The Bently Nevada 330104-00-08-05-02-00 serves as the primary 330104 Proximity Probe utilized to execute non-contact shaft displacement tracking across 3300 or 3500 Turbine Supervisory Instrumentation (TSI) platforms. Configured with a standard 8 mm tip, the transducer monitors dynamic oil-film clearances by feeding raw radio-frequency inductive variables back to an external impedance-matched processing oscillator circuit.

Physical and Electrical Parameters

Eddy-Current Probe Scaling and Rotor Dynamics

This 8 mm sensor tip relies on specialized eddy-current probe scaling to establish a linear range of 2.0 mm (80 mils), yielding a standard scale factor of 7.87 V/mm (200 mV/mil) when matched with a corresponding Proximitor. Mechanical positioning requires rigid gap voltage validation to lock the idle output at a -10 VDC targets benchmark, positioning the probe tip precisely in the center of its electrical range relative to the rotor dynamics centerline. The internal coil geometry maintains high cross-talk suppression, blocking mutual electromagnetic coupling when pairs of transducive tips are aligned on adjacent radial planes.

Field Component FAQ

Q: How does the 0 mm unthreaded length option affect installation inside bracket assemblies?

A: A 0 mm unthreaded selection indicates that the M10 x 1 threads run continuously up to the rear of the 8 mm tip. This permits full thread engagement through the mounting bracket, allowing the entire 80 mm case to remain rigidly stabilized against machine vibration.

Q: Can this 0.5 meter probe connect directly to a 3500 monitoring card without an extension cable?

A: No. The underlying Proximitor circuit requires an exact total electrical length configuration of either 5.0 meters or 9.0 meters. Connecting this 0.5 meter probe directly without a matching 4.5 meter or 8.5 meter extension cable corrupts the eddy-current probe scaling, inducing severe measurement errors.

Q: What protection does the integrated armor provide against physical damage?

A: The flexible stainless steel armor prevents aggressive mechanical wear, cuts, and crushing loads on the internal coaxial line. However, it does not provide gas-tight sealing, meaning liquid contaminants must still be managed via standard conduit routing.

Mechanical Installation and Isolation Directives

• Thread Seating Alignment: Ensure at least 5 full threads of engagement into the mounting bore before applying torque to avoid stripping the fine M10 x 1 thread paths.

• Locknut Stabilization: Once gap voltage validation achieves the -10 VDC targets centerline, secure the companion locknut to prevent physical movement caused by low-frequency rotor dynamics.

• Coaxial Connector Booting: Clean the miniature coaxial ClickLoc junction of all conductive oils, snap the connection together tightly, and slide the translucent insulation sleeve over the joint to isolate it from the machine frame.

• Armor Bend Limitations: Do not bend the armored outer casing past a minimum radius of 25.4 mm (1.0 inch) during cable routing to prevent buckling the inner conductor layer.

Dispatch Package Elements

• Standard Line Components: One 330104-00-08-05-02-00 armored proximity probe, locknut hardware, and one clear connector insulation cylinder.

• Separate Procurement Items: External matching Proximitor modules, extension cables, and specialized panel-mount junction boxes must be ordered as independent line items.

Cargo Handling and Delivery Data

• Logistics Handling Time: Delivery time: 2-7 days when payment finish, utilizing prioritized air courier options through DHL, FEDEX, or UPS.

• Structural Freight Guarding: Sealed in specialized anti-static industrial packaging using reinforced linear transit tubes to protect the 80 mm case and 0.5 meter armored lead from physical bending or shock during overseas transport.
