When routed into system transmitters, the output maps to a standard 4-20 mA HART loop protocol to transmit peak-to-peak shaft vibration amplitudes or static thrust positions to the DCS backplane. The transmitter incorporates channel-to-channel isolation to suppress ground loop currents across field wiring paths, while maintaining loop integrity during dynamic signal acquisition over extended field cable distances.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the physical gap voltage verified during mechanical positioning?\u003c\/p\u003e\n\u003cp\u003eA: Thread the sensor head into the mounting bracket while measuring the DC bias voltage across the output terminals of the CON021 module. Adjust probe insertion depth until the static DC reading hits the system zero reference point (typically -10 VDC), then secure the jam nut.\u003c\/p\u003e\n\u003cp\u003eQ: Can the integral triaxial cable between the probe tip and the CON021 driver be trimmed in the field?\u003c\/p\u003e\n\u003cp\u003eA: No. Altering the integral cable length changes total system inductance and capacitance, destroying factory tuning and rendering the output voltage calibration inaccurate.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the PEEK sensing tip and threaded stainless steel body for mechanical abrasions, metal particles, or thread damage prior to insertion.\u003c\/li\u003e\n\u003cli\u003eConfirm that the mounting bracket tapping is clean and free of metal burrs matching the thread pitch of the probe casing.\u003c\/li\u003e\n\u003cli\u003eEnsure a minimum radial clearance of 15 mm around the PEEK tip to prevent false side-loading effects from adjacent metal structures.\u003c\/li\u003e\n\u003cli\u003eCarefully thread the probe into position, observing real-time DC voltage readings on the driver terminal block during manual positioning.\u003c\/li\u003e\n\u003cli\u003eLock the outer jam nut to a maximum torque of 12 Nm once the target static DC gap voltage is achieved, ensuring the sensor body does not rotate during tightening.\u003c\/li\u003e\n\u003cli\u003eRoute the integral triaxial cable through dedicated metal conduit, isolating it from high-voltage motor power leads and variable frequency drive outputs.\u003c\/li\u003e\n\u003cli\u003eTerminate all wiring inside IP67-rated junction boxes, grounding the cable shield drain wire at the rack frame end only.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Emerson Epro","offers":[{"title":"Default Title","offer_id":45510131155059,"sku":"PR6423\/014-110","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/CON021_PR6423002-001-CN_1_c48a5c9a-1a6a-44c2-bcd1-f8c7ce509482.jpg?v=1789630090","url":"https:\/\/www.dcssupplier.com\/products\/pr6423-014-110-emerson-proximity-sensor","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
