Quick Detail

Description

The 84140-01 Relay Card is an integral part of the Bently Nevada 3300 XL 11 mm Proximity Transducer System, designed for precise machinery monitoring and automation. This module supports full integration with 3300 XL probes, extension cables, and Proximitor sensors. Operating over a wide temperature range of -52°C to +177°C, the 84140-01 ensures continuous performance in extreme industrial environments.

Equipped with gold-plated brass ClickLoc connectors, the 84140-01 secures reliable electrical connections, while the CableLoc design maintains a 330 N pull strength between the probe cable and probe tip. Patented TipLoc molding technology reinforces probe tip attachment, and optional FluidLoc protection prevents oil or liquid ingress through cables. Recommended connector protectors further safeguard the installation, supporting robust automation systems.

This module is suitable for real-time monitoring applications where accurate relay outputs are critical for automated machinery protection, integrating seamlessly with other 3300 XL system components to ensure precise signal processing and operational control.

Applications

Power Generation: Steam Turbine and Generator Monitoring: As part of the Mechanical Protection System (MPS), it receives signals from shaft displacement or vibration sensors. Upon detecting an anomaly, it executes alarm or emergency trip commands via integrated relay contacts to prevent turbine damage.

Boiler Feed Pumps and Fans: Monitors the vibration status of critical auxiliary equipment in power plants to ensure continuous power production.

Oil & Gas: Centrifugal Compressor Protection: Used in refineries and gas processing plants to monitor the mechanical health of compressor bearings in real time and forwards data to the DCS system for trend logging.

Pipeline Booster Stations: Provides hardware-level safety interlock protection for remote, unattended pump stations.

Petrochemicals: Reactor Agitators and Large Pump Sets: In high-temperature, high-pressure production processes, it monitors the mechanical status of driven equipment in real time, reducing the risk of unplanned downtime.

Specifications
