3500/65-01-00 Bently Nevada 16-Channel Temperature Monitor
The 3500/65-01-00 is a high-density, 16-channel temperature monitoring module designed for the Bently Nevada 3500 Machinery Protection System. It provides precision conditioning for RTDs and thermocouples, ensuring reliable thermal data for critical plant infrastructure.
Configuration Breakdown
The ordering structure for the 3500/65 series is as follows:
- 3500/65-AA-BB
- AA (I/O Module Type): 01 = RTD/Isolated Tip TC with Internal Terminations.
- BB (Agency Approval): 00 = None (Standard Industrial).
Technical Specifications
| Power Consumption | 3 Watts (Nominal) |
| Accuracy | ±3°C at +25°C |
| Operating Temp | -30°C to +65°C |
| Input Impedance | > 1 MΩ per lead |
Oiltech Controls Limited’s Insight
Engineers prefer the 3500/65-01-00 because it integrates seamlessly into existing racks to manage high-density sensor arrays. It offers superior electrical noise rejection, which is critical for maintaining stable temperature readings in high-EMI industrial zones. This module reduces hardware footprint by consolidating 16 channels into a single full-height slot.
Applications & Diagnostics
Target Assets: Large turbines, centrifugal compressors, and reciprocating engines.
- Diagnostic Ability: Utilizes programmable Alert and Danger delays to filter out transient thermal spikes, ensuring only genuine overheating conditions trigger a machine shutdown.
- Thermal Integrity: Highly accurate detection of bearing wear and cooling system inefficiencies.
Professional FAQ
Can I mix RTD and Thermocouple types?
Yes, the module supports mixed sensor configurations per channel through software selection.
Why is Platinum α=0.00385 the recommended sensor?
It is the global industrial standard; using this type ensures perfect matching with the module’s internal calibration curves.
Is field calibration necessary?
No, the unit is factory-calibrated. All setup and range scaling are managed via the 3500 Configuration Software.
How should I set my alarm delays?
Use longer Alert delays for monitoring trends, and shorter Danger delays (0.5s increments) for instantaneous protection against critical failures.
What occurs during an I/O module mismatch?
The rack will generate an “ADC Failure” and “I/O Module Mismatch” event in the system list, indicating an incompatibility between the I/O and the termination method.
