nevada 330102-00-13-15-02-05 is a high-performance, 4-20 mA loop-powered accelerometer used for condition monitoring of industrial machinery. It is part of the Bently Nevada's comprehensive portfolio of vibration sensors designed to provide reliable data for protecting critical assets.
This sensor operates on the piezoelectric principle, where a crystalline material generates an electrical charge proportional to the acceleration it experiences. This sensor has a built-in electronic circuit that converts this charge into a standardized 4-20 mA output signal that is directly proportional to the vibration velocity (e.g., in mm/s or in/s). This loop-powered design makes it simple to integrate with most Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), and other monitoring systems without requiring external signal conditioners in many cases. Its primary purpose is to detect and monitor overall vibration levels to identify developing faults such as unbalance, misalignment, rolling element bearing defects, and resonance.
