Description
Bently 3500 61
Technical Specifications
- Model Number: 3500/61
- Channel Count: 4 independent temperature channels
- System Compatibility: Bently Nevada 3500 Framework
Key Features
- Comprehensive Alarming: Independent Alert and Danger setpoints for each channel.
- Sensor Break Detection: Automatically detects open-circuit sensor failures and triggers a Not-OK alarm.
- Flexible Scaling: Supports engineering units in Celsius, Fahrenheit, or Kelvin.
Application Scenarios
Critical for protecting oil-film bearings, thrust collars, and stator windings from thermal degradation and catastrophic failure.
Performance Parameters
- Input Impedance: > 100 kΩ for RTD inputs
- Galvanic Isolation: Fully isolated channels to prevent ground loops
Material Composition
High-reliability electronic components with conformal coating to protect against moisture and corrosive industrial atmospheres.
Structural Characteristics
Full-height module featuring front-panel terminal connections and clear LED indicators for power, normal operation, and alarm states.
Working Principle
Conditions the low-level analog signals from temperature sensors, performs high-resolution A/D conversion, and evaluates the data against configured thermal protection limits.
Installation Requirements
Install in any available slot to the right of the TDI module. Ensure proper single-point grounding of sensor shields to prevent electrical noise interference.
Usage Precautions
Do not mix different types of temperature sensors on the same module without verifying individual channel configuration. Regularly calibrate using a precision temperature simulator.
