Description

Option 90 (9.0 meters system length, panel mount) and Option 05 (CSA, ATEX, IECEx approvals) specify this 3300 XL Proximitor Sensor configuration — 330180-90-05. This non-contacting sensor is a core conditioning module for Bently Nevada 3300 XL proximity transducer systems, which are used to measure radial shaft vibration, axial thrust position, and speed on rotating industrial machinery. The unit houses specialized oscillator and demodulator circuitry that generates a radio frequency signal, drives the connected eddy-current probe, and conditions the returning signal into a continuous analog voltage proportional to the dynamic gap distance.

This panel-mount variant features a standardized 4-hole mounting plate that shares an identical footprint with older Proximitor designs, simplifying legacy upgrades. The aluminum mounting base provides built-in electrical isolation, removing the requirement for separate isolator plates. Calibrated for 9.0-meter systems, the 330180-90-05 requires precise matching with a 3300 XL 8 mm proximity probe and extension cable that sum to a total physical length of exactly 9.0 meters. Option 05 compliance adds certified protection for hazardous locations, enabling safe deployment under global intrinsic safety and non-sparking/non-incendive standards.

Features

Installation Guidelines

• Mount the Proximitor sensor on a clean, flat surface using the integrated panel-mount base; the mounting base provides integral electrical isolation directly.
• Use tinned 3-conductor shielded triad field wiring cable with wire sizes ranging from 0.2 mm2 to 1.5 mm2 (16 AWG to 24 AWG).
• Insert wires directly into the SpringLoc terminal strip; no special insertion or clamping tools are required.
• Limit total field wiring between the Proximitor sensor and the monitoring system to a maximum of 305 meters (1000 feet) to prevent high-frequency signal roll-off.
• Ensure that probe and extension cables maintain a minimum bend radius of 25.4 mm (1.0 inch) during routing.
• For hazardous locations, follow the certified wiring diagrams for intrinsically safe or non-incendive/non-sparking requirements.

Compliance and Certifications

• EMC Standards: EN 61000-6-2 (Immunity for Industrial Environments), EN 61000-6-4 (Emissions for Industrial Environments)
• Environmental Compliance: CE mark, RoHS Directive 2011/65/EU, China RoHS compliance (EFUP 15 years)
• Functional Safety: SIL 2 certified (Hardware Fault Tolerance HFT = 0), SIL 3 capable in redundant (HFT = 1) systems
• Hazardous Area Approvals (Option 05): CSA, ATEX, and IECEx certifications for intrinsically safe (ia) and non-incendive/non-sparking (nA, ec) installations in Class I, Division 1/2 and Zone 0/2 hazardous environments
