Probes must be installed with consideration for target material permeability (AISI 4140 standard); non-standard target materials require recalibration of the CON031 output linearization curve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGap voltage validation (-10 VDC targets):\u003c\/strong\u003e During installation, the static gap voltage must be verified using a high-impedance digital multimeter. Targets are typically set at the center of the 1.0 mm linear range to maintain symmetrical dynamic vibration monitoring capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor dynamics:\u003c\/strong\u003e The system frequency bandwidth (DC to 10 kHz) supports both slow-roll shaft position observation and high-frequency dynamic vibration analysis. Signal processing in the CON031 ensures that phase shift remains within tolerance for transient event capture during machine run-up or coast-down.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-talk suppression:\u003c\/strong\u003e To maintain signal integrity, maintain a minimum spacing of 3 probe diameters between adjacent sensors. If physical constraints prevent this, probes must be oriented to prevent electromagnetic field overlap, which manifests as additive noise in the output signal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the CON031 signal converter be used with a different probe series?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the CON031 is compatible with the PR6422, PR6423, PR6424, and PR6426 series. However, the system must be recalibrated for the specific measurement range (1 mm, 2 mm, 4 mm, or 12 mm) to maintain linearity specifications.\u003c\/p\u003e\n\u003cp\u003eQ: How does the system handle rapid temperature fluctuations at the measurement tip?\u003c\/p\u003e\n\u003cp\u003eA: The probe assembly utilizes PEEK polymer tips and high-temperature PTFE cabling. Temperature drift is constrained to less than 0.05% per deg C, ensuring that thermal growth of the machine casing does not result in false alarms or erroneous displacement readings.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Ensure the sensor housing is secured using the provided locking nuts. The probe tip must be recessed or extended to achieve the recommended 0.25–0.5 mm air gap relative to the shaft surface at nominal machine operating temperature.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShielding:\u003c\/strong\u003e Route the integrated 1 m coaxial cable through grounded metallic conduit to protect against electromagnetic interference. Avoid sharp bends in the cable, as mechanical stress can alter the cable impedance and introduce signal errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding:\u003c\/strong\u003e Connect the CON031 signal ground to the common instrument earth bus. Ensure that the probe tip does not contact the shaft during operation, as this will damage the PEEK tip and cause a short-to-ground fault in the eddy-current drive circuit.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Emerson Epro","offers":[{"title":"Default Title","offer_id":45164831244403,"sku":"CON031+PR6424\/000-121","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-06-10_16-05-55_a8548ac6-b6bc-46c0-ae91-54057c62df37.png?v=1783332570","url":"https:\/\/www.dcssupplier.com\/ar\/products\/emerson-epro-con031-pr6424-000-121-proximity-measurement-system","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
