To ensure accurate measurement, the eddy-current probe scaling must be verified against the specific magnetic permeability of the target shaft material, such as AISI 4140 steel. During installation, gap voltage validation—targeting the midpoint of the linear operating range—is required to ensure the sensor response remains within its operational limits. In multi-channel TSI systems, cross-talk suppression must be enforced by maintaining minimum physical separation between adjacent probe tips to prevent frequency interference in the oscillator circuits.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the integral 3-conductor shielded cable be shortened or extended in the field?\u003c\/p\u003e\n\u003cp\u003eA: The cable is a matched component of the inductive oscillator circuit. Modifying the cable length alters the circuit impedance and resonance frequency, which will induce significant measurement errors. Changes to cabling must only be executed using factory-approved matched extension cables.\u003c\/p\u003e\n\u003cp\u003eQ: What are the consequences of mounting the probe in non-ferrous material?\u003c\/p\u003e\n\u003cp\u003eA: Sensitivity is defined by the magnetic properties of the target. Non-ferrous materials exhibit different eddy-current damping characteristics, rendering the standard sensitivity of 8.0 mV\/um invalid. Recalibration or application of a specific material correction factor is required for non-ferrous targets.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the probe into a rigid bracket to prevent mechanical vibration of the probe body, which is indistinguishable from shaft displacement in the output signal.\u003c\/li\u003e\n\u003cli\u003eVerify the air gap using a calibrated feeler gauge to ensure the output voltage aligns with the nominal -10 VDC gap setting.\u003c\/li\u003e\n\u003cli\u003eTerminate the shield at the signal conditioner end to a common instrument ground; ensure the shield does not contact the machine casing to prevent ground loops.\u003c\/li\u003e\n\u003cli\u003eSeparate signal cabling from high-power AC or VFD cables to minimize electromagnetic noise coupling into the high-frequency probe circuit.\u003c\/li\u003e\n\u003cli\u003ePerform a commissioning verify at operational speed to ensure the output signal does not drift due to thermal expansion of the machine housing.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53036241944885,"sku":"PR6426\/010-140","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/PR937620_3856dac1-841d-45b6-a08a-8877d446a611.png?v=1782379048","url":"https:\/\/www.5gplc.com\/products\/pr6426-010-140-epro-eddy-current-sensor-eddy-current-signal-converter","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
