This measurement is critical in steam turbines and other large rotating machinery where thermal growth can cause mechanical interference. The monitor continuously compares expansion values against alarm setpoints, providing early warning of abnormal conditions and protecting equipment from damage.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMeasures differential expansion between rotor and casing\u003c\/li\u003e\n\u003cli\u003eContinuous parameter comparison against alarm setpoints\u003c\/li\u003e\n\u003cli\u003eRelay actuation for Alert and Danger conditions\u003c\/li\u003e\n\u003cli\u003eLED indicators for OK, Bypass, Alert, and Danger status\u003c\/li\u003e\n\u003cli\u003eCompatible with standard proximity probe inputs via Proximitor sensors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e3300\/46-XX-XX-01-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eBently Nevada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e3300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e1.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e200 mV\/mil (8 V\/mm) or 100 mV\/mil (4 V\/mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/- 0.33% typical, +\/- 1% max at 25 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signals\u003c\/td\u003e\n\u003ctd\u003e+4 to +20 mA, +1 to +5 VDC, 0 to -10 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the 3300 rack is properly grounded to a clean earth point to minimize electrical noise.\u003c\/li\u003e\n\u003cli\u003eAlways power down the rack before inserting or removing the monitor module to prevent damage to the backplane connectors.\u003c\/li\u003e\n\u003cli\u003eUse shielded cables for all transducer inputs to protect against EMI in industrial environments.\u003c\/li\u003e\n\u003cli\u003eVerify that the probe configuration matches the specific module suffix settings for accurate measurement.\u003c\/li\u003e\n\u003cli\u003eEnsure adequate ventilation within the cabinet to maintain the operating temperature range of 0 to 60 degC.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the 3300\/46 monitor?\u003c\/h3\u003e\u003cp\u003eThis module is designed to monitor the differential expansion between the rotor and the casing of rotating machinery, such as steam turbines, to prevent mechanical interference caused by thermal growth.\u003c\/p\u003e\u003ch3\u003eDoes this module include relay outputs?\u003c\/h3\u003e\u003cp\u003eYes, the 01 suffix indicates a single relay output configuration for Alert and Danger alarm conditions.\u003c\/p\u003e\u003ch3\u003eWhat type of sensors does this module support?\u003c\/h3\u003e\u003cp\u003eIt is designed to accept inputs from proximity probes via Proximitor sensors.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":50965572485372,"sku":"3300\/46-XX-XX-01-00","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_e7dbb3b6-6e52-4489-9532-4672bac337c1.jpg?v=1786413901","url":"https:\/\/www.electronicplc.com\/products\/bently-nevada-3300-65-13-01-00-00-01-00-keyphasor-module","provider":"Electronic PLC","version":"1.0","type":"link"}
