Hardware Specifications

Mechanical Monitoring & TSI Characteristics

The 3300 XL PROXPAC transducer utilizes eddy-current probe scaling to convert non-contacting shaft displacement into a linearized voltage output. During commissioning, gap voltage validation against -10 VDC targets is performed to confirm the probe operates within the linear range. The device facilitates rotor dynamics analysis by maintaining signal linearity across the air gap. Cross-talk suppression is maintained via internal frequency tuning, which prevents signal interference when multiple sensors are mounted in high-density machine configurations.

Field Installation Guidelines

• Mechanical Mounting: Install the transducer housing to a rigid machine surface; ensure the probe tip is secured at the required gap distance.

• Electrical Cabling: Connect the -24 VDC supply and signal output using shielded instrumentation cable; maintain strict polarity.

• Grounding: Bond the transducer case to the machine ground reference to ensure stable electrical operation.

• Signal Protection: Route all signal wiring through grounded rigid conduit to mitigate electromagnetic interference.

• Gap Verification: Use a high-impedance voltmeter to confirm the static gap voltage meets the -10 VDC target prior to machine rotation.

Frequently Asked Questions

• Q: Is the PROXPAC XL compatible with external Proximitors?

  A: No, the PROXPAC XL integrates the oscillator within the transducer housing, eliminating the need for a separate Proximitor unit.

• Q: Can the cable be field-modified?

  A: No, the cable length is calibrated to match the system resonance; any modification will invalidate the transducer scale factor.

• Q: How is signal integrity checked?

  A: Monitor the RF carrier signal with an oscilloscope or verify that the DC output voltage corresponds to the physical gap.

• Q: Does this unit support hot-swapping?

  A: The unit can be replaced, provided power is isolated beforehand to prevent electrical faults during disconnection.

• Q: What is the maximum signal output distance?

  A: Signal transmission can achieve up to 300 meters using appropriate low-capacitance, shielded instrumentation cable.

• Q: Is this device compatible with third-party monitoring systems?

  A: Compatibility depends on the system's ability to accept a -24 VDC powered, standard proximity voltage output signal.

• Q: Why is a 3.07 m length specified?

  A: This is the factory-set resonant length required to maintain the specified electrical sensitivity and frequency response.

• Q: How is ground loop noise mitigated?

  A: The system employs a single-point ground connection via the transducer housing to prevent noise injection.
