Description

The Bently Nevada 330780-90-00 is a high-performance 3300 XL 11 mm Proximitor Sensor designed for precise vibration and position monitoring in industrial rotating machinery. This sensor is a critical component of the 3300 XL 11 mm Proximity Transducer System, which provides accurate gap, amplitude, and position measurements for industrial applications requiring high linearity and stability.

Features

• Designed for 11 mm probe systems to provide extended linear range compared to standard 8 mm systems.
• System length of 9.0 meters (29.5 feet) for flexible installation in large machinery environments.
• Panel mount configuration for secure integration into control cabinets or junction boxes.
• Robust output resistance of 50 Ohm for reliable signal transmission.
• Wide operating temperature range suitable for demanding industrial environments.

Technical Specifications

Installation Guidelines

• Ensure the Proximitor sensor is mounted in a protected, dry environment within a control cabinet or weather-proof enclosure.
• Use only high-quality coaxial cabling and Bently Nevada-approved connectors to maintain signal integrity and system calibration.
• Maintain proper grounding practices for the transducer system to minimize EMI/RFI interference.
• Verify that the system length (probe + extension cable + Proximitor sensor) matches the calibration requirements of the monitoring system.
• Always power down the monitoring rack before connecting or disconnecting sensor leads to prevent potential electrical damage.

FAQ

What is the primary function of the 3300 XL 11 mm Proximitor Sensor?

The sensor acts as the signal conditioning interface for the 11 mm proximity probe. It converts the probe's high-frequency carrier signal into a proportional voltage output that represents the distance between the probe tip and the observed target, such as a machine shaft.

Can this sensor be used with standard 8 mm probes?

No, the 3300 XL 11 mm Proximitor Sensor is specifically calibrated for use with 11 mm probes. Using it with an incorrect probe size will result in inaccurate measurements and invalid system calibration.
