The Bently Nevada 330103-01-07-50-02-00 serves as the primary 330103 Proximity Probe utilized to execute non-contacting shaft displacement and dynamic vibration measurements across 3300 XL Series platforms. Configured with a smooth cylindrical case design, the hardware projects a high-frequency radio frequency field onto a rotating target surface, converting gap variations into an analog parameter for processing by a matched Proximitor sensor module.

Hardware Specifications

Gap Voltage Validation and Cross-Talk Suppression

The 330103-01-07-50-02-00 probe functions as the front-end inductive loop that dictates system eddy-current probe scaling accuracy. Field installation and calibration loops require positioning the 3/8 in smooth cylindrical probe body within its mounting bore to establish a gap voltage validation target of -10 VDC. This exact center-span coordinate provides full dynamic range tracking for complex rotor dynamics. Rigid mechanical clamping across the 7.0 in case length prevents lateral movement from bearing fluid forces, sustaining high cross-talk suppression between adjacent orthogonal X-Y radial channels.

• One (1) ClickLoc miniature coaxial interface connector insulating sleeve

• Direct factory testing protocol documentation recording calibration linearity

Field Installation Guidelines

• Insert the smooth barrel of the probe body into the machined mounting bore, sliding the assembly inward until the sensor tip encounters the target face.

• Back the probe body out slowly while checking active voltage indicators across the raw signal connections using a calibrated digital voltmeter.

• Secure the mounting clamp hardware onto the smooth barrel once the output signal registers the standard -10 VDC gap validation center point.

• Verify a minimum 15 mm clear radius surrounds the 8.0 mm tip assembly to eliminate structural side-gap interference from altering the factory scale factor.

• Direct the integrated 5.0 m coaxial lead line into designated metal protective conduit networks, connecting cable shields exclusively at the tracking instrument rack chassis.

Delivery Information

Delivery time: 3-5 days when payment finish, distributed worldwide via international express networks including DHL, FEDEX, or UPS. Individual tracking probes are sealed inside vapor-barrier anti-static industrial packaging sheets to protect the miniature ClickLoc coaxial contacts from exposure. Outer transit cartons feature rugged dual-wall corrugated shells lined with custom shock-absorbing molded foam to secure factory sensor calibration against shipping impacts.

Frequently Asked Questions

Q: Can this 5.0 m proximity probe connect directly to a 3500 rack system without an intermediate extension cable?

A: No. A 5.0 m probe assembly requires direct connection to a matched 5.0 m Proximitor sensor module. If a 9.0 m Proximitor module is utilized, a separate 4.0 m extension cable must be placed inline to complete the required 9.0 m total system loop capacitance.

Q: What output indication occurs if the internal probe coil experiences an open circuit or physical cut?

A: An open circuit on the coaxial path causes the downstream Proximitor sensor voltage output to saturate toward the maximum supply limit (approximately -21 VDC). The connected machinery monitor intercepts this voltage error and triggers a "Not OK" system status flag.

Q: Is a smooth case probe better than a threaded case probe for high-vibration bearing caps?

A: Smooth case designs allow continuous axial depth adjustments without thread pitch limitations. However, they require a separate compression or split-collet clamping mechanism to remain locked in position under severe structural mechanical forces.
