The 330425-02-05 is a three-wire piezoelectric casing accelerometer, which is part of the Bently Nevada 330400/330425 Accelerometer Acceleration Transducer family. This product operates as a factory hardware component mounted directly on the surface of rotating machinery casings to convert physical acceleration into proportional AC voltage signals, and is used for gear mesh monitoring as well as high-frequency vibration data acquisition and analysis.
Measures vibration up to 75 g peak across 10 Hz to 15 kHz frequencies
Features a hermetically sealed stainless steel housing with multiple hazardous-area approvals
Pairs with 16925 or 16710 interconnect cables for quick system deployment
The configuration of this specific model number includes dedicated physical interface and agency compliance options. The hardware features a standard 3-pin MIL-C-5015 connector terminal and includes an integral M8 × 1 mounting stud (defined by option -02). Additionally, this assembly contains multi-agency hazardous area approvals (defined by option -05), meeting international explosion protection standards such as CSA, ATEX, and IECEx. The sensor runs from a -24 VDC external power supply, incorporates an internal charge amplifier, and pairs with 3-conductor shielded signal interconnect cables to connect to a backend condition monitoring system.

Power Generation Industry
Monitor high-frequency vibration of gas/steam turbines and generator bearing housings to prevent blade damage or rotor unbalance.
Oil & Gas
Used for casing vibration monitoring of centrifugal compressors and large water injection pumps on offshore platforms or onshore oil wells.
Petrochemical & Refining Industry
Utilize its explosion-proof certifications to safely monitor casing vibration of large hydrocracking pumps and fans in hazardous areas.
Metallurgy & Steel Industry
Monitor the vibration of heavy-duty rolling mill gearboxes to detect broken teeth or gear surface fatigue early.
Hydroelectric Power Industry
Installed on the upper/lower guide bearing casings of hydro-generator units to monitor vibrations caused by hydraulic imbalance or cavitation.
Wind Power Industry
Monitor high-frequency vibration of the speed-increasing gearbox and main generator bearings inside the wind turbine nacelle.
During installation, strictly adhere to the specified tightening torque for the M8 × 1 thread, and ensure the mounting surface is flat and clean for accurate high-frequency signal transmission. Due to its "05" multi-national explosion-proof certification, it must be paired with safety barriers or isolators in hazardous areas, and the cable shield must be reliably grounded at a single end to prevent electromagnetic interference. Additionally, avoid extreme cable bending and regularly inspect the external protective conduit to prevent oil contamination and mechanical wear.
