Bently Nevada 330730-080-00-00 Proximity Transducer System

Reliable Vibration and Displacement Measurement for Industrial Machinery

The Bently Nevada 330730-080-00-00 3300 XL 11 mm Proximity Transducer System provides accurate and non-contacting vibration and displacement measurements. It is designed specifically for fluid film bearing machines, offering a linear output of 3.94 V/mm (100 mV/mil). This system is particularly useful for applications that require extended linear range, such as axial position measurements, ramp differential expansion on steam turbines, and rod position monitoring in reciprocating compressors.

The 3300 XL 11 mm system includes three key components: the 3300 XL 11 mm probe, the 3300 XL 11 mm extension cable, and the 3300 XL 11 mm Proximitor Sensor. Each part of the system is designed to work seamlessly together to provide high-precision monitoring for critical industrial machinery.

Key Features

Extended Linear Range: With a tip size of 11 mm, the system offers a longer linear range than the standard 8 mm version.
High-Precision Measurement: The system delivers a 3.94 V/mm output for accurate displacement and vibration readings.
Versatile Applications: It is suitable for axial position, differential expansion, rod drop measurements, and phase reference signals.
System Compatibility: The 3300 XL 11 mm system is fully compatible with 3500 Monitoring Systems and replaces older 7200-series transducer systems.

System Components

The 3300 XL 11 mm Proximity Transducer System consists of the following components:

3300 XL 11 mm Probe: Engineered for precise non-contacting measurements in harsh environments.
3300 XL 11 mm Extension Cable: Available in various lengths to suit your installation needs.
3300 XL 11 mm Proximitor Sensor: This sensor processes input signals from the probe to provide accurate output for monitoring.
