Hardware Specifications

TSI Mechanical Monitoring Characteristics

The system utilizes eddy-current probe scaling to convert shaft displacement into high-frequency carrier modulation. During commissioning, gap voltage validation against -10 VDC targets is required to ensure the probe tip is maintained within the linear operating range relative to the target surface. The integration of high-precision oscillators allows for consistent rotor dynamics monitoring, where accurate tracking of radial and axial movement is required. Cross-talk suppression between channels is achieved through specific oscillation frequencies assigned to adjacent probe systems, preventing signal interference in multi-probe monitoring arrays.

Field Installation Guidelines

• Mounting: Install the proximity probe into the designated mechanical housing; ensure the probe tip is set to the correct physical gap distance using a feeler gauge.

• Cabling: Route coaxial cabling through grounded metallic conduit to prevent signal noise; avoid sharp bends that exceed the minimum bend radius of the coaxial cable.

• Connector Integrity: Ensure all coaxial connectors are tightened to the specified torque and are clean of debris to maintain low-impedance electrical contact.

• Grounding: Bond the transducer system housing to the machine frame to provide a consistent electrical reference point for the eddy-current field.

• Calibration: Perform a static gap check to confirm that the transducer output voltage corresponds to the physical air gap measurement before system startup.

Frequently Asked Questions

• Q: Is the 31000 system compatible with 3300 XL monitoring racks?

  A: The 31000 series is a legacy transducer system; direct compatibility with 3300 XL monitors requires verification of signal matching and oscillation frequency compatibility.

• Q: How do I verify the probe is functioning correctly?

  A: Use a high-impedance digital voltmeter to measure the gap voltage at the monitor or oscillator; a steady voltage indicates the probe is sensing the target.

• Q: What is the maximum cable length allowed for this system?

  A: The total system length, including the probe and extension cable, must match the calibration of the oscillator; refer to the part number suffix for defined system length.

• Q: Can the probe withstand high-temperature environments?

  A: Yes, the probe and cable materials are rated for specific high-temperature limits; ensure the installation environment does not exceed the specified rating.

• Q: How does mechanical runout affect the measurement?

  A: Mechanical and electrical runout can induce false vibration readings; it is recommended to compensate for runout during initial baseline data acquisition.

• Q: Should I use PTFE tape on the probe threads?

  A: Avoid using excessive sealant on probe threads as it may compromise the electrical grounding between the probe body and the machine housing.

• Q: Does the probe require an external oscillator?

  A: Yes, this transducer system requires an oscillator to generate the radio-frequency field necessary for eddy-current displacement sensing.

• Q: How can I prevent moisture ingress in the connectors?

  A: Ensure that connector protectors are installed and that cables are routed to prevent water accumulation at the junction points.
