Technical Hardware Specifications

Mechanical Monitoring & Eddy-Current Validation

The 3300 XL transducer system relies on an eddy-current principle to measure the distance between the probe tip and a conductive target. Proper operation requires gap voltage validation; typical mid-range target values are approximately -10 VDC when operating in the linear range. Rotor dynamics analysis depends on these probes providing high-frequency response signals. To ensure measurement integrity, cross-talk suppression is maintained by adhering to minimum probe spacing requirements, which prevents interference between adjacent probes operating at identical carrier frequencies.

Mechanical Installation Directives

• Mount the probe using an appropriate bracket system to prevent excessive mechanical resonance.
• Ensure the probe is tightened to the required torque specification to prevent backing out during high-vibration machine operation.
• Verify the gap voltage using a digital multimeter at the terminal block before finalizing the calibration.
• Protect the coaxial connector from fluid ingress using the provided ClickLoc protector.

Frequently Asked Questions

• What is the maximum frequency response of this 8 mm probe?

  The probe system provides a frequency response of 0 Hz to 10 kHz (-3 dB).

• How does the connector protector function?

  It creates a seal over the miniature coaxial connection to prevent oil and moisture contamination of the contact surfaces.

• Can this probe be used in hazardous locations?

  Yes, the 05 suffix indicates compatibility with various international agency approvals for explosive environments.

• What is the required supply voltage for the 3300 XL system?

  The probe is passive; it requires the Proximitor Sensor to supply -24 VDC excitation power.

• Does the cable length affect the system calibration?

  Yes, the system is calibrated for a specific total length (1.0 meter). Field modification of cable length is not permitted.

• What is the purpose of the -10 VDC gap voltage target?

  This voltage ensures the probe tip is positioned in the center of the 2 mm linear range for optimal signal swing.

• How should the coaxial cable be routed?

  Route cables in grounded metallic conduit to minimize electromagnetic interference and potential signal noise.

• What is the material of the probe tip?

  The tip is constructed from Polyphenylene Sulfide (PPS) to provide chemical resistance and mechanical durability.
