During installation, field technicians execute gap voltage validation (-10 VDC targets) across the non-isolated PROX OUT and COM terminals to ensure the matching 3300 NSv probe operates within its optimized linear zone. The system relies on high internal cross-talk suppression to isolate electrical noise induced by high-frequency rotor dynamics. If a physical disconnect or probe fault occurs, the integrated Not OK\/Signal Defeat circuit drops the loop current below 4-20 mA limits, disabling false vibration alarms in the machinery control system.\u003c\/p\u003e\n\u003ch3\u003ePackage Elements\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 990-10-XX-01-00 MOD 163930-01 Transmitter Module\u003c\/li\u003e\n\u003cli\u003e2 x Pre-fit 35
