This measurement is critical for steam turbines and other large rotating machinery where casing growth can lead to mechanical interference. The monitor continuously compares expansion values against configured alarm setpoints, providing early warning of abnormal conditions to facilitate predictive maintenance.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMeasures casing expansion relative to the foundation.\u003c\/li\u003e\n\u003cli\u003eContinuous parameter comparison against Alert and Danger alarm setpoints.\u003c\/li\u003e\n\u003cli\u003eRelay actuation for alarm conditions.\u003c\/li\u003e\n\u003cli\u003eLED indicators for OK, Bypass, Alert, and Danger status.\u003c\/li\u003e\n\u003cli\u003eCompatible with proximity probes or LVDT signals.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is primarily utilized in power generation and industrial facilities for monitoring steam turbine thermal growth, ensuring mechanical alignment and preventing casing damage during thermal cycling.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e3300\/48-03-02-02-00\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\u003e~1.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003e200 mV\/mil or 100 mV\/mil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/- 0.33% typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003e4-20 mA, 1-5 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 powered down before inserting or removing the module.\u003c\/li\u003e\n\u003cli\u003eHandle the module using standard ESD precautions to prevent damage to internal circuitry.\u003c\/li\u003e\n\u003cli\u003eEnsure the module is fully seated in the rack slot to maintain proper backplane connection.\u003c\/li\u003e\n\u003cli\u003eUse shielded cabling for transducer inputs to minimize EMI interference.\u003c\/li\u003e\n\u003cli\u003eVerify that the transducer signal type matches the module configuration settings.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the 3300\/48 monitor?\u003c\/h3\u003e\u003cp\u003eThe module monitors the thermal expansion of turbine casings relative to the foundation, which is essential for preventing mechanical interference in large rotating machinery.\u003c\/p\u003e\u003ch3\u003eCan this module be used with different types of sensors?\u003c\/h3\u003e\u003cp\u003eYes, the 3300\/48-03-02-02-00 is configured to accept inputs from proximity probes or LVDTs, depending on the specific application requirements.\u003c\/p\u003e\u003ch3\u003eWhat do the alarm setpoints control?\u003c\/h3\u003e\u003cp\u003eThe module provides relay outputs for Alert and Danger conditions, which can be integrated into the plant's safety or control systems to trigger alarms or automated shutdowns.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":50986350772476,"sku":"3300\/48-03-02-02-00","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_2ad0b867-750a-45ff-9bc0-0007df83e0c0.jpg?v=1786819792","url":"https:\/\/www.electronicplc.com\/products\/bently-nevada-3300-14-01-22-00-relay-module","provider":"Electronic PLC","version":"1.0","type":"link"}
