    FAQs

    Q1: What is the function of the 330854-040-25-CN in a 3300 XL system?

    It connects a 3300 XL 25 mm proximity probe to a compatible Proximitor sensor, transmitting the eddy-current displacement signal for differential expansion, thrust position, and large shaft displacement measurements. The extension cable is part of the calibrated electrical length of the system, ensuring accurate signal transmission without degradation.

    Q2: What does the "-CN" suffix indicate?

    The "-CN" suffix indicates that the cable is certified for the Chinese market, meeting specific national standards (NEPSI/CCC) required for legal installation and operation within mainland China facilities.

    Q3: What is the 3300 XL 25 mm system used for?

    The 25 mm system provides the longest linear range in the 3300 XL family (up to 12.7 mm or 500 mils), making it ideal for measuring large axial movements such as differential expansion on large steam turbines and generators. It is also used for thrust position and other applications where standard 8mm or 11mm systems lack sufficient measurement span.

    Q4: How do I ensure proper system compatibility?

    The total electrical length of the probe cable plus this extension cable must equal the rated system length of the Proximitor sensor. For this 4.0m cable, you would typically pair it with a 1.0m probe and a 5.0m Proximitor sensor. All 3300 XL 25 mm system components are fully interchangeable without bench calibration.

    Q5: Is the 330854-040-25-CN compatible with 8mm or 11mm systems?

    No. The 330854-040-25-CN is part of the 3300 XL 25 mm system and is not compatible with 8mm or 11mm probes, extension cables, or Proximitors. The 25 mm system uses different connectors, cable lengths, and Proximitor sensitivity settings. Always verify the complete transducer chain is from the same system family.
