Description
Bently Nevada 3300/16‑01‑02‑01‑00‑00‑00
- Technical & Performance Parameters:
- Channel quantity: 2 independent measuring channels
- Supported transducer: 3300 series 5 mm / 8 mm eddy‑current proximity probe system
- Measuring range: 0‑80 mil peak‑to‑peak
- Frequency response: 4 Hz‑4000 Hz
- Filter: Independent high‑pass / low‑pass filter per channel
- Operating temperature: ‑40 °C ~ +70 °C
- Power supply: Powered by 3300 rack backplane
- Material Composition: Anodized aluminum front panel with multi‑LED status indicators; high‑precision multilayer PCB with gap‑voltage demodulation circuit, filter network, threshold comparison circuit and alarm drive components; metal latch for rack fixation.
- Structural Characteristics: Single‑width plug‑in module for 3300 rack chassis. Front‑panel LED indicates channel OK status, alert alarm, danger alarm. Rear golden‑plated edge connector connects rack backplane, two‑channel probe input, alarm bus and analog output. Hot‑swap supported within rack.
- Working Principle: Receives gap‑voltage signal from eddy‑current proximity probes installed towards rotating shaft. Demodulates signal to get shaft radial vibration peak‑to‑peak value. Passes signal through user‑configured filter network. Compares measured vibration value with alert and danger thresholds. Activates corresponding alarm relay when exceeding thresholds. Converts vibration value to analog output signal for external DCS or recorder.
- Application Scenarios: Radial shaft‑vibration monitoring for steam turbine, gas turbine, centrifugal compressor, turbo‑generator. Used for rotor unbalance, shaft misalignment, shaft rub‑impact fault detection and machinery protection trip. Mainly applied in power plant, refinery and chemical‑plant critical rotating equipment.
- Installation Requirements: Insert into standard 3300 rack slot. Complete two‑channel proximity‑probe system wiring. Set measuring‑range jumpers and filter parameters according to machine parameters. Adjust probe working gap voltage during commissioning. Signal cables must be separated from high‑power cables to avoid EMI. Ensure rack cabinet has sufficient cooling air flow.
- Usage Notes: Check probe gap voltage during commissioning phase. Set filter parameters matching equipment rotating frequency. Latched alarms must be manually reset after fault removal. Do not operate beyond rated temperature range. Regularly inspect cable condition and front‑panel LED status.
