The Bently Nevada 330104-00-08-50-02-00, also cataloged as the 330104 Proximity Probe, operates as a dedicated hardware component for non-contacting shaft displacement tracking within 3300 XL Machinery Protection System platforms. The sensor establishes high-frequency eddy-current paths against a target surface to capture mechanical alterations, transmitting real-time physical position data over an integrated coaxial transmission line to an external matching Proximitor module.

The 330104-00-08-50-02-00 maintains an optimized eddy-current probe scaling profile calibrated for standard AISI 4140 steel targets. The interaction between the 8 mm tip and the target generates a linear scale factor output of 7.87 V/mm (200 mV/mil) over the specified 2.0 mm operational span. Any variance in the electrical conductivity or magnetic permeability of the target metallurgy will shift the nominal voltage response, corrupting the feedback loop during evaluation of absolute rotor dynamics unless a dedicated calibration modification is applied directly at the transmitter level.
Q: Can this 5.0-meter total length probe assembly be connected into a system loop using an intermediate extension cable?
A: No. Transducer calibration requires an exact electrical length match. This 5.0-meter probe must connect directly to a 5.0-meter Proximitor Sensor without any extension cables to prevent impedance mismatching and signal degradation.
Q: Is this specific probe model rated for installation within hazardous areas?
A: No. The option 00 designation specifies that no hazardous area approvals are certified for this hardware block. It must only be deployed within configurations that do not require explosive protection ratings.
