By monitoring these expansion characteristics, the module helps prevent mechanical interference, which is vital for the integrity of steam turbines and large rotating machinery. The system provides real-time monitoring, comparing measured expansion against predefined alarm setpoints to trigger early warnings and facilitate proactive maintenance strategies.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eProvides accurate measurement of casing expansion using proximity probes or LVDT inputs.\u003c\/li\u003e\n\u003cli\u003eEquipped with onboard LED status indicators for OK, Bypass, Alert, and Danger conditions.\u003c\/li\u003e\n\u003cli\u003eIncludes configurable relay outputs for critical alarm signaling.\u003c\/li\u003e\n\u003cli\u003eSupports integration into the 3300 series rack environment for seamless data acquisition.\u003c\/li\u003e\n\u003cli\u003eDesigned for high-reliability monitoring in industrial power generation and mechanical drive applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e3300\/48-01-01-00-00\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\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eApprox. 1.5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.33% typical, ±1% maximum at 25 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Outputs\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 series rack is properly grounded before installing or removing modules to prevent electrostatic discharge (ESD) damage.\u003c\/li\u003e\n\u003cli\u003eVerify that the module is fully seated in the rack slot to ensure reliable backplane connection.\u003c\/li\u003e\n\u003cli\u003eUse shielded cabling for transducer inputs to minimize electromagnetic interference (EMI) in high-noise environments.\u003c\/li\u003e\n\u003cli\u003eAlways power down the rack system before performing maintenance or module replacement.\u003c\/li\u003e\n\u003cli\u003eEnsure adequate airflow within the cabinet to maintain the operating temperature between 0 and 60 deg C.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat type of sensors does the 3300\/48-01-01-00-00 support?\u003c\/h3\u003e\u003cp\u003eThis module is configured to accept inputs from proximity probes or linear variable differential transformers (LVDTs) via compatible Proximitor sensors.\u003c\/p\u003e\u003ch3\u003eWhat is the primary function of this module?\u003c\/h3\u003e\u003cp\u003eIt is designed to measure the thermal expansion of turbine casings relative to their foundation, providing Alert and Danger relay outputs when parameters exceed configured setpoints.\u003c\/p\u003e\u003ch3\u003eDoes this module require special certifications?\u003c\/h3\u003e\u003cp\u003eThe -01-01-00-00 configuration represents the standard version without additional specialized agency approvals.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44009511977050,"sku":"3300\/48-01-01-00-00","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/wm_1_444e6399-2cf1-4af2-9dbe-2be0643545f8.jpg?v=1788489960","url":"https:\/\/www.spareoil.com\/es\/products\/3300-16-11-01-01-00-00-00-bently-nevada-dual-vibration-monitor","provider":"SpareOil Automation","version":"1.0","type":"link"}
