Description

Option 50 (5.0 m system length, panel mount) and the -CN China hazardous area approval package specify this 3300 XL Proximitor Sensor configuration — 330180-50-CN. This sensor conditions and drives the signal for 3300 XL 8 mm proximity probes, translating the high-frequency eddy-current signal into a proportional DC voltage displacement output for machinery protection and condition monitoring systems.

Unlike 1.0 m or 9.0 m variants, the Option 50 system length must be matched with a 5-meter probe and extension cable combination to form a calibrated 5.0-meter transducer loop. The panel-mount design offers a standard four-hole mounting footprint that is physically interchangeable with legacy Bently Nevada Proximitor sensors, while the integrated electrical isolation in the housing base eliminates the requirement for additional isolator plates. The -CN approval package ensures full compliance with local Chinese hazardous area regulatory frameworks, including NEPSI and CCC certifications, allowing safe deployment in explosive environments.

Features

• Option 50 configuration provides compatibility with 5.0-meter transducer systems (probe plus extension cable totaling 5 meters).
• Panel-mount housing features a traditional four-hole footprint, allowing simple mechanical drop-in replacement.
• -CN China approval package adds verified CCC and NEPSI hazardous area safety compliance.
• Built-in electrical isolation in the mounting base eliminates the need for separate isolator plates.
• SpringLoc terminal block ensures secure, tool-free field wiring that resists loosening under vibration.
• Highly immune to radio frequency interference (RFI) and electromagnetic interference (EMI), satisfying European CE requirements without metal conduit.

Applications

This 3300 XL Proximitor Sensor is used for rotating machinery monitoring. Common applications include:

• Shaft dynamic vibration and axial position measurement on steam and gas turbines.
• Radial dynamic motion and casing vibration monitoring in centrifugal compressors.
• Rotor position and bearing clearance tracking on heavy-duty electric motors and pumps.
• Reciprocating compressor rod position and crosshead vibration monitoring.

Installation Guidelines

Follow these mechanical and electrical installation guidelines for the 330180-50-CN Proximitor Sensor:

• System Length Matching: Pair this sensor only with a 5.0-meter probe and extension cable combination (such as a 1.0 m probe plus a 4.0 m extension cable). Mismatched lengths degrade calibration.
• Electrical Isolation: The mounting base provides electrical isolation from the panel surface. Ensure mounting screws are tightened to secure the unit without bypassing this built-in isolation.
• Wiring Connections: Use tinned, three-conductor shielded triad field wire (0.2 to 1.5 mm2 or 16 to 24 AWG). Insert wires into the SpringLoc terminal blocks until clamped.
• Maximum Distance: Keep field wiring between the Proximitor sensor and the monitoring rack under 305 meters (1,000 feet) to prevent signal loss.

Compliance and Certifications

The Bently Nevada 330180-50-CN conforms to the following standards and approvals:

• CCC (China Compulsory Certification): Certified for explosive and hazardous environments in China.
• NEPSI (National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation): Intrinsic Safety and Non-Incendive approvals for hazardous areas in the People's Republic of China.
• CE Mark: Fully compliant with EU electromagnetic compatibility directives without metallic conduit requirements.
