The 330101 series utilizes an eddy-current principle to detect the proximity of a conductive target. Proper scaling is required to maintain the standard 7.87 V/mm (200 mV/mil) output sensitivity provided by the matching 3300 XL Proximitor sensor. During installation, the gap voltage must be validated against a -10 VDC target at the mid-linear range to ensure linear response. Signal integrity depends on minimizing cross-talk between adjacent probes and ensuring the target material surface conforms to material correction specifications to maintain accurate rotor dynamic vibration data.
Q: Can the 1.0 meter cable length be extended?
A: The total system length (probe + extension cable) must be matched to the Proximitor sensor calibration (typically 5 m or 9 m). If the probe cable is 1.0 m, an appropriate 4.0 m extension cable is required to reach a 5.0 m system length.
Q: What is the requirement for the thread engagement during installation?
A: A minimum of 4 to 5 threads of engagement is required for the probe housing to ensure mechanical stability and proper grounding in the machinery casing.
