Eddy-Current Measurement and Rotor Dynamics
The probe operates as the sensing element of an eddy-current proximity transducer system. It detects changes in the electrical response between the probe tip and a conductive shaft target, allowing the connected monitor to derive shaft displacement.
For rotor-dynamic measurements, correct probe orientation and mechanical positioning directly affect the measured vibration waveform. Therefore, installers should maintain the specified probe-to-target relationship and avoid mechanical movement after installation.
The 5 mm probe format supports applications where a smaller sensing geometry suits the available machine installation space. The unarmored cable configuration also requires controlled routing to limit mechanical damage and unwanted signal coupling.
Frequently Asked Questions
Q: What thread does the 330173-00-06-10-02-00 use?

A: It provides a 1.0 meter, 75 ohm triaxial FEP-insulated cable with a miniature coaxial ClickLoc connector.
Q: What temperature range does the probe support?
A: The supplied specification lists an operating temperature range from -35 deg C to +177 deg C.
Field Installation Guidelines
- Install the probe with the M8 x 1 threaded body correctly aligned to the machine mounting point.
- Maintain the required probe-to-shaft target geometry specified by the associated transducer system documentation.
- Route the unarmored cable away from rotating components, sharp edges, excessive vibration, and high-current power conductors.
- Avoid tight bends, crushing, or mechanical loading at the cable-to-connector transition.
- Keep the triaxial signal cable separated from sources of electromagnetic interference where practical.
- Verify the connector is fully seated before commissioning the monitoring circuit.
- Check the probe case torque during installation and remain within the supplied 5.1 N m recommended and 7.3 N m maximum values.
- Confirm signal polarity, probe gap, and monitor channel configuration before placing the machinery protection circuit into service.
- For rotor-dynamic measurements, verify the installed probe location against the machine monitoring drawing and measurement direction.
