Bently Nevada 1034549-40 | Dual-Channel Temperature Monitor | FieldMonitor 1701/10 Series

Product Description:

The Bently Nevada 1034549-40 is a precision Dual-Channel Temperature Monitor designed for integration within the FieldMonitor 1701/10 series. It specializes in monitoring critical thermal conditions in rotating machinery, ensuring the protection of components such as bearings, motor windings, and process fluids. Widely used in Solar Turbines and other high-performance equipment, the module helps prevent catastrophic failures by providing real-time temperature data and alarm logic for crucial components.

Key Features & Functions:

1. Versatile Sensor Compatibility:

The 1034549-40 supports a wide range of temperature sensors, allowing for easy integration with the most common industrial temperature transducers:

• RTDs: Compatible with both 3-wire and 4-wire RTDs, ideal for compensating lead-wire resistance.

• Thermocouples: Works with Type J/K thermocouples and includes Cold Junction Compensation (CJC) for high accuracy.

2. Real-Time Temperature Monitoring:

This module processes input signals from temperature sensors to monitor various critical machine components, such as:

• Bearing Temperatures

• Winding Temperatures

• Process Fluid Temperatures

With an accuracy of ±1.0°C (±1.8°F) at 25°C, the 1034549-40 ensures that temperature readings are reliable and precise, even in challenging industrial environments.

3. Flexible Alarm Configuration:

The 1034549-40 comes with built-in alarm logic to provide early warning of potential issues. It features two distinct alarm stages:

• Alert (Alarm 1)

• Danger (Alarm 2)

Users can customize alarm setpoints and adjust alarm behavior, including options for Latching or Non-Latching alarms. Alarm delays can be programmed between 0.15 and 20 seconds to avoid false trips.

4. Redundancy & Safety:

Designed with system reliability in mind, this module offers several redundancy options:

• Voting Logic: Supports 1-out-of-2 or 2-out-of-2 voting in conjunction with other FieldMonitor modules, enhancing safety.

• Self-Diagnostics: Constantly monitors sensor wiring for Open Circuit or Short Circuit conditions. If a sensor fails, the module triggers a NOT OK status, preventing false readings and ensuring accurate protection.

5. Distributed Protection:

The 1034549-40 is a distributed protection module that can be mounted directly near the machinery. This minimizes the need for long thermocouple extension cables and reduces the risk of signal noise interference. It is ideally suited for critical machinery in industries like power generation and petrochemical processing.

6. Integration with Solar Turbines:

Commonly deployed in Solar Mars, Centaur, and Taurus gas turbines, this module monitors key parameters such as:

• Bearing Temperatures

• Exhaust Gas Temperatures (EGT)

Its seamless integration into control panels helps protect critical assets from thermal damage.

Technical Specifications:

Configuration and Setup:

The 1034549-40 is easily configured using the FieldMonitor Configuration Software. Users can define setpoint levels for alerts, configure latching or non-latching alarms, and adjust filter settings to smooth out transient thermal spikes, ensuring optimal monitoring and protection.

Applications:

• Solar Turbines: Used in Mars, Centaur, and Taurus turbines for monitoring bearing temperatures and exhaust gas temperatures (EGT).

• Industrial Pumps & Fans: Ideal for temperature monitoring in power generation and petrochemical industries.

• Large Motors: Ensures critical winding and bearing temperature monitoring in large electric motors.
