Features:
- Extended Linear Range for Critical Machinery Protection
- Non-Contact Vibration and Displacement Measurement Technology
- Seamless Integration with 3300 XL Monitoring Systems and Bently Nevada Machinery Protection Platforms
The Bently Nevada 330780-50-00 operates as a 3300 XL 11 mm Proximitor Sensor, providing precise non-contact measurement of shaft vibration, position, and speed on fluid-film bearing machines. 330780-50-00 continuously converts eddy current variations into a 3.94 V/mm (100 mV/mil) linear output signal, enabling accurate monitoring of axial position, differential expansion, and phase reference across its extended 4.0 mm (160 mil) linear range. This extended range capability is standard with 330780-50-00, and using this sensor in conjunction with 3300 XL monitors allows detection of larger shaft movements that exceed the capabilities of standard 8 mm probe systems.
330780-50-00 provides essential measurement functions critical to rotating machinery protection, and is a fundamental component of the vibration monitoring path, directly affecting the accuracy and reliability of the overall machinery protection system. One 330780-50-00 probe system per measurement point is required, consisting of the probe, extension cable, and Proximitor sensor. 330780-50-00 occupies a dedicated channel input on the monitoring system and is always configured as part of a complete 3300 XL transducer system.
For redundant measurement applications, the 3300 System may require a second 330780-50-00 probe installed at the same measurement plane. In addition to standard single probe operation, the redundant configuration also performs cross-channel verification. The 3300 monitoring system executes validation using the internal comparison logic specified in the monitor configuration. Using this method, the redundant probe system continually monitors the health of both measurement channels. If the system detects that the primary 330780-50-00 probe is no longer providing stable output (outside configured linear range or signal quality thresholds), it will automatically alert operators through the monitor's alarm system and place an event in the System Event List.
The 330780-50-00 Bently Nevada 3300 XL 11 mm Proximitor Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
