Variations in target proximity modulate this field, which the driver's internal demodulator circuitry translates into a standardized analog voltage loop proportional to shaft displacement parameters.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eModel\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003ePR9350\/02-S2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003eEmerson (EPRO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003eOrigin\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003eWeight\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003e0.55 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"6\"\u003eDimensions\u003c\/td\u003e\n\u003ctd data-row=\"6\"\u003e4.1 cm x 15.9 cm x 10.8 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"7\"\u003eOperating Temp\u003c\/td\u003e\n\u003ctd data-row=\"7\"\u003e-25 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"8\"\u003ePower Consumption\u003c\/td\u003e\n\u003ctd data-row=\"8\"\u003e24 VDC nominal (18-30 VDC input range), max. 50 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"9\"\u003eInput Interface\u003c\/td\u003e\n\u003ctd data-row=\"9\"\u003eModulated sensor signal from PR642x series probes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"10\"\u003eOutput Signal\u003c\/td\u003e\n\u003ctd data-row=\"10\"\u003eStandardized voltage (-2 VDC to -18 VDC proportional to gap)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"11\"\u003eScale Factor\u003c\/td\u003e\n\u003ctd data-row=\"11\"\u003e8 V\/mm (203.2 mV\/mil) +\/-5% (subject to S2 adjusted calibration)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"12\"\u003eLinear Measurement Range\u003c\/td\u003e\n\u003ctd data-row=\"12\"\u003e2 mm (80 mils) typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"13\"\u003eLinearity Deviation (DSL)\u003c\/td\u003e\n\u003ctd data-row=\"13\"\u003e+\/-0.025 mm (+\/-1 mil)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"14\"\u003eFrequency Response\u003c\/td\u003e\n\u003ctd data-row=\"14\"\u003eUp to 10 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"15\"\u003eProtection Class\u003c\/td\u003e\n\u003ctd data-row=\"15\"\u003eIP20 (module housing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"16\"\u003eMounting Options\u003c\/td\u003e\n\u003ctd data-row=\"16\"\u003eDIN rail or rack installation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"17\"\u003eCompliance\u003c\/td\u003e\n\u003ctd data-row=\"17\"\u003eAPI 670 compliant, CE marked\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eEddy-Current Probe Scaling and Gap Voltage Validation\u003c\/h3\u003e\n\u003cp\u003eVerification of the PR9350\/02-S2 operational envelope requires precise control over eddy-current probe scaling metrics to maintain the nominal factor of 8 V\/mm or specified S2 custom calibrations. During initial loop commissioning, field personnel execute a static gap voltage validation routing targeting a baseline parameter of -10 VDC at the driver terminal block under stationary conditions. This electrical calibration matches the target machinery shaft face with the geometric midpoint of the 2 mm linear measurement window. Proper mechanical offset alignment enables the internal circuitry to process real-time rotor dynamics without introducing asymmetric signal saturation, while preserving channel-to-channel cross-talk suppression inside the turbomachinery bearing cap.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What technical attributes differentiate the S2 variant from standard PR9350 drivers?\u003c\/p\u003e\n\u003cp\u003eA: The S2 suffix designates a factory-implemented configuration profile providing adapted output scaling, specific calibration values, or custom installation adjustments. The core electronic components maintain standard 10 kHz response attributes while accommodating non-standard machine target variables or alternative input scopes.\u003c\/p\u003e\n\u003cp\u003eQ: Does the PR9350\/02-S2 support online hot-swap insertion within an active monitoring rack?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the IP20 hardware chassis can be mounted to or detached from an energized 35 mm DIN rail segment. However, breaking the active transducer connection immediately interrupts the sensor excitation loop, causing the connected monitoring card to register an API 670 circuit fault and defeat active machinery protection logic.\u003c\/p\u003e\n\u003cp\u003eQ: What output behavior does the driver manifest during an unmitigated short-circuit condition on the probe side?\u003c\/p\u003e\n\u003cp\u003eA: A short-circuit across the transducer input terminals drops the oscillator tank voltage. The internal demodulator drives the continuous output voltage to a near-zero or positive saturation threshold outside the normal -2 VDC to -18 VDC span, indicating a circuit failure status to the host AMS 6500 rack.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Rail Alignment:\u003c\/strong\u003e Clamp the IP20 module chassis onto a grounded 35 mm DIN rail bracket.
