During installation, the probe must be positioned to allow for precise gap voltage validation against the standard -10 VDC targets. This housing assembly provides a stable mechanical platform that minimizes vibration-induced noise and ensures effective cross-talk suppression by isolating the probe signal from mechanical chassis resonance. Correct alignment within the assembly is required to maintain the accuracy of rotor dynamics data captured by the proximity transducer system.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 21000-16-05-15-098-03-02 Probe Housing Assembly\u003c\/li\u003e\n\u003cli\u003e1 x 3\/4-14 NPT Plug\u003c\/li\u003e\n\u003cli\u003e1 x 3\/4-14 to 1\/2-14 NPT Reducer\u003c\/li\u003e\n\u003cli\u003e1 x Cable seal grip assembly (including 3 sets of grommets for 1\/8-3\/16, 1\/4-5\/16, and 5\/16-3\/8 inch cable diameters)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProcess Connection: Ensure a minimum engagement of 5 full NPT threads when installing the housing into the machine port to maintain structural integrity and pressure containment.\u003c\/li\u003e\n\u003cli\u003eCable Sealing: Select the appropriate grommet from the provided kit to match the probe cable diameter.
