Hardware Specifications

Mechanical Monitoring & TSI Integration

This probe utilizes eddy-current probe scaling to convert target distance into an output voltage. System integration requires precise gap voltage validation, targeting -10 VDC at the monitor input when the probe is at the nominal gap. The transducer system relies on consistent rotor dynamics data, where cross-talk suppression is achieved through controlled coaxial cable impedance and proper shielding. The 8 mm tip provides a linear measurement range suitable for monitoring shaft vibration and axial position.

Field Installation Guidelines

• Mechanical Installation

• Thread the probe into the mounting bracket, ensuring at least 5 full NPT or metric thread engagements.

• Use locking nuts to secure the probe position after achieving the target gap voltage.

• Electrical Termination

• Ensure coaxial connectors are free of contaminants before mating to prevent signal noise.

• Route probe cabling through dedicated rigid conduit to protect against mechanical fatigue.

• Grounding

• The probe housing must maintain electrical continuity with the machine case to ensure proper system shielding.

Frequently Asked Questions

• Can this probe be used as a standalone sensor?

  No. This probe is a component of a 3300 XL transducer system and must be connected to a matching proximity extension cable and Proximitor sensor.

• How do I calibrate the probe gap?

  Adjust the probe position while monitoring the DC gap voltage at the monitor/BNC output until the required -10 VDC is achieved.

• Is the cable length field-adjustable?

  No. The cable length is fixed and calibrated to the system. Changing the length will alter the resonant frequency and system impedance.

• Can the probe tip be exposed to high pressure?

  The probe tip is rated for high-pressure oil/fluid exposure, but ensure the housing seal is installed correctly to prevent leakage at the mounting point.

• What is the frequency range of this probe?

  The probe system is designed to provide a linear response from 0 Hz (static) to 10 kHz (dynamic vibration).

• Does the probe support hot-swapping?

  No. Replacing the probe requires system isolation, as disconnecting the transducer will trigger a sensor fault signal in the monitor.

• How does the cable shield impact performance?

  The shield prevents external electrical interference. Ensure the shield integrity is maintained from the probe head to the monitor terminal.

• What is the impact of probe misalignment?

  Misalignment relative to the target surface center can reduce measurement linearity and impact the accuracy of vibration amplitude readings.
