Hardware Specifications

Mechanical Monitoring & Signal Dynamics

The 3300 XL sensor architecture utilizes precise eddy-current probe scaling to ensure linear response to target movement. For valid rotor dynamics data, the installation must maintain a nominal gap voltage of -10 VDC at the monitor input. Cross-talk suppression is maintained by matching the probe tip geometry and oscillation frequency, preventing interference from neighboring sensors in high-density installations. Signal fidelity is dependent on maintaining a continuous coaxial path and minimizing electromagnetic coupling along the cable run.

Field Installation Guidelines

• Gap Positioning: Set the probe tip at 1.27 mm from the target surface during cold static conditions.

• Torque Limits: Apply a maximum torque of 5.6 N-m to the probe locknut to secure the mounting bracket.

• Cable Handling: Maintain a minimum 25 mm bend radius; avoid mechanical stress on the ClickLoc connector interface.

• Grounding: Terminate the cable shield only at the monitor barrier end to avoid ground loop current paths.

Frequently Asked Questions

• Can this probe be used for high-temperature applications?

  The probe is rated for operation up to 177 deg C, suitable for standard turbine and compressor housing environments.

• What is the impact of changing the total length?

  System calibration is fixed to the 0.5 meter length. Deviating from this length will introduce phase and amplitude errors.

• Is the probe tip sensitive to oil immersion?

  The PPS tip is chemically inert and designed to operate fully submerged in industrial lubricating oils and hydraulic fluids.

• How is the linear range defined?

  The linear range is defined as 0.25 mm to 2.29 mm, where the output voltage scales linearly with the distance from the target.

• Does this model support hot-swapping?

  The probe itself is a passive sensor, but disconnecting it from an active Proximitor will cause a signal fault on the monitor card.

• What is the function of the 0 mm unthreaded length?

  This indicates a smooth-case probe design where the casing is not intended for threading into a machine bearing or housing.

• Can I use a non-Bently extension cable?

  Using non-specified cables will degrade the impedance matching, potentially causing signal drift and failure to meet accuracy requirements.

• How often should I check the gap voltage?

  Gap voltage should be verified during initial installation and following any mechanical maintenance performed on the target rotor.
