Quick Detail

Description

The 330425-02-CN Accelerometer is a high-performance piezoelectric vibration sensor engineered by Bently Nevada, specifically designed to deliver precise, reliable measurements of high-amplitude casing vibration in the most demanding industrial environments. As a flagship member of the Bently Nevada accelerometer product line, this model is tailored for critical machinery applications where standard sensors are prone to signal saturation, offering an enhanced performance envelope that outperforms conventional vibration monitoring solutions. Unlike generic accelerometers with limited dynamic range, the 330425-02-CN Accelerometer boasts a peak acceleration range of 75 g and a calibrated sensitivity of 25 mV/g, making it the definitive choice for capturing high-energy vibration events such as gear mesh frequencies, aerodynamic instability in high-speed compressors, and rolling element bearing faults in heavy-duty rotating equipment.

This 330425-02-CN Accelerometer is built with optimized mechanical parameters to ensure seamless integration and long-term durability: it features an M8 X 1 integral stud mounting thread that provides a rigid mechanical coupling to machinery casings, critical for accurately transmitting high-frequency vibration data up to 15 kHz without signal loss or resonance damping. With an unthreaded length of 0 mm, an overall case length of 50 mm, and a compact total cable length of 0.3 meters (12 inches), the accelerometer is ideal for space-constrained installations where short-distance wiring to monitoring systems is required. Its compact dimensions of 2.3x2.1x6.2cm and lightweight profile of only 0.08kg further enhance its versatility, allowing for easy mounting on tight machinery surfaces without adding excess weight or requiring extensive modification. Notably, the 330425-02-CN Accelerometer holds multiple global agency approvals including CSA, ATEX, and IECEx, ensuring compliance with safety standards for use in hazardous and non-hazardous industrial zones across the world.

Applications

The 330425-02-CN Accelerometer is extensively applied in heavy-duty industrial gearbox monitoring, where it captures high-frequency gear mesh vibrations and detects early-stage defects such as gear tooth pitting, cracking, or misalignment in drive trains used in cooling towers, cement mills, and conveyor systems. Its 75 g peak acceleration range and 25 mV/g sensitivity prevent signal clipping during high-energy vibration events, while the M8 X 1 integral stud ensures rigid mechanical coupling to gearbox casings for accurate data transmission.

This accelerometer is ideally suited for rolling element bearing (REB) diagnostics in high-speed compressors, turbines, and electric motors, where it monitors ultrasonic stress waves generated by bearing fatigue, lubrication failure, or raceway damage. Its wide frequency span of 10 Hz to 15 kHz captures both fundamental rotational vibrations and high-frequency bearing resonant frequencies, providing critical data for spectral analysis and predictive maintenance strategies in petrochemical and power generation facilities.

The 330425-02-CN Accelerometer serves as a key component for monitoring reciprocating machinery such as reciprocating compressors and internal combustion engines, where it detects mechanical looseness, valve impacts, and piston slap events. Its 5,000 g peak shock survivability and hermetically sealed 316L stainless steel housing withstand the intense mechanical shocks and corrosive environments typical of these applications, while its multiple agency approvals enable safe deployment in hazardous zones where flammable gases or vapors are present.

Specifications

Competitive Advantage

1.Extreme Shock Survivability and Corrosion Resistance

The 330425-02-CN Accelerometer is built with a hermetically sealed 316L stainless steel housing and boasts a 5,000 g peak shock survivability rating, far exceeding the durability of standard industrial accelerometers. This rugged construction ensures the sensor can withstand the intense mechanical impacts of reciprocating machinery and corrosive industrial environments, reducing maintenance frequency and extending service life compared to generic sensors that fail prematurely in harsh conditions.

2.Global Hazardous Area Certification for Versatile Deployment

A standout competitive edge of the 330425-02-CN Accelerometer is its CSA, ATEX, and IECEx approvals, which enable safe use in virtually all global hazardous and non-hazardous industrial zones. Unlike regionally certified sensors that require multinational plants to source multiple variants, this model streamlines procurement processes, reduces inventory costs, and ensures consistent compliance with local safety regulations across international facilities.

3.Integral M8 X 1 Stud for High-Frequency Signal Integrity

Equipped with an M8 X 1 integral mounting stud, the 330425-02-CN Accelerometer provides a rigid mechanical coupling to machinery casings that eliminates resonance damping and signal loss at high frequencies up to 15 kHz. Unlike sensors that rely on separate mounting adapters, this integrated design ensures that the sensor captures an exact representation of casing vibration, delivering the high-fidelity data needed for advanced diagnostic techniques such as enveloping and spectral analysis.
