Description
Bently 3500/45‑01‑00 (135137‑01)
- Key Features: Four independent measurement‑input channels; multi‑type‑transducer compatibility supporting proximity‑probe, AC‑LVDT, DC‑LVDT and rotary‑position‑transducers; configurable measurement‑mode including thrust‑position, differential‑expansion, case‑expansion and valve‑position; channels configurable in‑pair mode; per‑channel adjustable Alert and Danger alarm‑setpoints; hot‑swap maintainability; front‑panel multi‑color LED status indicators.
- Technical Specifications & Performance Parameters
- Input channel quantity: 4 independent channels
- Typical power consumption: 7.8 W
- Operating temperature: 0 ℃ ~ +60 ℃
- Storage temperature: ‑40 ℃ ~ +85 ℃
- Weight: 0.49 kg
- Material Composition: FR‑4 high‑Tg multilayer printed circuit board; industrial‑grade signal‑conditioning and analog‑digital‑conversion chips; gold‑plated back‑plane edge connector; metal front‑panel equipped with multi‑color LED status indicators; metal shielding‑can for analog‑signal circuits; mechanical‑locking‑latch assembly.
- Structural Features: Full‑height plug‑in rack‑module mechanical‑structure; front‑panel LED indicators for power‑supply, channel‑signal‑health and alarm‑state; rear‑side gold‑plated edge‑connector mates with 3500 rack‑back‑plane bus; field‑transducer wiring terminates on matched I/O termination‑module; mechanical latch fastens module securely inside rack‑slot.
- Working Principle: Module generates required excitation‑signal for connected transducer type. Transducer feedback‑signal enters module and passes through analog‑signal‑conditioning circuit. Analog‑to‑digital converter converts conditioned signal into digital measured‑position value. Real‑time measured‑value compares with user‑programmed Alert and Danger alarm‑thresholds. Alarm‑status flags transmit to rack‑back‑plane bus for relay‑output modules and communication‑gateway modules.
- Application Scenarios: Thrust‑bearing axial‑position monitoring for steam‑turbine and centrifugal‑compressor units; rotor differential‑expansion measurement for large turbomachinery; turbine case‑expansion monitoring; control‑valve position feedback monitoring; petrochemical‑and‑power‑plant 3500‑series TSI machinery‑protection racks.
- Installation Requirements: Insert full‑height position‑monitor module into designated rack‑slot; lock mechanical‑latch completely; install matched I/O termination‑module and complete field‑transducer wiring; select transducer‑type and configure measurement‑mode, alarm‑thresholds and transducer‑system total‑length‑parameter inside rack‑configuration‑software; perform gap‑calibration commissioning and verify position‑reading correctness.
- Usage Notes: Implement ESD static‑protection measures during module‑handling; strictly follow official maintenance‑procedure for hot‑swap‑operation; do not mismatch configured transducer‑system total‑length‑parameter with actual field‑wiring length; inspect front‑panel LED‑status during daily‑inspection rounds; back‑up rack‑configuration‑file after completing parameter‑modification operations.
