Product Description

The Bently Nevada 330400-01-05 is a high-precision industrial piezoelectric accelerometer designed for casing vibration and high-frequency machinery condition monitoring applications. As a core surface-mounted vibration sensing unit for the Bently Nevada 3500 machinery protection system, it specializes in measuring casing acceleration, high-frequency vibration and gear mesh vibration of rotating and reciprocating equipment. It converts mechanical vibration acceleration into standard linear electrical output signals, providing accurate high-frequency vibration data for mechanical fault diagnosis, equipment condition trending and safety protection judgment, effectively capturing early defects such as component wear, gear abnormality and structural resonance.

Adopting shear-type ceramic piezoelectric crystal sensing architecture and integrated charge amplifier design, this accelerometer features fixed 100 mV/g high sensitivity and 50 g peak measurement range, fully complying with API 670 industrial machinery monitoring standards. It supports a wide frequency response range from 10 Hz to 15 kHz, perfectly covering high-frequency vibration characteristic signals of gears, bearings and structural components that cannot be detected by conventional displacement probes. The three-wire integrated structure simplifies field wiring while ensuring stable signal transmission. With all-stainless steel fully sealed rugged housing, it features excellent corrosion resistance, dustproof and waterproof performance, adapting to high-temperature, oily and humid harsh industrial environments. Built-in anti-interference shielding structure suppresses on-site electromagnetic noise and signal drift. With ultra-wide temperature adaptability and certified hazardous area compliance, it supports 24/7 uninterrupted high-frequency vibration monitoring for critical industrial rotating machinery systems.
