Quick Detail

Description

The 330180-91-CN is a state-of-the-art 3300 XL Proximitor Sensor manufactured by Bently Nevada, serving as the technological heart of the 8mm proximity transducer system. As a high-performance eddy current signal conditioner, this 3300 XL Proximitor Sensor is specifically engineered to convert complex proximity probe signals into stable, linear voltage outputs for machinery protection systems. This specific model features a 9.0-meter system length and a DIN rail mount configuration, providing a robust and organized installation method for high-density control cabinets and monitoring racks. The 330180-91-CN is optimized for industrial rotating machinery, delivering millimeter-precision data on shaft vibration and axial position.

Constructed from premium A380 aluminum, the housing of the 3300 XL Proximitor Sensor offers exceptional thermal stability and mechanical durability. This model is specifically designed to meet the rigorous demands of the Chinese industrial market, carrying the -CN suffix which signifies official NEPSI hazardous area certification alongside global CSA, ATEX, and IECEx approvals. Such comprehensive certification ensures that the 330180-91-CN can be safely deployed in explosive atmospheres common in petrochemical refineries and offshore gas platforms. Its compact physical footprint of 8.6x3.4x7cm allows for seamless integration into existing enclosures without requiring extensive modifications.

Applications

The 330180-91-CN is primarily utilized for Radial Vibration and Axial Thrust Monitoring in large-scale industrial assets such as steam turbines, centrifugal compressors, and power generators. By pairing this 9.0-meter system with an 8mm probe and extension cable, engineers can monitor minute shaft displacements with a standard scale factor of 200 mV/mil. Its DIN rail mount design makes it the preferred choice for centralized monitoring in power plant control rooms, where multiple sensors must be organized efficiently to provide real-time protection against mechanical imbalance or bearing wear.

In the Petrochemical and Oil & Gas sectors, this 3300 XL Proximitor Sensor is an essential component for monitoring equipment located in hazardous zones. Thanks to its NEPSI, ATEX, and IECEx approvals, the 330180-91-CN is safely installed near reactors, agitators, and high-pressure pumps where flammable vapors may be present. The A380 aluminum housing provides the necessary corrosion resistance to withstand salt spray on offshore platforms and harsh chemical exposure in refineries, ensuring long-term signal stability for critical safety-instrumented systems (SIS).

The sensor is also widely implemented for Keyphasor Reference Signal Generation and rotational speed measurement. In high-speed machinery, the 330180-91-CN processes pulses from probes aimed at shaft notches to provide precise timing data for phase analysis. This application is vital for diagnostic teams performing rotor balancing and vibration frequency analysis. Its superior RFI/EMI immunity ensures that the pulse signal remains clean and accurate even when the sensor is located near heavy-duty electric motors or variable frequency drives (VFDs) that generate significant electrical noise.

Specifications

Competitive Advantage

1. Specialized NEPSI and Multi-Agency Safety Certification

The 330180-91-CN is specifically tailored for international and Chinese markets, holding NEPSI, CSA, ATEX, and IECEx certifications. This allows global enterprises to standardize their spare parts inventory across various regions, ensuring that the sensor meets all local legal and safety requirements for explosive environments, thereby reducing procurement complexity and project risk.

2. Advanced RFI/EMI Immunity and Signal Integrity

A major technical advantage is its built-in resistance to electrical interference. The 3300 XL Proximitor Sensor design eliminates the need for expensive, bulky shielded conduits and separate isolator plates. It delivers a clean signal even in "electrically noisy" environments, significantly reducing the frequency of false alarms and improving the overall reliability of the machinery protection loop.

3. High-Density DIN Rail Mounting and Compact Design

With its integrated DIN rail mount and compact 8.6x3.4x7cm dimensions, the 330180-91-CN facilitates high-density installations. This saves valuable space in control cabinets and allows for a more organized wiring layout. The SpringLoc terminal strips ensure that field wiring remains secure under intense machinery vibration, providing a more reliable connection than standard screw-type terminals.
