Bently Nevada 330180-085-03-05 3300 XL Proximitor Sensor

Description

Option 085 (8.5 meters length), Option 03 (armored cable with connector protector), and Option 05 (CSA/ATEX/IECEx approvals) specify this 3300 XL Proximitor Sensor configuration — 330180-085-03-05. This sensor module functions as a signal conditioner, driving the eddy-current proximity probe and translating the high-frequency transducer signal into a proportional displacement voltage. The analog voltage output represents the exact gap change between the probe tip and the observed shaft target area, transmitting directly into machinery protection monitors.

The 330180-085-03-05 configuration is specifically calibrated for an 8.5 m total electrical system length (Option 085) and supports armored extension cabling assemblies paired with integrated fluorosilicone connector protectors (Option 03). Designed for installation in environments demanding rigorous intrinsic safety and non-sparking certifications, it includes comprehensive international approvals (Option 05) such as ATEX, IECEx, and CSA. The module incorporates electrical isolation in its base, removing the necessity of separate insulator plates and facilitating direct DIN rail or panel mounting.

Features

• 8.5 Meter Calibrated Length (Option 085): Generates matching impedance parameters calibrated to an 8.5 m proximity probe and cable configuration, preventing impedance mismatch errors.
• Cabling Armor Integration (Option 03): Formulated to seamlessly match armored extension cables with integrated connector protectors to shield delicate connections from fluids and particulates.
• Agency Approvals (Option 05): Holds CSA, ATEX, and IECEx approvals for safe utilization in hazardous industrial locations.
• RFI/EMI Noise Immunity: Suppresses electrical noise from surrounding radios and variable frequency drives, complying with European CE requirements without requiring specialized metallic conduit.
• SpringLoc Terminals: Uses spring-clamp connections that eliminate screws and prevent the connection degradation typically caused by machine vibration.

Applications

• Shaft radial vibration and dynamic profiling on steam and gas turbines
• Axial position and thrust offset measurement on centrifugal compressor shafts
• Rotor casing expansion and eccentricity monitoring in power generation installations
• Bearing clearance and structural vibration tracking on high-power industrial motors and pumps

Installation Guidelines

• Ensure the industrial terminal block is wired with shielded, twisted-pair cabling to shield the dynamic analog displacement signal from electrical noise.
• Securely clamp the housing onto a standard 35 mm DIN rail or bolt directly to a panel. The integrated base isolation eliminates the need for separate non-conductive isolator plates.
• Avoid sharp bends in any connected probe or extension cabling, maintaining a bend radius above 25.4 mm (1.0 inch) to prevent physical cable damage or signal degradation.
• Connect field wiring by inserting a flat-blade screwdriver to release the spring-clamp inside the terminal, sliding in the stripped wire, and releasing.

Compliance and Certifications

• ATEX/IECEx: Approved for hazardous zone applications as intrinsically safe (Ex ia IIC T4/T5 Ga; Ex ia IIIC T90C/T105C Dc) or non-sparking (Ex nA IIC T4/T5 Gc; Ex ec IIC T4/T5 Gc).
• CSA: Certified for Class I, Division 1, Groups A, B, C, and D hazardous environments when paired with intrinsically safe barriers.
• CE Mark: Complies with standard European RFI/EMI directives without requiring high-cost metallic conduit.
