Description
Bently 3500/72M | Part Number:140471‑01
Technical Specifications:
- Signal Channel Quantity:4 channels
- Compatible Main Module: 3500/72M rod‑position monitor
- Supported Transducer: Bently 3300‑series eddy‑current probe system
- Operating Temperature:0°C ~ +60°C
- Storage Temperature:‑40°C ~ +85°C
- Installation Position: Rear side of 3500/72M main monitor module Functional Features:
- Internal termination for four‑channel eddy‑current probe signal input
- Provides reliable signal connection between field transducer cable and main monitor circuit
- Integrated circuit protection components for transient‑voltage suppression
- No external termination block required, simplifies cabinet wiring layout Application Scenarios:
- Matched with 3500/72M main module for reciprocating compressor rod‑drop monitoring in oil‑gas, petrochemical industry Material Composition:
- Circuit Substrate: FR‑4 fire‑retardant printed circuit board
- Signal Terminal: Gold‑plated screw‑type signal terminals
- Connector: Gold‑plated inter‑board connector for connecting to 3500/72M main module Structural Characteristics:
- Rear‑mounted plug‑in I/O sub‑assembly for 3500/72M main monitor module
- Four groups of screw terminals for field proximity probe cable connection
- Inter‑board connector mates directly with main module circuit board Working Principle: Field eddy‑current probe signal cables connect to screw terminals on 140471‑01 assembly. This assembly routes transducer signals through inter‑board connector to main 3500/72M monitor module circuit board for signal conditioning and measurement processing. Built‑in transient‑suppression components absorb surge interference from field cable side. Installation Requirements:
- Insert 140471‑01 I/O assembly to rear side of 3500/72M main monitor module before installing whole module into rack
- Power‑off rack power supply during installation operation
- Tighten field cable terminal screws with specified torque value
- Use matched Bently Nevada proximity probe and extension cable Usage Notes:
- Do not apply over‑voltage to signal terminals
- Inspect terminal screw tightness periodically under vibration environment
- Prevent dust and moisture invading assembly
