The 12mm tip produces a larger electromagnetic field, allowing the sensor to maintain high linearity over a 4mm span. This is crucial for tracking thermal growth in turbine rotors to prevent catastrophic contact between rotating and stationary components. The stainless steel armor provides essential mechanical protection for the coaxial cable within the harsh, oil-saturated environment of bearing housings, ensuring signal integrity over years of continuous operation.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"12\"\u003eFAQs\u003c\/h3\u003e\n\u003cul data-path-to-node=\"13\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,0,0\"\u003e\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eWhy does this sensor use a 12mm tip instead of the standard 8mm?\u003c\/b\u003e The 12mm tip is necessary to achieve the 4mm linear range. Standard 8mm sensors (like the PR6423) are generally limited to a 2mm range, which is often insufficient for monitoring axial thrust or differential expansion in large turbines.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,1,0\"\u003e\u003cb data-path-to-node=\"13,1,0\" data-index-in-node=\"0\"\u003eCan I connect this 1.0m sensor directly to my monitor?\u003c\/b\u003e The 1.0m cable is a \"pigtail\" designed to exit the machine case. You must use a matching extension cable (usually 4m or 9m) to reach the total system length required by your specific driver or transmitter.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,2,0\"\u003e\u003cb data-path-to-node=\"13,2,0\" data-index-in-node=\"0\"\u003eWhat happens if the target material is not AISI 4140 steel?\u003c\/b\u003e Eddy current sensors are material-sensitive. If your shaft uses a different alloy, the output voltage will deviate from the standard calibration. In such cases, the driver must be recalibrated to match the specific metallic properties of your target.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13,3,0\"\u003e\u003cb data-path-to-node=\"13,3,0\" data-index-in-node=\"0\"\u003eHow do I ensure the sensor is mounted correctly?\u003c\/b\u003e Use a rigid mounting bracket and ensure the M14 threads are securely locked. Any movement in the sensor mounting itself will be incorrectly interpreted as shaft vibration, leading to false alarms in the protection system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":46632464679102,"sku":"PR6424\/010-100","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/emerson-pr6424-00-010-epro-plc-module-ccfak45loet.png?v=1773212951","url":"https:\/\/www.autooiltech.com\/products\/emerson-epro-pr6424-010-100-eddy-current-displacement-sensor","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
