The larger 12mm tip creates a more robust electromagnetic field, allowing for a 4mm linear measurement span. This capability is essential for tracking \"axial float\" and thermal expansion in massive steam turbines and compressors. Its armored cable provides superior mechanical protection against sharp edges and vibration wear within bearing pedestals. By delivering sub-micron resolution without physical contact, the sensor ensures zero mechanical wear and long-term stability in high-temperature, oil-saturated conditions.\u003c\/p\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhy should I choose the PR6424\/01 over an 8mm sensor?\u003c\/strong\u003eThe PR6424\/01 offers an extended linear range of 4mm.

The PR6424\/01 must be connected to an epro signal converter or driver (such as the CON 021 or MMS 6000 series) that is specifically calibrated for 12mm sensors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCan the armored cable be shortened?\u003c\/strong\u003eNo. Never cut or shorten the integrated cable. Eddy current measurement systems are electrically tuned to a specific total length.
