Hardware Specifications

Mechanical Monitoring & TSI Characteristics

The 3300 XL transducer system utilizes eddy-current probe scaling to convert shaft motion into a linear voltage signal. During installation, gap voltage validation against -10 VDC targets at the oscillator interface is required to ensure the probe tip operates within the optimal linear measurement range. The system supports rotor dynamics analysis by maintaining signal linearity. Cross-talk suppression is maintained through frequency-coded oscillator channels, preventing signal interference between adjacent proximity sensors in high-density machine configurations.

Installation Guidelines

• Mechanical Mounting: Thread the probe into the mounting bracket; use a feeler gauge to verify the air gap matches design specifications for a -10 VDC gap voltage.

• Cabling: Route coaxial cabling through grounded metallic conduit to protect against electromagnetic interference; observe minimum cable bend radii.

• Grounding: Secure the probe body to the machine housing to establish a consistent electrical ground reference.

• Connection Check: Verify all coaxial connections are clean, hand-tightened, and free of moisture or particulates to ensure electrical integrity.

• Signal Validation: Perform a static gap voltage check using a high-impedance voltmeter at the oscillator output prior to machine startup.

Frequently Asked Questions

• Q: Is this probe compatible with standard 11 mm probe oscillators?

  A: No, this 8 mm probe must be paired with a matched 8 mm oscillator to maintain correct scaling and frequency response.

• Q: How is the probe gap validated?

  A: The gap is validated by measuring the output voltage at the oscillator terminals; the system target is -10 VDC at the nominal gap.

• Q: Can the coaxial cable be field-spliced?

  A: No, field-splicing modifies the electrical resonance and impedance of the transducer system, which invalidates the factory-calibrated scale factor.

• Q: What effect does the target material have on the output?

  A: Probe sensitivity is calibrated for 4140 steel; other materials require a scaling factor adjustment to ensure measurement accuracy.

• Q: What is the function of the connector protector cap?

  A: The cap prevents dust, oil, and environmental contaminants from entering the connector interface during installation.

• Q: Does the probe require an external power supply?

  A: No, the probe is a passive device; excitation power is supplied via the radio-frequency carrier generated by the oscillator.

• Q: What causes unstable or drifting signal readings?

  A: Instability is often caused by loose coaxial connections, electrical ground loops, or physical damage to the probe tip.

• Q: Should thread-locking compound be used during installation?

  A: No, thread-locking compounds may create an insulating barrier that disrupts the electrical ground path between the probe and machine casing.
