The Bently Nevada 330104-00-04-50-11-00 Proximity Probe Module is a precision-engineered eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, displacement, and position in critical rotating machinery. As part of the widely deployed 3300 XL 8 mm proximity transducer system, this model delivers exceptional signal stability, rugged mechanical strength, and long-term operational reliability in demanding industrial environments.
This configuration includes a 40 mm probe case length (code 04), a 5.0-meter system cable length (code 50), and a FluidLoc + ClickLoc connector system (code 11). The FluidLoc design enhances resistance to oil ingress and moisture contamination, making it particularly suitable for turbine trains, compressors, and oil & gas applications where environmental exposure is severe.
With its extended cable reach and reinforced sealing architecture, this probe is optimized for installations where monitoring systems are located far from rotating equipment, without compromising measurement accuracy or signal integrity.
