The Bently Nevada 330104-00-03-90-11-00 Proximity Probe Module is a high-end non-contact eddy current sensor designed for precision measurement of shaft vibration, displacement, and position in mission-critical rotating machinery. As part of the industry-standard 3300 XL 8 mm proximity transducer system, this configuration is engineered for environments where long-distance signal routing, harsh operating conditions, and maximum measurement reliability are required.
This model is distinguished by its 30 mm probe case length, ultra-long 9.0-meter system cable, and FluidLoc cable with armored protection and connector sealing (11 option). These enhancements significantly improve resistance to oil ingress, mechanical stress, and environmental contamination, making it highly suitable for offshore platforms, large turbine trains, and distributed monitoring architectures.
The extended cable length provides exceptional flexibility for installations where monitoring cabinets are located far from the machine, without compromising signal integrity or measurement stability.
