The internal accelerometer assembly combines with an internal integrator circuit to output a velocity signal while maintaining precise rotor dynamics tracking. Signal transmission suppresses cross-talk interference and preserves signal integrity across long cable runs. Output validation against standard gap voltage targets and eddy-current probe scaling baselines ensures reliable diagnostic feedback for machinery health monitoring platforms.\u003c\/p\u003e\n\u003ch3\u003eOrder Delivery Package\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 330500-03-01 Velomitor Piezo-velocity Sensor\u003c\/li\u003e\n\u003cli\u003e1 1\/4 - 28 UNF Mounting Stud\u003c\/li\u003e\n\u003cli\u003e1 Product Compliance and Documentation Sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Mounting Procedures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThread Preparation: Clean the mounting surface thoroughly and apply a thin film of silicone grease or machine oil to optimize high-frequency seismic transmission across the interface.\u003c\/li\u003e\n\u003cli\u003eTorque Application: Thread the sensor firmly onto the 1\/4 - 28 UNF mounting stud, applying the recommended torque to prevent mechanical loosening under heavy casing vibrations.\u003c\/li\u003e\n\u003cli\u003eShielded Cabling: Route signal cables through dedicated metallic conduits, ensuring shield drain wires are grounded at the monitor end only to eliminate ground loops.\u003c\/li\u003e\n\u003cli\u003eEnvironmental Clearance: Verify that the local operating envelope remains within thermal limits to protect internal piezoelectric elements from thermal shock or degradation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What is the nominal voltage output sensitivity of this sensor?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: The sensitivity is specified at 3.94 mV\/mm\/s, which corresponds to 100 mV\/in\/s with a tolerance of plus-minus 5 percent.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What mounting thread configuration does the -03 option provide?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: The -03 suffix designates a 1\/4 - 28 UNF threaded stud interface for direct mechanical mounting onto machine casings.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What is the maximum peak velocity measurement range?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: The sensor can reliably measure vibration velocities up to 1270 mm\/s or 50 in\/s peak.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What power supply parameters are required to drive the unit?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: It requires a constant current DC source typically between 2 mA and 20 mA to power the internal integrated electronics.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What is the nominal output bias voltage of the sensor?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: The output bias voltage is -12 plus-minus 3.0 VDC referenced to Pin A over the specified temperature range.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQ: Does the -01 suffix indicate any specific safety certification?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: Yes, the -01 option indicates CSA, US, and Canadian hazardous area safety approvals for explosive environments.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What are the physical dimensions and weight profile for panel layout?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: The sensor weighs 0.16 kg with shipping dimensions measuring 2.5 x 2.5 x 7.2 cm.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQ: What is the amplitude linearity limit of the unit?\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA: Amplitude linearity is maintained within plus-minus 2 percent up to 152 mm\/s or 6 in\/s peak vibration levels.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":46026675257517,"sku":"330500-03-01","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/330500-03-01_2_-1.jpg?v=1785987704","url":"https:\/\/www.maxwellplc.com\/ga\/products\/330500-03-01-bently-nevada-3300-series-velomitor-piezo-velocity-sensors-piezo-velocity-sensor","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
