When integrated into industrial transmitter networks, the conditioned vibration or displacement signal utilizes a 4-20 mA HART loop protocol to transmit real-time shaft dynamics directly to DCS input cards. High channel-to-channel isolation safeguards the signal loop against ground potential differences across field wiring runs, ensuring stable data transmission from turbine bearings to control room enclosures.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the physical air gap set during mechanical installation?\u003c\/p\u003e\n\u003cp\u003eA: Thread the probe into the mounting frame until the initial air gap reaches approximately 0.5 mm (20 mils), corresponding to the baseline DC bias voltage specified by the connected signal converter card. Lock the mounting nut once this gap voltage is achieved.\u003c\/p\u003e\n\u003cp\u003eQ: Can the integral cable on the PR6423\/013-000-CN be modified or spliced in the field?\u003c\/p\u003e\n\u003cp\u003eA: No. Altering integral cable length changes total system inductance and capacitance, destroying factory tuning and causing deviations from the 8 V\/mm scale factor.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the PEEK sensing tip and threaded body for scratches, contamination, or thread galling prior to installation.\u003c\/li\u003e\n\u003cli\u003eConfirm the mounting bracket tapping is clean, burr-free, and correctly aligned with the shaft centerline.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum radial clearance of 15 mm surrounding the PEEK tip to prevent false loading from surrounding metal walls.\u003c\/li\u003e\n\u003cli\u003eCarefully thread the probe into position while measuring the live DC gap voltage at the signal converter terminals.\u003c\/li\u003e\n\u003cli\u003eOnce the required zero gap voltage is established, lock the outer jam nut to a maximum torque of 12 Nm without allowing the probe casing to rotate.\u003c\/li\u003e\n\u003cli\u003eRoute the triaxial cable through grounded conduit, isolated from high-voltage AC lines and variable frequency drive cables.\u003c\/li\u003e\n\u003cli\u003eConnect all wiring inside IP67-rated enclosures, terminating the cable shield drain wire at the monitoring rack frame end only.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Emerson Epro","offers":[{"title":"Default Title","offer_id":45510137577587,"sku":"PR6423\/013-000-CN","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/PR9268301-100_0f176e75-93ff-4d8b-9c07-252ebd37a960.png?v=1789630013","url":"https:\/\/www.dcssupplier.com\/products\/epro-pr6423-013-000-cn-current-proximity-sensors","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
