When integrated into control networks featuring 4-20 mA HART loop protocol transmitters or FOUNDATION Fieldbus monitoring nodes, the sensor system preserves linearity across dynamic vibration profiles. Thermal variations within the -35 to +180 deg C range are offset by cold junction compensation reference tracking within the evaluation converter to maintain sensitivity stability.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What target material is required to maintain the specified 8 V\/mm sensitivity without recalibration?\u003c\/p\u003e\n\u003cp\u003eA: The sensor sensitivity of 8 V\/mm is calibrated specifically for ferromagnetic steel targets; non-magnetic or alternative alloy targets alter inductive coupling and require re-scaling.\u003c\/p\u003e\n\u003cp\u003eQ: How does the IP66 rating and pressure resistance limit environmental ingress at the installation point?\u003c\/p\u003e\n\u003cp\u003eA: The sensor body features an IP66 ingress protection rating against heavy fluid spray and resists static process casing pressures up to 10000 hPa (145 psi).\u003c\/p\u003e\n\u003cp\u003eQ: What is the mechanical function of the PTFE cable sheath?\u003c\/p\u003e\n\u003cp\u003eA: The PTFE cable material provides high thermal tolerance up to +180 deg C and Chemical resistance against synthetic lubricants inside turbomachinery housings.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eClean the rotor measurement surface to ensure it is free from metal debris, mechanical gouges, and excessive surface runout.\u003c\/li\u003e\n\u003cli\u003eThread the 100 mm casing of the probe into the mounting bracket perpendicular to the target shaft axis.\u003c\/li\u003e\n\u003cli\u003eSet the mechanical air gap using non-magnetic feeler gauges or by monitoring static DC bias voltage at the evaluation unit before locking.\u003c\/li\u003e\n\u003cli\u003eTorque the outer mounting jam nut against the bracket to prevent mechanical loosening under operational vibration.\u003c\/li\u003e\n\u003cli\u003eRoute the PTFE cable through protective grounded conduit, maintaining minimum bend radii to protect internal coaxial conductors.\u003c\/li\u003e\n\u003cli\u003eConnect the cable shield to the single-point instrument ground bus inside the junction enclosure.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53446298075445,"sku":"PR6423\/010-100","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/PR6423002-041_8fef96b1-6e93-4238-ae39-5201669a3f1e.png?v=1788342514","url":"https:\/\/www.5gplc.com\/products\/pr6423-010-100-epro-eddy-current-displacement-sensors-emerson","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
