This module is designed to provide continuous, high-integrity surveillance of radial vibration in rotating machinery. By processing input from Proximitor sensors or seismic transducers, the unit translates raw electrical signals into actionable mechanical data. It features an integrated dual-channel display that allows operators to monitor peak-to-peak vibration levels in real-time. With its dedicated alarm circuitry and localized signal conditioning, this monitor acts as a primary defense against mechanical failure, providing the necessary trip logic to protect high-value industrial assets from excessive oscillatory stress.\u003c\/p\u003e\n\u003ch3\u003eCritical Electromechanical Specifications\u003c\/h3\u003e\n\u003cp\u003eThe 3300\/15 is built to satisfy stringent API 670 requirements, ensuring precision signal processing and robust environmental resistance.\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Identifier:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3300\/15-03-01-01-00-00-00\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAssembly Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e78392-01\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMeasurement Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0 to 10 mils peak-to-peak (PP) full scale\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRecorder Output:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIsolated +4 to +20 mA DC analog signals\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eTransducer Sensitivity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCalibrated for 7200 mV\/mm (approx. 200 mV\/mil) scale factors\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eChannel Count:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDual independent monitoring paths\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVisual Interface:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFront-mounted digital LCD for direct vibration readout\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSignal Integrity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated OK\/Not OK self-diagnostic circuitry\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNet Weight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1.15 kg\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eExternal Dimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2.5 cm x 24.5 cm x 24.2 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAlarm Architecture:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eConfigurable Alert and Danger setpoints with relay outputs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUSA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Deployment Scenarios\u003c\/h3\u003e\n\u003ch3\u003eSteam and Gas Turbine Protection\u003c\/h3\u003e\n\u003cp\u003eIn power generation, the 3300\/15 is utilized to track the radial shaft vibration of turbines.
