Product Overview

The Bently Nevada 3500/65 (Part Numbers 145988-02 and 172103-01) provides high-density temperature surveillance within the 3500 Machinery Protection System. This module accepts up to 16 independent temperature inputs from Resistance Temperature Detectors (RTDs) and thermocouples. It continuously compares these inputs against user-programmable alarm setpoints, ensuring immediate detection of bearing overheating, winding hot spots, or process fluid temperature excursions. We supply this set as 100% Brand New and Original, comprising the main monitor and the corresponding I/O module for comprehensive machinery protection.

Engineering Advantages

High-Density Channel Layout: The 3500/65 maximizes rack space by housing 16 channels in a single slot. This allows for massive temperature monitoring arrays in complex turbine trains without requiring additional chassis expansion.
Triple Modular Redundant (TMR) Support: This module enables TMR configurations when installed in groups of three. The system utilizes voting logic to compare data across the modules, eliminating single points of failure and preventing false trips in safety-critical power generation environments.
Universal Sensor Compatibility: The onboard firmware handles multiple RTD types (100 Ω Platinum) and various thermocouple standards (J, K, T, etc.). This flexibility allows engineers to standardize on one module type regardless of the specific sensors installed on the machine.
Advanced Noise Rejection: Internal circuitry filters out industrial electrical noise and electromagnetic interference (EMI) often found near high-voltage motors. This ensures the temperature data remains stable even in harsh electromagnetic environments.
Diagnostic Self-Checking: The module continuously performs self-tests and monitors sensor health. It detects open circuits, short circuits, or out-of-range signals immediately, activating a "Bypass" or "Not OK" status to alert operators before a malfunction occurs.

FAQs

Can I mix RTDs and Thermocouples on the same 3500/65 module?

Yes. The 3500/65 allows you to configure each of the 16 channels independently via the 3500 Rack Configuration Software. You can assign some channels to RTDs and others to Thermocouples as required by your machinery layout.
Does this part number include both the monitor and the I/O module?

The reference to 145988-02 + 172103-01 indicates a complete set. 145988-02 is the main monitor module, while 172103-01 is the rear I/O module where you land the field wiring.
Is this module suitable for SIL3 rated systems?

Yes. When integrated into a properly configured 3500 system with redundant power and the correct firmware, the 3500/65 contributes to a SIL3 compliant machinery protection solution.
What is the condition of the stock?

We guarantee this is 100% Brand New and Original Bently Nevada hardware in factory-sealed packaging. It comes with a full 12-month warranty from the date of shipment.
