Bently Nevada 330425-01-05 | Accelerometer Acceleration Tranducer

Manufacturer: Bently Nevada

Product No.: 330425-01-05

Mounting Thread Option: 0 1 ¼-28 UNF integral stud

Agency Approval Option: Multiple approvals (CSA, ATEX, IECEx)

Key Specifications

Sensitivity: 10.2 mV/m/s² (100 mV/g) ±5%

Acceleration Range: 490 m/s² (50 g) peak overall within the 10 Hz to 15 kHz frequency span.

Note: Vibration at frequencies above 15 kHz may reduce this range significantly.

Amplitude Linearity: ±1% to 490 m/s² (50 g) peak.

Broadband Noise Floor (10 Hz to 15 kHz): 0.039 m/s² (0.004 g) rms.

Frequency Response: 10 Hz to 15 kHz (600 cpm to 900,000 cpm) ±3dB; 30 Hz to 10 kHz (1800 cpm to 600,000 cpm) ±10%

Performance Characteristics

Temperature Sensitivity: -11% to +3% typical over the operating temperature range.

Transverse Sensitivity: Less than 5% of axial.

Mounted Resonant Frequency: Greater than 30 kHz.

Amplitude of Resonant Peak: 20 dB maximum.

Base Strain Sensitivity

For serial numbers preceded by the letter “G”: 49 mm/s²/mstrain (0.005 g/mstrain)

For serial numbers NOT preceded by the letter “G” (shipped prior to April 2004):
980 mm/s²/mstrain (0.100 g/mstrain) without Mounting Base;,
4.9 mm/s²/mstrain (0.0005 g/mstrain) with Mounting Base supplied with the accelerometer.

Bently Nevada recommends installing with the Mounting Base to minimize base strain sensitivity for units NOT preceded by “G”.
