Bently Nevada 330780-51-00 3300 XL 11 mm Proximitor Sensor

Description

330780-51-00 specifies the 3300 XL 11 mm Proximitor Sensor configured with a 5.0 meter system length for DIN-rail mounting (Option 51) and without agency approvals (Option 00). It operates as a non-contact eddy-current sensor within 3300 XL 11 mm transducer systems to measure static and dynamic shaft movement. This sensor pairs with a 3300 XL 11 mm proximity probe and an extension cable, converting the relative distance between the probe tip and the target surface into a proportional analog voltage output.

In contrast to sibling options like panel-mount versions (Option 50) or configurations with multiple hazardous area approvals (Option 05), this specific DIN-rail mount configuration fits high-density mounting arrangements within cabinet enclosures. It features high radio frequency (RFI) and electromagnetic (EMI) immunity, which prevents output distortion when located near high-frequency radio transmitters. The integrated SpringLoc terminal strips facilitate fast, secure field wiring connections without requiring specialized installation tools.

Features

• Option 51 specifies a 5.0 meter (16.4 feet) system length designed for standard 35 mm DIN-rail mounting.
• Option 00 indicates a standard configuration without hazardous area agency approvals.
• RFI and EMI shielding protects the sensor output from electromagnetic and high-frequency interference.
• SpringLoc terminal strips provide reliable, secure field wiring connections without requiring specialized tools.
• A380 aluminum housing provides physical protection for the sensor's internal circuitry.
• Output impedance is rated at 50 ohms to match standard coaxial signal transmission lines.

Applications

This sensor is used to support relative vibration and position monitoring in critical industrial machinery, including:

• Turbine and compressor shaft radial vibration and axial position measurements
• Rotor position and axial thrust displacement monitoring
• Keyphasor speed measurements and phase reference checks
• Enclosure-mounted machinery protection systems requiring high-density DIN-rail integration

Installation Guidelines

• Mount the Proximitor Sensor securely on a standard 35 mm DIN-rail. Ensure an additional 3.05 mm (0.120 in) of clearance is available for removing the DIN rail if required.
• Avoid routing field wiring cables next to high-voltage power lines to minimize potential electrical noise injection.
• Use 3-conductor shielded triad cable (0.2 to 1.5 mm2 or 16 to 24 AWG) for field wiring connections between the Proximitor Sensor and the monitoring system.
• Ensure the combined physical length of the proximity probe lead and the extension cable equals the total system calibration length of 5.0 meters.
• Tighten field wiring terminal screws firmly to maintain connection integrity under industrial vibration, utilizing the SpringLoc terminal strips.
