Description
Bently Nevada 3300/16‑13‑01‑00‑00‑00‑00
- Technical & Performance Parameters:
- Channel quantity: 2 independent measuring channels
- Input transducer: 3300 series eddy‑current proximity probe system
- Measuring range: Determined by ordering option 13
- Frequency response: 4 Hz‑4000 Hz
- Per‑channel configurable high‑pass / low‑pass filter
- Operating temperature: ‑40 °C ~ +70 °C
- Power supply: Supplied via 3300 rack backplane
- Material Composition: Metal front panel with multi‑LED status indication; multilayer industrial PCB integrating signal demodulation circuit, filter circuit, threshold comparison and alarm‑drive circuit; metal locking latch for rack installation.
- Structural Characteristics: Single‑width plug‑in module for 3300 rack chassis. Front panel shows channel OK, alert and danger alarm status via LED lamps. Rear edge connector connects rack backplane power, dual‑channel probe signal input, alarm bus and analog output. Supports hot‑swap inside rack.
- Working Principle: Processes gap‑voltage signal output by eddy‑current proximity probes. Demodulates to obtain shaft radial vibration peak‑to‑peak value. Filters signal according to set frequency parameters. Compares real‑time vibration value with programmed alarm thresholds. Drives alarm relay output when thresholds are exceeded. Provides analog output of vibration value for external recording and monitoring system.
- Application Scenarios: Radial vibration monitoring for large steam turbines, centrifugal compressors, generators in power and petrochemical industries. Realizes fault early warning and machinery trip protection for rotor unbalance, misalignment and shaft rub‑impact. Applies to projects requiring specific ordering option settings.
- Installation Requirements: Install in standard 3300 rack slot. Complete two‑channel proximity probe wiring. Confirm jumper configuration matches ordering option 13 requirement. Adjust probe working gap voltage during commissioning. Signal wiring must keep distance from high‑voltage and high‑current cables. Guarantee rack cabinet ventilation and heat dissipation.
- Usage Notes: Retain original jumper configuration record before module replacement. Verify probe gap voltage and measurement reading correctness during commissioning. Latched alarms need manual reset after fault elimination. Do not operate beyond specified environmental range. Regularly check cable integrity and front‑panel indicator state.
