Capteur Proximitor Bently Nevada 330780-90-00 3300 XL 11 mm

Description

330780-90-00: 3300 XL 11 mm Proximitor Sensor configured with Option 90 for a 9.0 meters (29.5 feet) total system length with panel mount, and Option 00 specifying that agency approvals are not required.

This sensor performs non-contact eddy-current displacement measurements when paired with a compatible 3300 XL 11 mm proximity probe and extension cable. The completed transducer loop outputs a linear voltage signal directly proportional to the distance between the probe tip and the target. This specific 9.0-meter panel-mount configuration differs from the standard 5.0-meter variants (such as Option 50 or 51) and is intended for applications where a longer system length is required to route cabling back to the monitor rack.

Features

• Option 90 specifies a 9.0 meters (29.5 feet) total system length with panel mounting.
• Option 00 means no agency approval is required, suitable for non-hazardous general purpose environments.
• 4.0 mm (160 mils) linear range begins at approximately 0.5 mm (20 mils) from the target.
• A380 aluminum housing provides protection and structural integrity for the sensor electronics.
• Compatible with 3300 XL 11 mm probes and 330730 extension cables to form a complete calibration-aligned monitoring loop.

Applications

• Shaft vibration and axial position measurement on industrial turbines, compressors, and pumps.
• Radial vibration monitoring on large rotating machinery with fluid-film bearings.
• Critical machinery protection systems requiring a 9.0-meter system length.

Technical Specifications

Connections and Interfaces

The Proximitor Sensor features a three-terminal block for field wiring connection:

Installation Guidelines

• Mount the sensor on a flat panel surface using the integrated panel-mount base with 4.0 mm mounting holes.
• Ensure proper electrical isolation by using a mounting pad if necessary.
• Shielded three-conductor triad cable is recommended for field wiring back to the monitor rack.
• Maintain a maximum field wiring distance of 305 meters (1000 feet) to prevent high-frequency signal attenuation.
• Secure the coaxial connections to a finger-tight tightness, up to 0.565 N-m (5 in-lb) maximum torque.

Compliance and Certifications

• FCC Part 15 compliant
• European Community Directive: EMC Directive 2014/30/EU (EN 61000-6-2, EN 61000-6-4)
• RoHS Directive 2011/65/EU
• Functional Safety: SIL 2 (HFT = 0), SIL 3 (HFT = 1)
• Note: Option 00 specifies that hazardous area approvals are not required.
