To ensure measurement integrity, channel-to-channel isolation must be maintained within the input interface of the monitoring system to prevent ground loops that could introduce signal drift. While these components are passive, they require a compatible signal conditioner to manage the high-impedance voltage output. Cold junction compensation (CJC) is not applicable; however, maintaining impedance matching between the sensor coil and the signal interface is necessary to ensure the frequency response remains within the rated 4-1000 Hz window.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the explosion-proof rating (EEx ib) allow for installation in any hazardous area?\u003c\/p\u003e\n\u003cp\u003eA: The EEx ib rating restricts use to specific zones as defined by the regional hazardous area classification. Ensure that the associated apparatus (safety barrier) is properly matched to the sensor's electrical parameters before commissioning.\u003c\/p\u003e\n\u003cp\u003eQ: Is the sensor susceptible to vibration along the lateral axis?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The sensor is limited to a maximum lateral acceleration of 2 g. Mounting the sensor in an orientation that exceeds this limit, or allowing significant cross-axis vibration, will cause nonlinear output and mechanical degradation of the internal suspension.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eSecure the sensor to a machined, flat surface on the bearing housing or casing to ensure rigid high-frequency coupling and prevent resonance-induced noise.\u003c\/li\u003e\n\u003cli\u003eVerify the mounting orientation matches the sensor's internal suspension design; deviation from the horizontal or vertical axis will shift the natural frequency from the nominal 4.5 Hz.\u003c\/li\u003e\n\u003cli\u003eTerminate signal leads using shielded twisted-pair cabling; connect the shield to a single-point instrument ground at the control cabinet to mitigate electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eRoute signal lines through grounded metallic conduit, keeping them physically separated from high-current motor leads or power feeds to prevent inductive noise injection.\u003c\/li\u003e\n\u003cli\u003ePerform a physical bump test during initial setup to confirm the polarity of the output signal and ensure the signal path is clear before bringing the rotating machinery to full speed.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53036182143285,"sku":"PR9268\/201-100","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/PR9268301-100_b01fddbc-30a5-4c1d-b523-5798cba3b445.png?v=1782378051","url":"https:\/\/www.5gplc.com\/products\/pr9268-201-100-emerson-epro-electrodynamic-velocity-sensor","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
