Proper application requires that the probe tip remains centered relative to the target to maintain the validity of -10 VDC gap voltage targets. The assembly facilitates stable rotor dynamics monitoring by providing rigid support, thereby preventing signal noise induced by mechanical oscillation of the mounting interface. Cross-talk suppression is maintained by ensuring proper orientation during the final tightening of the NPT process connection.\u003c\/p\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 21000-00-00-15-085-03-02 Housing Assembly\u003c\/li\u003e\n\u003cli\u003e1 3\/4-14 NPT plug\u003c\/li\u003e\n\u003cli\u003e1 3\/4-14 to 1\/2-14 NPT reducer\u003c\/li\u003e\n\u003cli\u003e1 Cable seal grip with associated grommets (1\/8 to 3\/8 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Procedures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProcess Connection: Thread the 3\/4-14 NPT base into the machine casing using an approved pipe sealant to prevent fluid leakage.\u003c\/li\u003e\n\u003cli\u003eCable Sealing: Select the appropriate grommet size from the included kit to ensure the cable grip provides a liquid-tight seal around the coaxial cable jacket.\u003c\/li\u003e\n\u003cli\u003eStructural Integrity: Ensure the assembly is tightened to prevent loosening from machine vibration.
