Bently Nevada 330425-01-05 High-Performance Industrial Accelerometer

Bently Nevada 330425-01-05 Key Specifications

• It offers 10.2 mV/m/s² (100 mV/g) sensitivity with ±5% accuracy, delivering responsive and precise vibration detection.
• It supports 490 m/s² (50 g) peak acceleration within a 10 Hz to 15 kHz frequency span (note: frequencies above 15 kHz may reduce range).
• It provides ±1% amplitude linearity up to 490 m/s² (50 g) peak, ensuring consistent measurement across the range.
• It has a 0.039 m/s² (0.004 g) rms broadband noise floor (10 Hz to 15 kHz), ensuring clean signals in low-vibration scenarios.
• It delivers 10 Hz to 15 kHz frequency response (±3 dB) and 30 Hz to 10 kHz (±10%), covering 600 cpm to 900,000 cpm for versatile monitoring.

Performance Characteristics

• It features -11% to +3% temperature sensitivity over the operating range, maintaining stability in temperature fluctuations.
• It has <5% transverse sensitivity (relative to axial), minimizing cross-axis interference for accurate data.
• It achieves >30 kHz mounted resonant frequency, avoiding interference with measurement signals in industrial environments.
• It exhibits 20 dB maximum amplitude of resonant peak, ensuring reliable performance at high frequencies.

Base Strain Sensitivity

• For serial numbers preceded by "G": 49 mm/s²/mstrain (0.005 g/mstrain) base strain sensitivity.
• For serial numbers NOT preceded by "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 supplied Mounting Base (recommended for minimal strain error).

Environmental & Power Specifications

• It supports 305 meters (1000 ft) maximum cable length without signal degradation, enhancing installation flexibility.
• It operates with -24 ± 0.5 Vdc input voltage, 2 mA nominal bias current, and -8.5 ± 0.5 Vdc output bias voltage (case isolated grounding).
• It functions in -55°C to +121°C (-67°F to +250°F) operating/storage temperature range, suitable for extreme conditions.
• It survives 49,050 m/s² (5000 g) peak shock, ensuring durability in high-impact industrial settings.
• It resists 100% condensing humidity (hermetically sealed) and has <2.21 mm/s²/gauss (225 mg/gauss) magnetic field susceptibility, minimizing interference.
• It holds IP 68 rating (dust-tight, watertight) and multiple agency approvals (CSA, ATEX, IECEx) for global industrial use.

Physical & Installation Details

• It weighs 99 g (3.5 oz) without cable, lightweight for easy mounting on machinery without added stress.
• It measures 23 mm (0.93 in) diameter and 59 mm (2.3 in) height (including mounting stud), compact for space-constrained setups.
• It uses a 3-pin MIL-C-5015 receptacle (316L stainless steel) for secure, corrosion-resistant electrical connection.
• It requires 4.1 N·m (3.0 ft·lb) mounting torque to ensure stable attachment and optimal vibration transfer.
• It features 316L stainless steel case material for corrosion resistance and supports any mounting orientation.
