Hardware Specifications

Rotor Dynamics And Gap Voltage Validation

• Gap Voltage Target: Configured to output a direct voltage proportional to distance, targeting -10 VDC to -12 VDC during cold static positioning.
• Eddy-Current Scaling: Translates magnetic field fluctuations into precise displacement signals for radial vibration and axial position monitoring.
• Cross-Talk Suppression: Employs coaxial shielding and matched electrical matching networks to isolate high-frequency interference on extended cable runs.
• Frequency Response: Delivers linear output performance from 0 Hz (static position) up to 10 kHz (dynamic vibration) across fluid-film bearing setups.

Bill Of Delivery

• 1 x Bently Nevada 330194-00-07-10-05 Proximity Probe
• 1 x Integrated probe tip with 1.0 meter armored cable

Mechanical Mounting And Cabling Guidelines

• Thread Engagement: Install the M10 x 1 threaded body into the machine housing while ensuring maximum thread engagement does not exceed 15 mm to prevent mechanical binding.
• Torque Specifications: Apply calibrated torque wrenches to avoid over-tightening the probe case against the mounting aperture.
• Cable Routing: Keep coaxial signal leads clear of high-voltage motor power cables to minimize electromagnetic coupling into the monitoring channel.
• Grounding Standards: Terminate probe shield drains exclusively at the Proximitor sensor ground stud to avoid ground loops.

Frequently Asked Questions

• Question: What is the primary function of the 330194-00-07-10-05 probe?

  Answer: It converts physical distance between the probe tip and a conductive target into an electrical voltage signal for vibration analysis.

• Question: Does this sensor require external electrical power?

  Answer: No, it operates passively, receiving excitation current from a compatible 3300 XL Proximitor Sensor.

• Question: What thread size does the probe housing feature?

  Answer: The unit is machined with an M10 x 1 thread pattern for direct machinery port insertion.

• Question: What is the maximum allowable thread engagement?

  Answer: Thread engagement must be kept under 15 mm to avoid structural binding or thread stripping during installation.

• Question: Can this ETR probe be paired with standard extension cables?

  Answer: Yes, extended temperature range components are fully compatible with standard 3300 XL extension cables.

• Question: What is the standard static gap voltage setting?

  Answer: The gap is typically adjusted to yield between -10 VDC and -12 VDC during initial cold alignment.

• Question: What hazardous location certifications apply to this part?

  Answer: It includes CSA, ATEX, and IECEx agency approval options for explosive industrial environments.

• Question: What is the weight of the packaged unit?

  Answer: The estimated shipping weight of the item is 0.24 kg.
