The internal oscillator conditions the high-frequency RF signal (ranging from 10 kHz to 1 MHz) transmitted through the 50 Ohm input line. Proper installation geometry maintains high eddy-current probe scaling accuracy (+\/- 0.5%) and establishes optimal cross-talk suppression between adjacent sensors monitoring complex rotor dynamics within the bearing housing.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can this 5\/8mm Proximitor sensor be used with a 25 mm large-scale displacement probe?\u003c\/p\u003e\n\u003cp\u003eA: No. The internal oscillator and linearization circuitry of the 144181-51 are calibrated for the specific impedance and sensitivity curves (7.87 V\/mm) of 5 mm and 8 mm probes. Connecting a 25 mm probe will disable correct scale factor tracking and induce severe measurement saturation.\u003c\/p\u003e\n\u003cp\u003eQ: What is the significance of the -17.5 VDC to -26 VDC input range?\u003c\/p\u003e\n\u003cp\u003eA: This specifies the acceptable DC power rail window supplied by the monitoring rack (such as a 3500 series instrument network). Clean power within this envelope is necessary to prevent scale drift and maintain the baseline 100 mV measurement resolution.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Isolation\u003c\/strong\u003e: Mount the sensor enclosure directly onto 35 mm DIN rail or a flat bulkhead panel.
