Hardware Specifications

Rotor Dynamics And Eddy-Current Proximity Transducer Performance

The 3300 XL NSv Transducer System maintains a calibrated average scale factor of 7.87 V/mm (200 mV/mil) to execute high-resolution proximity measurements across constrained internal clearances. Rotor dynamics analysis relies on precise signal transmission through the eddy-current probe, requiring rigid gap voltage validation where static target voltages must be adjusted within a -9 V to -11 V DC window. Signal integrity is preserved via matched impedance architecture, preventing cross-talk and suppression anomalies between the sensor tip, the armored extension lead, and the paired Proximitor monitor module.

Ordering Information

• 1 x 330910-00-12-10-02-05 3300 NSv Proximity Probe (M10X1 thread, armored build, 0 mm unthreaded length, 120 mm case length, 1.0 meter cable with ClickLoc connector)

Field Installation Guidelines

• Mechanical Mounting: Thread the probe securely into the M10X1 mounting port, utilizing proper torque metrics to prevent thread binding or mechanical misalignment under heavy centrifugal vibration.
• Connector Engagement: Inspect and clean the miniature coaxial ClickLoc connector before joining, verifying that an audible and tactile click confirms full mechanical seating.
• Bend Radius Limitation: Maintain a minimum bend radius of 25.4 mm (1.0 in) for the armored coaxial cable to eliminate internal conductor fatigue and signal degradation.
• Insulation and Grounding: Apply clear heat-shrink tubing over the interconnect points to isolate the gold-plated brass connectors from direct grounding against machine casings or metallic junction boxes.

Frequently Asked Questions

• What is the primary function of the 330910-00-12-10-02-05 probe?

  The probe converts mechanical air gap variations between its tip and a rotating shaft into an analog electrical signal for vibration monitoring.

• What thread standard is utilized on this specific probe casing?

  The unit is manufactured with an M10X1 thread specification incorporating integrated stainless steel armor protection.

• Does this sensor require an external DC power supply?

  No. As a passive inductive transducer component, it operates entirely on the excitation voltage loop supplied by the connected Proximitor sensor.

• How should the initial mechanical gap be set during installation?

  The probe-to-target gap must be adjusted until the static output voltage reaches the recommended linear range between -9 V and -11 V DC.

• What precautions apply to the coaxial ClickLoc connector?

  Ensure connectors are completely clean and dry, and verify a distinct click is felt to guarantee proper pin engagement and low contact resistance.

• What is the specified minimum bend radius for the armored cable?

  The armored cable must never be bent tighter than a 25.4 mm (1.0 in) radius to protect internal conductors from mechanical damage.

• Can this probe tolerate high operating temperatures?

  Yes, the probe assembly withstands continuous operational temperatures ranging from -51 deg C up to +177 deg C at the tip.

• What target size restrictions apply to the NSv transducer series?

  The NSv architecture is designed for small target measurements, supporting radial vibration on shafts under 51 mm and axial positions under 15 mm.
