Reliable Shaft Monitoring Technology for Critical Assets
The 162381-064-028-50-05 belongs to the Bently Nevada 3300 XL 8 mm proximity probe family, a widely adopted platform for non-contact measurement of rotating shaft movement. The probe operates by generating an electrical output proportional to the distance between the probe tip and the conductive shaft surface, allowing both dynamic vibration and static position measurements.
This model configuration is designed with a 6.4-inch probe length, 8 mm probe diameter, and 5-meter cable length, making it suitable for installations requiring additional mounting depth while maintaining the standard performance characteristics of the 3300 XL monitoring system.
The probe is typically installed together with a compatible 3300 XL extension cable and 3300 XL Proximitor Sensor to create a complete vibration and position monitoring chain.
