Hardware Specifications

Mechanical Monitoring and Transducer Dynamics

The 330101 transducer relies on precise eddy-current probe scaling to ensure linear voltage output relative to the target gap. During installation, technicians must perform gap voltage validation to target -10 VDC at the center of the linear operating range. Effective cross-talk suppression is achieved by maintaining specified spacing between adjacent probes, preventing interference within the eddy-field. Accurate rotor dynamics analysis depends on maintaining this signal integrity and avoiding the influence of external magnetic noise on the transducer’s high-frequency carrier signal.

Field Installation Guidelines

• Target Surface: Confirm the observed shaft material is AISI 4140 steel for factory-calibrated output accuracy.

• Proximity Clearance: Maintain a minimum side-view clearance of 1.5 inches (38 mm) from the probe tip to prevent signal distortion from mounting hole walls.

• Probe Separation: Ensure a minimum of 1.5 inches (38 mm) between probe tips to suppress electromagnetic coupling and measurement errors.

• Connector Integrity: Verify the ClickLoc connection is fully seated and the cable is protected from excessive bending to maintain characteristic impedance.

Frequently Asked Questions

• Can this probe be used in hazardous locations?

  This specific model (Agency Approval 00) is not rated for hazardous area use. Verify the installation environment requirements before deployment.

• What is the impact of a non-standard cable length?

  The probe and cable are a matched system. Changing the cable length alters the system impedance, which causes measurement errors and invalidates the factory calibration.

• How is the probe tip protected from fluid ingress?

  The probe tip is sealed with high-performance synthetic materials. However, the connection point requires protection from direct exposure to chemical or process fluids.

• Can I repair a damaged probe cable?

  Field repair of the coaxial cable is not recommended as it compromises the signal integrity and impedance matching of the transducer system.

• What is the linear range of this probe?

  The 3300 XL 8 mm system typically provides a linear range of 80 mils (2 mm), beginning at approximately 10 mils from the target surface.

• Does the probe require external power?

  The probe is a passive transducer. It receives power from the associated Proximitor sensor through the coaxial cable connection.

• How is the probe held in place?

  The probe is secured using the provided 3/8-24 UNF threaded mounting nut, which should be torqued to ensure stable positioning during vibration.

• What defines the "unthreaded length"?

  The unthreaded length is the portion of the probe case near the tip without threads, allowing for mounting configurations that require a smooth probe body.
