Hardware Specifications

Mechanical Monitoring & TSI Characteristics

The 3300 XL transducer system utilizes eddy-current probe scaling to convert shaft position data into a linearized voltage output. During commissioning, gap voltage validation against -10 VDC targets at the oscillator interface is required to ensure the probe tip remains within the specified linear measurement range. This system is designed for rotor dynamics monitoring where high-resolution displacement detection is required. Cross-talk suppression is achieved via frequency-coded oscillator channels, which prevent signal interference in high-density sensor arrays.

Installation Guidelines

• Mechanical Mounting: Thread the probe into the mounting bracket; use a feeler gauge to verify the physical air gap to achieve the -10 VDC operational target.

• Cabling: Route the coaxial cable through grounded metallic conduit; observe the specified minimum bend radius to avoid internal structural damage to the cable.

• Grounding: Establish a continuous ground path from the probe body to the machine housing to maintain a reliable signal reference.

• Connection Verification: Ensure all coaxial connectors are clean and hand-tightened prior to system finalization.

• Static Calibration: Confirm the static gap voltage with a high-impedance multimeter before engaging the monitoring system.

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 characteristics.

• Q: How is the correct probe gap validated?

  A: Measure the DC output voltage at the oscillator terminals with a high-impedance multimeter; the nominal target is -10 VDC within the linear operating range.

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

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

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

  A: Sensitivity is factory-calibrated for 4140 steel; usage with other materials necessitates a scaling factor adjustment to ensure measurement accuracy.

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

  A: The cap prevents moisture, dust, or grease from entering the coaxial connection, preserving electrical signal integrity.

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

  A: No, it is a passive device; excitation power is provided by the radio-frequency carrier signal generated by the 3300 XL oscillator.

• Q: What causes unstable or drifting signal readings?

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

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

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