145988-02 | Bently Nevada 3500/65 Temperature Monitor
The Bently Nevada 3500/65 Temperature Monitor is a critical component of the 3500 Series Machinery Protection System, designed to monitor temperature in industrial rotating equipment (e.g., turbines, compressors, motors). Below is a detailed breakdown of its features, functions, and applications:
- Model: 145988-02 (corresponds to the 3500/65 module).
- Manufacturer: Bently Nevada (a leading provider of machinery condition monitoring solutions).
- System Compatibility: Part of the 3500 Series rack - based system, which provides comprehensive protection, monitoring, and control for rotating machinery.
- Function: Monitors temperature signals from sensors (e.g., RTDs, thermocouples) and provides alarms/trips to prevent equipment damage due to overheating.
- Supports multiple temperature sensor types:
- RTDs (Resistance Temperature Detectors): Common types include Pt100 (most widely used), Ni100, and Ni120.
- Thermocouples: Types J, K, T, E, R, S, B, and C.
- Can handle up to 8 channels of temperature inputs per module, enabling simultaneous monitoring of multiple points (e.g., bearing temperatures, winding temperatures).
- Linearization: Converts raw sensor signals into linear temperature values (e.g., °C/°F).
- Alarms & Trips: Provides configurable alarm (high/low) and trip (shutdown) setpoints for each channel to protect equipment.
- Outputs:
- Analog outputs (4–20 mA) for each channel, compatible with DCS/PLC systems.
- Digital outputs (via the 3500 Series communication bus) for status and diagnostics.
- Self-Test Features: Continuously monitors module health, including sensor wiring faults (open/short circuits) and internal component failures.
- Redundancy: Supports hardware redundancy in critical applications (e.g., dual power supplies, dual communication paths).
- Industrial Robustness: Designed for harsh environments (e.g., high vibration, temperature fluctuations) with EMI/RFI immunity.
- Part of the 3500 Series ecosystem, which supports communication protocols like:
- Ethernet (Modbus TCP, Protobuf).
- Serial (Modbus RTU).
- Hardware interfaces (e.g., 4–20 mA, relays).
- Integrates with Bently Nevada’s System 1 software for advanced condition monitoring and predictive maintenance.
