Information

Overview Manuals Common Applications Product Precautions
The 3500/65 145988-02 is a high-performance 16-channel temperature monitoring module. It is specifically designed for online condition monitoring of rotating machinery and is widely used in industrial automation and critical equipment protection systems.
    • High-Density 16-Channel Monitoring
    • Universal Sensor Compatibility (RTD & TC)
    • TMR Capability for Plant Safety
The Bently Nevada 3500/65 monitor provides 16 channels of temperature monitoring and accepts both resistance temperature detector (RTD) and isolated tip thermocouple (TC) temperature inputs. The monitor conditions these inputs and compares them against user-programmable alarm setpoints. The monitor is programmed using the 3500 Rack Configuration Software. You can configure the 16-Channel Temperature Monitor to accept isolated tip thermocouples, 3-wire RTD, 4-wire RTD, or a combination of TC and RTD inputs. In Triple Modular Redundant (TMR) configurations, you must install temperature monitors in groups of 3 adjacent monitors. In this configuration the monitor uses 2 types of voting to ensure accurate operation and to avoid single point failures.

Thermal Power
Monitors steam turbine bearing temperatures and generator stator windings to prevent catastrophic thermal breakdown.

Petrochemical & Refining
Keeps continuous track of process gas compressor and pump motor temperatures operating in highly hazardous, volatile zones.

Oil & Gas
Safeguards large gas turbine-driven or motor-driven pumping stations along cross-country pipelines from overheating.

Hydroelectric Power
Controls and protects large, low-speed vertical hydro-generator thrust bearings and stator cores.

Iron & Steel
Monitors blast furnace blower fans and heavy rolling mill motor drive systems exposed to extreme ambient heat.

Chemical Processing
Ensures continuous operation of critical process fans, agitators, and high-pressure chemical synthesis reactor pumps.

 When using this module, it is critical to strictly match the rear I/O module and cables, and never hot-swap under power to prevent chip damage. Since the module supports both RTD and TC inputs, you must accurately configure sensor types and alarm thresholds via software before commissioning. Additionally, maintain proper rack ventilation and grounding, and regularly check for zero-drift to ensure precise signal acquisition and overall system safety.
