Quick Detail

Description

The 330780-51-05 is a state-of-the-art 3300 XL 11 mm Proximitor Sensor, representing a significant evolution in the Bently Nevada condition monitoring ecosystem. Designed as a high-fidelity signal conditioner and amplifier, this Proximitor sensor is the critical link between an 11 mm eddy current proximity probe and the monitoring system. It powers the probe, processes the raw gap voltage signal, and outputs a precise, high-level signal proportional to the distance between the probe tip and the target shaft, enabling accurate measurement of both dynamic vibration and static position. This specific model is engineered to deliver superior reliability and is a cornerstone component for building robust machinery protection systems in the most demanding industrial environments.

A primary application for this advanced 3300 XL sensor is the seamless and comprehensive upgrade of legacy 7200-series Transducer Systems. Unlike partial retrofits, the 330780-51-05 is designed to be deployed as part of a complete 3300 XL 11 mm system, which includes matching 11 mm probes and extension cables. This full-system approach is crucial to ensure optimal performance, maintain measurement accuracy, and guarantee system stability, effectively future-proofing critical asset monitoring. The sensor features a compact, DIN mount compatible design with overall case dimensions of 50 mm and a total integrated system length of 5.0 meters (16.4 feet), facilitating straightforward installation in new or existing control panels and cabinets.

Applications

This 3300 XL 11 mm Proximitor Sensor is the ideal electronic cornerstone for upgrading legacy monitoring systems, specifically engineered to replace older 7200-series Transducer Systems. It is deployed in power generation plants and heavy industrial facilities to modernize the monitoring of large steam and gas turbines, generators, and critical pumps. Its wide operating temperature range (-48°C to +174°C) and stable signal conditioning ensure reliable performance in both the high-heat environments near turbines and the cooler ambient conditions of control rooms, providing accurate vibration and position data necessary for protecting these high-value assets.

In the oil, gas, and petrochemical industries, the sensor is utilized for continuous condition monitoring of high-speed machinery such as centrifugal compressors, turbo-expanders, and pipeline pumps. Its multiple agency approvals make it suitable for installation in potentially hazardous areas requiring compliance with stringent safety standards. The integrated 5.0-meter system length and DIN mount design allow for flexible and secure installation within explosion-proof enclosures or control panels, while its low supply sensitivity guarantees accurate data transmission even with electrical noise common in refinery and offshore platform environments.

Specifications

Competitive Advantage

1.Engineered for Seamless Legacy System Modernization

The 330780-51-05 is specifically optimized as a high-performance replacement for obsolete 7200-series systems. It enables a complete, hassle-free upgrade path to the advanced 3300 XL platform, ensuring full component compatibility and eliminating the performance gaps and integration issues associated with mixed-vendor or partial retrofits. This provides a clear, reliable strategy for modernizing condition monitoring infrastructure while protecting existing investments.

2.Superior Signal Integrity in Electrically Noisy Environments

This sensor is designed to deliver exceptional signal fidelity critical for accurate diagnostics. Its very low output resistance of 46 Ω, combined with a specified low extension cable capacitance (69.8 pF/m), significantly reduces signal attenuation and enhances immunity to electromagnetic interference (EMI/RFI). Furthermore, its excellent supply sensitivity (less than 2 mV/V) ensures the output voltage remains stable and accurate despite fluctuations in the input power supply, guaranteeing reliable data for critical machinery protection decisions.

3.Robust Design for Maximum Installation Flexibility and Endurance

Offering exceptional environmental resilience, the sensor operates flawlessly across an extreme temperature range of -48°C to +174°C, suitable for virtually any industrial setting. Its compact, lightweight form factor with a standard DIN mount and a pre-integrated 5.0-meter cable (system length) simplifies installation in space-constrained panels. Compliance with multiple agency approvals ensures it meets global safety and regulatory standards, facilitating its use in regulated projects worldwide without compliance concerns.
