1. Product Introduction: Bently Nevada 3500/60 133835‑01

The 3500/60 133835‑01 is a module in the 3500 Machinery Protection System dedicated to temperature monitoring. It is intended to interface with temperature sensors such as RTDs or thermocouples, converting sensor signals into digitized, conditioned data that integrates directly into the broader vibration, displacement, and protection network.

By embedding thermal data within the same rack and system as mechanical health parameters, this module enables more sophisticated diagnostics and more robust protection schemes. It is especially useful for early detection of overheating, abnormal thermal gradients, or runaway thermal events in critical rotating machinery components.

3. Applications

The 3500/60 133835‑01 module is used in settings where temperature data plays a critical role in maintaining machinery health and preventing failure. Key application scenarios include:

• Monitoring bearing shell and lubricant temperatures in turbines, motors, compressors

• Detecting overheating in gearboxes or bearing housings

• Thermal anomaly detection in pumps, fans, and related rotating equipment

• Correlating temperature changes with vibration or displacement trends for root cause analysis

• Implementing combined alarms when temperature and mechanical variables jointly exceed thresholds

• Integrating process thermal sensors of adjacent equipment into the machine health framework

This module is especially beneficial in power plants, petrochemical facilities, refineries, heavy industry, and environments where both mechanical and thermal behaviors must be observed in tandem.

4. Advantages & Key Features

• Dedicated Temperature Capability: Provides six input channels exclusively for RTDs or thermocouples

• Full Integration: Embeds thermal data within the 3500 system so temperature and mechanical data share the same architecture

• Calibration & Compensation: Supports sensor linearization and internal cold junction compensation for accurate thermocouple readings

• Alarm & Logic Flexibility: Each channel may have customized alert/danger thresholds and logic rules

• Buffered Outputs: Outputs are buffered so external systems can access them without interfering with internal processing

• Compact & Modular Design: Fits into standard 3500 rack, aligning with other protection modules

• Robust in Harsh Environments: Operates within industrial temperature and humidity ranges

• Holistic Diagnostic Context: Enables advanced diagnostics by combining thermal and mechanical metrics
