BENTLY 3500/44-01-00
Product Introduction
BENTLY 3500/44-01-00 is a 4-channel displacement monitor designed for the 3500 Machinery Protection System. It receives inputs from proximity sensors and processes them into measurable vibration and position parameters.
This module compares processed signals against user-programmable alarm setpoints. Channels are configured in pairs to execute functions like radial vibration, thrust position, differential expansion, eccentricity, and REBAM.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: We check source traceability and verify serial numbers against anti-counterfeit databases. Visual inspection confirms no physical damage or connector corrosion.
- Live Functional Test: Power-on self-checks validate basic operation. We run continuous load tests exceeding 24 hours with temperature logging to ensure stability.
- Electrical Parameter Test: Insulation resistance is verified using a 500 V Megger, requiring >10 MΩ. Ground continuity is also strictly checked.
- Firmware Verification: We read and record internal firmware versions. DIP switch and jumper settings are photographed for future reference.
- Final QC & Packaging: The unit is sealed in an anti-static bag. A QC Passed label with the inspection date is applied before shipping.

Replacement Pitfall Guide
❗ Channel Pairing Requirement: Channels must be configured in pairs. Channels 1 and 2 execute one function, while channels 3 and 4 execute another. You cannot configure all four channels independently.
❗ Sensor Compatibility: This module supports specific Proximitor types including 3300, 7200, and 3000 series. Non-standard transducers require scale factors between 85 and 230 mV/mil.
❗ Zero Position Adjustment: When replacing sensors, use the configuration software’s zero position utility. This requires an active connection to the 3500 rack for real-time feedback.
❗ OK Limits Verification: For non-standard sensors, ensure at least 2 V exists between upper and lower OK limits. Incorrect limits cause false alarms during startup.
❗ ESD Damage: Use an anti-static mat during installation. Dry environments significantly increase electrostatic discharge risks to sensitive electronics.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
- 3500/44-01-00 → 3500/40M : Needs Adaptation — Displacement Monitor vs. General Proximitor Monitor
- 3500/44-01-00 → 3500/45 : Needs Adaptation — Displacement vs. Position Monitor (Valve, Shell Expansion)
- 3500/44-01-00 → 3500/42M : Incompatible — Displacement vs. Proximitor/Seismic Dual Input
- Scan Cycle: < 1 ms (simulated load, 4 I/O points)
- Comms Throughput: Backplane interface (Modbus TCP via 3500/22M TDI)
