BENTLY NEVADA 3500/61 133811-02 Temperature Monitoring Module
1. Product Description The BENTLY NEVADA 3500/61 133811-02 is a six-channel temperature monitoring module designed for industrial machinery health management. As part of the BENTLY 3500 Series, it supports both Resistance Temperature Detector (RTD) and Thermocouple (TC) inputs, enabling precise temperature measurements in critical rotating equipment such as turbines, compressors, and pumps. The module integrates with the 3500 Rack Configuration Software for configurable alarm thresholds, trending, and data logging. Its dual-channel redundancy and advanced signal conditioning ensure reliable performance in harsh environments, aligning with API 670 and ISO 10816 standards.

3. Advantages and Features
Multi-Channel Flexibility: Simultaneously monitor up to six temperature points with mixed RTD/TC inputs.
ISO/API Compliance: Direct support for ISO 10816 vibration severity and API 670 safety system requirements.
Predictive Maintenance: Real-time trending and alarm thresholds reduce unplanned downtime.
Rack Integration: Hot-swappable design allows module replacement without system shutdown.
4. Application Areas and Use Cases Industry Applications:
Power Generation: Steam turbine bearing temperatures.
Oil & Gas: Pump motor windings and compressor seals.
Manufacturing: Extruder barrel temperature control.
Case Study: A chemical plant reduced maintenance costs by 20% using the 3500/61 to monitor reactor jacket temperatures. Early detection of thermal runaway via configurable alarms prevented equipment damage.
5. Competitor Comparison
Mixed Input Support: Unique ability to handle both RTD and TC inputs on the same module, unlike competitors requiring separate units.
Software Integration: Native compatibility with BENTLY’s 3500 Series software for unified data management.
Space Efficiency: Six channels in a single module reduces rack space compared to multi-module alternatives.

6. Selection Recommendations
Sensor Type: Choose RTD for stable, long-term measurements or TC for rapid temperature changes.
Isolation Needs: Opt for the TC isolated version in high-voltage environments.
Redundancy: Use triple modular redundancy (TMR) for safety-critical applications requiring zero downtime.
7. Precautions
Sensor Installation: Ensure proper grounding and shielded cables to avoid EMI.
Calibration: Verify sensor accuracy annually using BENTLY’s 3500/05 Calibration Interface.
Power Management: Maintain stable AC supply to prevent voltage fluctuations affecting measurements.
