Product Description
BENTLY 135613-01-00 is a high-performance temperature monitoring module within Bently Nevada’s 3500 Series condition monitoring system, specialized in real-time temperature measurement of critical rotating machinery components (bearings, gearboxes, stator windings). As an essential component for thermal fault detection, BENTLY 135613-01-00 supports multiple temperature sensor types (RTDs, thermocouples) and features high-precision signal conversion, enabling accurate temperature readings with ±0.1°C resolution. Unlike generic temperature modules, BENTLY 135613-01-00 is factory-calibrated to integrate seamlessly with 3500 Series racks and Bently’s System 1 software, providing thermal trend analysis and over-temperature alarm capabilities [Product Link: Please supplement], where you can access the module’s sensor compatibility list and calibration datasheet. In practical deployments, BENTLY 135613-01-00 is paired with PT100 RTDs for turbine bearing temperature monitoring and Type K thermocouples for compressor discharge housing temperature tracking, working alongside vibration modules to deliver comprehensive machinery health data. Additionally, BENTLY 135613-01-00 includes built-in sensor fault diagnostics (open/short circuit detection) and hot-swappable functionality, ensuring uninterrupted temperature monitoring even during module maintenance.

Advantages and Features
- Multi-Sensor Compatibility: BENTLY 135613-01-00 supports both RTDs and thermocouples across multiple types, eliminating the need for separate modules for different temperature measurement requirements and reducing system complexity.
- High-Precision Measurement: ±0.1°C accuracy for RTDs and advanced cold junction compensation for thermocouples ensure reliable temperature data, critical for detecting early-stage overheating in bearings or windings.
- Comprehensive Diagnostics: Built-in detection of sensor open/short circuits and drift alerts enable proactive maintenance of temperature sensing systems, preventing false alarms or missed fault conditions.
- Hot-Swappable Design: Compatible with 3500 rack hot-swapping, BENTLY 135613-01-00 can be replaced without powering down the system, minimizing downtime for critical machinery monitoring.
- Seamless System Integration: Optimized for Bently’s System 1 software, the module supports real-time data logging, thermal trend analysis, and automated over-temperature alarms, streamlining predictive maintenance workflows.
- Hazardous Area Compliance: ATEX/IECEx certification allows installation in Zone 1 explosive environments (refineries, chemical plants), meeting strict safety standards for high-risk industrial settings.
Application Fields and Cases
Core Application Fields
- Power Industry: Turbine generator stator winding temperature monitoring, boiler feed pump bearing temperature detection
- Petroleum and Chemical Industry: Refinery reactor temperature tracking, compressor discharge manifold temperature measurement
- Metallurgical Industry: Blast furnace hot blast stove temperature monitoring, rolling mill gearbox temperature sensing
- Marine Engineering: Ship main engine cylinder head temperature monitoring, offshore platform gas turbine exhaust temperature measurement
Typical Application Case
In a 600MW combined-cycle power plant’s gas turbine monitoring project, the plant deployed BENTLY 135613-01-00 modules to monitor 16 critical temperature points (bearings, turbine casing, generator windings) using PT100 RTDs and Type K thermocouples. BENTLY 135613-01-00’s high-precision RTD measurements detected a 2°C increase in the No. 2 turbine bearing temperature over a 48-hour period—an early sign of lubrication degradation. The module triggered an over-temperature alarm, prompting maintenance teams to inspect and replenish the bearing lubricant during a scheduled outage, avoiding a potential bearing seizure that could have caused $500,000 in damage and 72 hours of downtime. BENTLY 135613-01-00’s 8-channel design also reduced the number of modules required by 50% compared to 4-channel alternatives, simplifying rack wiring and lowering installation costs [Product Link: Please supplement] (see the project’s temperature trend data and maintenance cost analysis).

Selection Suggestions
- Sensor Type Needs: Prioritize BENTLY 135613-01-00 for mixed RTD/thermocouple deployments; choose Allen-Bradley 1756-TC16 if only thermocouples are used with Rockwell PLCs.
- Accuracy Requirements: Select BENTLY 135613-01-00 for critical machinery (turbines, compressors) requiring ±0.1°C RTD accuracy; lower-precision applications may use cost-effective alternatives.
- Environment Matching: Use ATEX-certified BENTLY 135613-01-00 in Zone 1 hazardous areas; standard versions are suitable for non-explosive industrial environments.
- System Compatibility: Ensure compatibility with Bently 3500 Series racks and existing temperature sensors (confirm RTD/thermocouple type and wiring configuration).
- Scalability Planning: Each BENTLY 135613-01-00 supports 8 channels—calculate module quantity based on total temperature monitoring points (e.g., 2 modules for 10-16 points).
Precautions
- Wire RTDs using 3-wire or 4-wire configurations (per Bently guidelines) to eliminate lead resistance errors, especially for long cable runs to BENTLY 135613-01-00.
- Calibrate thermocouple cold junction compensation annually using Bently’s certified calibration tools to maintain measurement accuracy across temperature ranges.
- Configure over-temperature alarm thresholds based on machinery OEM specifications (e.g., turbine bearing max temperature = 120°C) to avoid unnecessary shutdowns or missed faults.
- Test sensor fault diagnostics after installation by simulating an open circuit (disconnect a sensor wire) to verify that BENTLY 135613-01-00 triggers the correct alarm and logs the fault.
- Perform hot-swapping only when the 3500 rack’s redundant power supply is active; wear an anti-static wristband to prevent electrostatic discharge damage to the module’s circuitry.
- Store spare modules in anti-static packaging in a dry, temperature-controlled environment (-20°C ~ 50°C) to prevent moisture or extreme temperatures from degrading components.
