Quick Detail

Description

The 330400-02-CN Accelerometer is a high-precision industrial-grade piezoelectric vibration sensor meticulously engineered by Bently Nevada for critical machinery condition monitoring in the world's most demanding environments. Designed as a superior acceleration measurement solution, this compact and robust transducer is purpose-built for capturing high-frequency vibration data directly from machine casings, enabling advanced predictive maintenance and asset protection strategies across sectors like oil & gas, power generation, and heavy manufacturing. Featuring an integral M8 X 1 stud for secure mounting and a compact overall case length of 40 mm, the 330400-02-CN offers versatile and reliable installation on a wide array of rotating equipment, from pumps and compressors to turbines and gearboxes.

This Bently Nevada accelerometer delivers exceptional measurement performance with a standard sensitivity of 100 mV/g (10.2 mV/m/s²), providing a strong, high-resolution signal ideal for detecting subtle high-frequency fault signatures. Its wide acceleration range of up to 50 g peak ensures that the sensor can accurately capture both normal operational vibrations and transient high-energy events without signal saturation. A key strength of the 330400-02-CN lies in its exceptional frequency response, capable of faithfully measuring vibrations from as low as 10 Hz up to 15 kHz. This broad bandwidth is critical for identifying incipient failures in rolling element bearings and gear mesh components, where defects generate characteristic high-frequency energy long before they impact overall machine health.

Applications

This accelerometer is expertly applied for high-frequency gearbox monitoring, where its broadband frequency response (10 Hz to 15 kHz) is essential for capturing gear mesh frequencies and associated sidebands. Its 100 mV/g sensitivity provides the necessary resolution to detect early-stage faults like tooth pitting, spalling, or misalignment, enabling maintenance teams to schedule repairs before these issues lead to catastrophic gear failure and extended production stoppages.

The sensor is a critical component for rolling element bearing condition monitoring on motors, fans, and pumps. It excels at detecting the high-frequency shock pulses and resonance ringing generated by initial bearing defects such as raceway spalling or rolling element cracks. The low broadband noise floor of 0.004 g rms allows it to identify these subtle signatures, supporting advanced diagnostic techniques like envelope demodulation for early and accurate bearing fault diagnosis.

Certified with CSA, ATEX, and IECEx approvals, the 330400-02-CN is ideally deployed for general machinery vibration monitoring in hazardous areas, such as gas compressor stations, refinery process pumps, and offshore platforms. Its robust construction and wide operating temperature range ensure reliable, continuous operation in these challenging environments, providing essential vibration data for protecting critical assets within classified explosive atmospheres.

Specifications

Competitive Advantage

1.Optimized for High-Fidelity, High-Frequency Diagnostics

The 330400-02-CN Accelerometer offers a distinct advantage with its excellent high-frequency response up to 15 kHz and a very low broadband noise floor (0.004 g rms). This combination provides an exceptionally clean and precise signal, which is paramount for early fault detection in critical components like bearings and gears. It captures subtle defect signatures that are often lost in the noise of standard industrial accelerometers, enabling more accurate and earlier diagnostic insights.

2.Ruggedized Design with Global Hazardous Area Compliance

Built to withstand harsh industrial environments, this sensor features a durable hermetic seal and an extensive operating temperature range (-50°C to +130°C). Its Multiple Agency Approvals (CSA, ATEX, IECEx) deliver a significant competitive edge by providing a single, globally compliant solution for hazardous location monitoring. This eliminates the complexity and cost of sourcing different sensors for different regional safety standards, streamlining global operations and inventory management.

3.Reliable Performance with Robust Signal Headroom

Engineered with a substantial acceleration range of 50 g peak and excellent amplitude linearity (±1%), this accelerometer provides ample signal headroom to accurately measure both steady-state vibrations and unexpected high-energy transients without clipping or distortion. This reliability ensures trustworthy data is always available for protection and analysis, reducing the risk of missed alarms or false readings during upset conditions, which contributes to a lower total cost of ownership.
