Physical and Electrical Specifications

Mechanical Monitoring Characteristics

The probe functions as part of an eddy-current proximity system, where a high-frequency radio signal generates a magnetic field at the probe tip. Variations in the distance between the probe and the metallic target (rotor) result in changes in eddy-current energy absorption. The Proximitor sensor converts this impedance change into a voltage signal proportional to the gap. Proper operation requires a linear range validation; typically, the system is calibrated to a -10 VDC target at a nominal gap of 1.27 mm (50 mils). Cross-talk suppression is maintained by adhering to minimum mounting clearance guidelines relative to other probes.

Shipment Contents

• 330105-02-12-10-02-00 Proximity Probe

• Integrated coaxial cable with Miniature ClickLoc connector

• Protective thread caps

• Note: Calibration documentation and mounting brackets are not included unless specified in the purchase order.

Mechanical Installation Requirements

• Ensure the target surface is free of deep scratches, burrs, or surface discontinuities.

• The probe must be mounted perpendicular to the target surface.

• For reverse mount configurations, verify the probe is installed from the internal side of the housing.

• Use the 3/8-24 UNF threads to secure the probe, ensuring the locking nut is tightened to prevent vibration-induced loosening.

• Maintain a minimum distance of 3 times the probe diameter from any other conductive material to prevent signal interference.

Logistics and Handling

• Delivery time: 3-5 days after payment completion.

• Logistics partners: DHL, FEDEX, or UPS.

• Packaging: All units are secured in anti-static industrial packaging to ensure transit safety and protection against electrostatic discharge (ESD).

Technical Support Inquiries

• Q: What is the primary purpose of the ClickLoc connector?

  A: It provides a secure, vibration-resistant connection for the coaxial cable, ensuring consistent signal integrity between the probe and the Proximitor.

• Q: Can this probe be used with non-XL series sensors?

  A: Yes, the 3300 XL components are backward compatible with 3300 series 5 mm and 8 mm transducer systems.

• Q: What is the effect of probe gap on output voltage?

  A: The output voltage increases linearly as the gap between the probe tip and the target increases.

• Q: Is the cable length field-adjustable?

  A: No, the total system length is calibrated for a specific cable length to maintain impedance matching; altering the length will affect accuracy.

• Q: How should the probe be grounded?

  A: The system should be grounded at the Proximitor sensor end, following the standard site instrumentation earthing practices.

• Q: What is the maximum operating temperature?

  A: The probe is designed for operation in harsh industrial environments; refer to the specific 3300 XL system datasheet for temperature derating curves.

• Q: Does the probe require a specific target material?

  A: It is designed for 4140 steel targets; using other materials will require a recalibration of the scale factor.

• Q: What is the thread pitch for the mounting body?

  A: The mounting body features 3/8-24 UNF threads for precise mechanical positioning.
