Description

The Bently Nevada 330780-50-00 is a 3300 XL 11 mm Proximitor Sensor designed for high-precision vibration and position monitoring in industrial rotating machinery. This sensor is a critical component of the 3300 XL 11 mm Proximity Transducer System, which is engineered to measure static and dynamic gaps between the probe tip and the observed target, such as a machine shaft.

Features

• Designed for 11 mm probe systems to provide extended linear range compared to standard 8 mm systems.
• System length of 5.0 meters (16.4 feet) for flexible installation in large machinery environments.
• Robust construction with AISI 304 stainless steel probe housing for durability in harsh industrial conditions.
• High-frequency response suitable for detecting vibration, axial position, and speed measurements.
• Standard output resistance of 50 Ohm for compatibility with Bently Nevada monitoring racks.

Technical Specifications

Installation Guidelines

• Ensure the Proximitor sensor is mounted in a protected, dry location, preferably within a weather-proof housing or control cabinet.
• Use shielded coaxial cables for all connections to minimize electromagnetic interference (EMI).
• Maintain proper grounding practices to ensure signal integrity and prevent ground loops.
• Verify that the system length (probe + extension cable) matches the calibrated length of the Proximitor sensor to maintain measurement accuracy.
• Power down the monitoring system before connecting or disconnecting the sensor to prevent electrical damage.

FAQ

What is the primary function of the 330780-50-00?

This sensor is used to convert the gap between the probe tip and the target into a proportional voltage signal, which is then processed by the Bently Nevada monitoring system to determine vibration or position data.

Can this sensor be used with 8 mm probes?

No, the 330780-50-00 is specifically calibrated for the 3300 XL 11 mm transducer system. Using it with a different probe size will result in incorrect output signals and calibration errors.
