Hardware Specifications

Mechanical Monitoring and Signal Validation

This probe utilizes an eddy-current principle to detect relative motion between the probe tip and the target material. The transducer system relies on an excitation signal from the Proximitor to generate an electromagnetic field. Proper gap voltage validation is performed by ensuring the output remains within the linear range, typically calibrated to -10 VDC at a target gap of 1.27 mm (50 mils). Rotor dynamics analysis requires consistent probe scaling; deviations from this linear range can result in signal distortion or harmonic inaccuracies. Effective cross-talk suppression is achieved by maintaining specified clearance distances when installing multiple probes near the same target location.

Ordering Information

Field Installation Guidelines

• Probe Mounting: Use the M10 x 1 threaded section for mounting; ensure the probe is firmly secured with the provided jam nut to prevent axial movement.

• Alignment: The probe tip must be aligned perfectly perpendicular to the rotor target to ensure accurate gap readings and avoid false vibration data.

• Grounding: Maintain consistent cable shielding continuity to the instrumentation common to minimize electromagnetic interference (EMI).

• Gap Adjustment: Perform the gap setting using a feeler gauge or micrometer while monitoring the system output voltage to ensure the sensor operates in the middle of its linear voltage range.

• Routing: Observe minimum bend radius requirements for the armored cable to avoid internal impedance changes.

Transit and Logistics

• Logistics: Shipped via DHL, FEDEX, or UPS.

• Packaging: All items are sealed in anti-static industrial packaging to prevent electrostatic damage and physical shock during transit.

Frequently Asked Questions

• Q: Does the probe require external power?

  A: No, it is a passive sensor powered by the Proximitor signal from the monitoring system.

• Q: Can this probe be used for high-temperature applications?

  A: The probe is rated up to 177 deg C; verify the application environment against the datasheet for long-term thermal stability.

• Q: How does the armor affect the probe performance?

  A: The armor provides mechanical protection for the coaxial cable but does not impact the electromagnetic signal characteristics of the probe tip.

• Q: Is this probe compatible with non-XL 3300 series Proximitors?

  A: Yes, the 3300 XL probes maintain backward compatibility with previous 3300 series transducer systems.

• Q: What is the purpose of the M10 x 1 thread?

  A: The M10 x 1 thread allows for precise axial adjustment of the probe gap relative to the target machine surface.

• Q: Can I shorten the 1.0 m cable?

  A: No, the system is calibrated for the specific cable length; shortening the cable alters the total system capacitance and signal integrity.

• Q: What should the output be at zero gap?

  A: In a correctly operating system, the probe will encounter the target before reaching zero voltage, typically triggering a "near-gap" state.

• Q: How is the probe grounded?

  A: The probe body is typically grounded through the machine housing, while the cable shield is grounded at the Proximitor terminal.
