Description
Bently 3500/20‑01‑02‑00 (125768‑01)
- Key Features: High‑speed multi‑channel synchronous transient‑data capture; Keyphasor‑synchronized sampling trigger; external termination mode; outputs waveform, orbit and 1X‑vector rotor‑dynamic data; compatible with all 3500 series monitor modules; hot‑swap maintainability.
- Technical Specifications & Performance Parameters
- Power consumption: 8.3 W typical
- Operating temperature: 0 ℃ ~ +60 ℃
- Storage temperature: ‑40 ℃ ~ +85 ℃
- Data sampling rate: high‑synchronous multi‑channel sampling
- Weight: 0.51 kg
- Agency approval: base version without hazardous‑area certification
- Material Composition: FR‑4 high‑performance multilayer printed circuit board; high‑speed FPGA signal‑processing chip; precision timing circuit components; gold‑plated backplane edge connector; metal front‑panel with multi‑color LED indicators; external termination‑matching circuit components.
- Structural Features: Full‑height plug‑in rack‑module structure; front‑panel LED indicators for power, bus and transient‑data status; rear‑side gold‑plated edge connector connects to rack backplane bus; external‑termination signal wiring connects to separate matching I/O module; mechanical locking latch fixes module inside rack slot.
- Working Principle: Module receives Keyphasor trigger pulse and multi‑channel raw measurement data via rack backplane bus. It executes synchronous high‑speed sampling for vibration waveform, rotor orbit and amplitude‑phase vector data. Buffered high‑resolution transient diagnostic data transmits to external diagnostic instruments through external termination I/O module.
- Application Scenarios: Rotor dynamic analysis for large‑scale steam turbines and centrifugal compressors; fault‑event transient waveform capture; connection with third‑party dynamic‑vibration analysis instruments; petrochemical complex 3500 machinery‑protection rack diagnostic data output.
- Installation Requirements: Insert module into dedicated full‑height rack slot; lock mechanical latch firmly; install corresponding external‑termination I/O module; configure transient‑data‑acquisition parameters inside 3500 rack configuration software; finish external signal wiring on I/O module; verify data transmission to diagnostic host.
- Usage Notes: Forbid hot‑swap without following official maintenance procedure; strictly implement static‑electricity protection during module installation and handling; inspect front‑panel LED working status in daily inspection work; preserve rack configuration backup file; check I/O module wiring tightness during overhaul cycles.
