When interfaced into DCS platforms operating 4-20 mA HART loop protocol transmitters or FOUNDATION Fieldbus signal interface gateways, the transducer loop maintains high frequency linearity. Thermal compensation circuitry provides cold junction compensation tracking to stabilize measurement accuracy during environmental temperature shifts across the -35 to +180 deg C operational limits.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the extended thermal exposure limits for the PR6423\/00N-030 sensor head?\u003c\/p\u003e\n\u003cp\u003eA: The sensor supports continuous operation from -35 to +180 deg C (-31 to 356 deg F) and can tolerate short-term thermal excursions up to +200 deg C (392 deg F) for periods up to 5 hours.\u003c\/p\u003e\n\u003cp\u003eQ: How does non-contact eddy current sensing function in shaft displacement monitoring?\u003c\/p\u003e\n\u003cp\u003eA: The probe generates a high-frequency electromagnetic field at the tip; physical target movements alter eddy current losses, producing a proportional voltage change evaluated by downstream signal converters.\u003c\/p\u003e\n\u003cp\u003eQ: Does the sensor require external power directly at the probe head?\u003c\/p\u003e\n\u003cp\u003eA: No, the passive inductive transducer head is driven and powered directly via coaxial connection from an external signal converter module.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the target shaft region to verify surface finish is free from scratch defects, mechanical runout, and residual magnetism.\u003c\/li\u003e\n\u003cli\u003eMount the PR6423 probe head into its machine casing bracket perpendicular to the rotating shaft centerline.\u003c\/li\u003e\n\u003cli\u003eAdjust the static air gap using non-magnetic shims or by measuring static output bias voltage prior to securing the housing.\u003c\/li\u003e\n\u003cli\u003eTorque the outer mounting locknut against the bracket to prevent physical displacement caused by operational machine vibration.\u003c\/li\u003e\n\u003cli\u003eRoute the integral transducer cable through grounded rigid or flexible metallic conduit away from high-voltage motor wiring.\u003c\/li\u003e\n\u003cli\u003eConnect the outer cable shield to the single-point instrument ground bus inside the field termination enclosure.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53446354174261,"sku":"PR6423\/00N-030","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/CON031_PR642300R-101_f9ade9f1-c48b-4bbb-8fdb-8bbd7519b63e.png?v=1788343364","url":"https:\/\/www.5gplc.com\/products\/emerson-pr6423-00n-030-epro-eddy-current-displacement-transducers","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
