Bently Nevada 330103-00-03-05-02-00 3300 XL 8 mm Proximity Probe

The Bently Nevada 330103-00-03-05-02-00, also cataloged as the 3300 XL 8 mm Probe, serves as the primary 3300 XL Proximity Probe utilized to execute static position and dynamic shaft vibration measurements across 3300 Proximity Transducer System platforms.

Hardware Specifications

Dynamic Rotor Behavior & Gap Voltage Validation

The 330103-00-03-05-02-00 reverse-mount probe emits a high-frequency RF field to continuously sense conductive target movements on fluid-film bearing machines. Precise eddy-current probe scaling converts physical displacement into a proportional DC/AC voltage signal transferred via the 3300 XL extension cable. Field setup requires gap voltage validation to adjust the physical probe position until reaching nominal -10 VDC baseline targets at the center of the linear voltage range. Built-in cross-talk suppression ensures signal accuracy during multi-probe installations tracking complex rotor dynamics.

Frequently Asked Questions

Q: What is the primary physical function of the 330103 series reverse-mount design?

A: The reverse-mount configuration allows the probe to be installed from inside bearing housings or specialized brackets, utilizing back-mounting threads to secure the probe body in restricted access points.

Q: How does the ClickLoc connector maintain electrical integrity in high-vibration applications?

A: The ClickLoc miniature coaxial connector features a positive mechanical locking detent mechanism that prevents physical backing-off or signal loss caused by continuous industrial machine vibration.

Field Installation Guidelines

• Secure the reverse-mount body using standard 3/8-24 UNF threaded ports or mounting brackets, ensuring proper thread engagement to prevent physical loosening.
• Monitor output voltage with a digital multimeter connected to the Proximitor test points until reaching the -10 VDC gap voltage validation setting.
• Fully mate the coaxial ClickLoc connectors until the tactile click is felt, confirming positive electrical contact and lock engagement.
• Route signal cables in dedicated grounded metallic conduits to protect low-level RF signals from ambient electromagnetic interference.
