Hardware Specifications

Mechanical Monitoring and TSI Integration

This probe utilizes eddy-current transducer scaling to measure distance between the sensor tip and the conductive target. The system operates on a linear range defined by the target material, typically requiring a gap voltage validation target of -10 VDC when measured at the center of the linear span. Rotor dynamics analysis relies on the high-frequency response of this probe to detect vibration vectors. To ensure signal integrity, cross-talk suppression is maintained by utilizing shielded coaxial cabling, preventing electromagnetic interference from contaminating the radial vibration or thrust position signals processed by the monitoring modules.

Field Installation Guidelines

• Gap Setting: Use a feeler gauge to establish the cold-gap required for the specific machinery application.
• Grounding: Terminate cable shielding at the Proximitor sensor end to minimize ground loops.
• Bending Radius: Maintain a minimum bend radius of 25 mm for the miniature coaxial cable to prevent impedance shifts.
• Thread Engagement: Ensure full engagement of the M8 x 1 thread into the mounting bracket to prevent mechanical resonance.
• Connector Integrity: Ensure the ClickLoc connector is fully seated and clicked to maintain environmental sealing.

Frequently Asked Questions

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

  A: Yes, the probe tip is rated for continuous operation up to 177 deg C.

• Q: Does the cable length affect the system calibration?

  A: Yes, the total length of 1.0 meter is integrated into the system impedance and must not be altered in the field.

• Q: Is this probe compatible with older 3300 monitoring systems?

  A: The 3300 5mm probe is designed for compatibility with standard 3300 series Proximitor sensors.

• Q: What is the effect of changing the target material?

  A: Changing the target material from 4140 steel will significantly alter the probe scaling and linearity, requiring recalibration.

• Q: Why is the ClickLoc connector preferred?

  A: The ClickLoc connector ensures a vibration-proof mechanical connection that prevents intermittent electrical contact.

• Q: Can the probe be painted or coated?

  A: No, any coating on the probe tip will create a false gap and attenuate the eddy-current signal response.

• Q: What happens if the probe tip touches the rotating shaft?

  A: Physical contact can damage the probe tip and produce erroneous voltage spikes, potentially triggering an alarm in the monitor system.

• Q: How is the probe protected against moisture?

  A: The ClickLoc connector and probe case are designed to prevent moisture ingress, provided they are correctly installed and tightened.
