Bently Nevada 82369-01 4-Wire RTD Input Module

Product Overview

The Bently Nevada 82369-01 is a high-precision 4-wire RTD input module for the 3300/35 system. It provides independent monitoring for six channels, effectively canceling lead-wire resistance to ensure superior accuracy over long distances. 

Technical Specifications

• Part Number: 82369-01.

• Manufacturer: GE / Bently Nevada.

• Product Family: 3300/35 Six-Channel Temperature Monitor.

• Input Configuration: 4-Wire RTD.

• Number of Channels: 6 Independent Channels.

• Mounting: Rear-rack I/O slot.

• Compatibility: Integrates with 3300 Series Machinery Protection Racks.

• Condition: Industrial-grade, high-durability construction.

Key Features and Engineering Advantages

• Six-Channel Capacity: Monitors up to six distinct temperature points (such as bearing metal or winding temperatures) within a single rack slot, maximizing system density.

• 4-Wire Precision: The 4-wire measurement technique is the most accurate method for RTD sensing, as it eliminates errors caused by the resistance of the field wiring between the sensor and the rack.

• On-Line Monitoring: Provides continuous, real-time temperature data, allowing for immediate "Alert" or "Danger" alarms if machinery starts to overheat.

• Universal RTD Support: While typically configured for standard platinum (Pt100) sensors, the 3300/35 system is versatile enough to be adapted for various RTD types used in industrial motors and generators.

• Robust Termination: The screw-terminal interface is designed for high-vibration environments, ensuring that sensor leads remain securely connected during years of operation.
