Hardware Specifications

Mechanical Monitoring & TSI Characteristics

The 3300 XL 8 mm transducer system utilizes an eddy-current principle to measure the distance between the probe tip and a conductive surface. System performance is optimized through precise rotor dynamics scaling, ensuring that the Proximitor sensor output maintains a linear relationship with the gap. To ensure signal integrity, the -10 VDC gap voltage target must be validated during commissioning. The system is designed for cross-talk suppression by utilizing specific frequency modulation, allowing for high-accuracy vibration measurement without interference from adjacent probe installations. Adherence to API 670 standards ensures that the probe, extension cable, and Proximitor sensor remain fully interchangeable, requiring no additional bench calibration after replacement.

Frequently Asked Questions

Q: Can the 330103 probe be used with non-XL series extension cables?

A: While the 3300 XL system is designed for backward compatibility with older non-XL components, it is recommended to use the complete 3300 XL transducer system (probe, cable, and sensor) to achieve the performance specifications defined by the API 670 standard.

Q: What is the impact of incorrect gap voltage on the system output?

A: The Proximitor sensor output is directly proportional to the gap between the probe and the target. A gap voltage deviation from the -10 VDC target will introduce linear measurement errors, directly affecting the accuracy of both static position and dynamic vibration readings.

Field Installation Guidelines

• Ensure the probe mounting location is free of debris to prevent false signal attenuation.
• Use appropriate thread-locking compounds if required by the mechanical installation manual, ensuring electrical grounding through the probe housing is not compromised.
• The probe tip must not touch the target surface during operation; verify the required gap distance prior to fixing the locknut.
• Route the coaxial cable within a grounded conduit to protect against electromagnetic interference and physical mechanical damage.
• Check all connectors for firm engagement and ensure they are clean and dry before applying system power to the Proximitor sensor.
