The CON021 converter processes these impedance shifts into a standardized analog output (selectable 0-10 VDC or 4-20 mA). This linearization ensures that the electrical output remains strictly proportional to the physical gap distance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGap Voltage Validation:\u003c\/strong\u003e Successful installation requires precise calibration to the 2.7 mm nominal air gap. Validation of the gap voltage (typically targeting the converter's linear setpoint) ensures the system operates in the active zone of its dynamic range, preventing clipping or saturation during high-amplitude shaft oscillations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor Dynamics and Signal Processing:\u003c\/strong\u003e The assembly supports a bandwidth of 20 kHz, allowing for the detection of high-frequency vibration signatures. This wide frequency response is essential for monitoring turbine-generator sets, where fundamental rotation components (1X) and higher-order structural or bearing-related frequencies must be captured without attenuation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 10-meter integrated probe cable be cut or spliced to fit a shorter conduit?\u003c\/p\u003e\n\u003cp\u003eA: No. The cable is a calibrated part of the probe's resonant oscillator circuit. Any modification to the cable length alters the system's characteristic impedance and capacitance, which will induce a measurement error and invalidate the factory-specified 4 V\/mm sensitivity.\u003c\/p\u003e\n\u003cp\u003eQ: What is the impact of using a shaft diameter smaller than 80 mm?\u003c\/p\u003e\n\u003cp\u003eA: A shaft diameter of at least 80 mm is required for this probe geometry. Smaller diameters cause the magnetic flux lines to wrap around the shaft circumference, causing the probe to lose sensitivity and produce a non-linear signal that does not correspond to the actual displacement.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe Seating and Gap Setting:\u003c\/strong\u003e Thread the PR6424 probe into the bearing housing mount. Using a non-magnetic feeler gauge, establish the 2.7 mm nominal gap. Secure the locknuts against the mounting bracket to ensure the probe remains stationary during thermal expansion and transient machine vibration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShielding and Grounding:\u003c\/strong\u003e Terminate the signal leads at the CON021 converter using the provided screw terminals. The cable shield must be isolated at the probe end and grounded strictly at the instrumentation rack bulkhead. Do not route the signal cable parallel to high-power motor leads or AC phases, as this will induce common-mode noise into the measurement loop.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Emerson Epro","offers":[{"title":"Default Title","offer_id":45149653041267,"sku":"CON021+PR6424\/010-120","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-06-04_14-35-24_92be623c-f0ac-44e1-b802-91a971074680.png?v=1783046994","url":"https:\/\/www.dcssupplier.com\/ar\/products\/emerson-epro-con021-pr6424-010-120-current-displacement-system","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
