Description
Bently Nevada 74712-03-10-02-00 Seismoprobe Velocity Transducer Technical Specification
Brand: Bently Nevada (Baker Hughes)
Model: 74712-03-10-02-00
Product Name: High-Temperature Seismoprobe Two-Wire Velocity Transducer
Country of Origin: United States
HS Code: 85437099
-
74712-03-10-02-00
Dimensions: 102 mm overall length × 41 mm outer diameter
Weight: 0.48 kg, excluding connecting cable and mounting accessories
Input:
No external power supply input required; it is a self-powered passive transducer. Physical vibration movement of machinery casing or bearing housing serves as measured mechanical input. Internal coil DC resistance is 1250 Ω ±5 %, typical locked-coil inductance 125 mH. Maximum allowable total field cable length reaches 305 meters when matched with compatible monitoring modules.
Output Interfaces:
Two-wire analog voltage output directly proportional to vibration velocity, nominal sensitivity 20 mV/mm/s (500 mV/in/s), tolerance ±5 % under calibrated installation orientation. Signal is transmitted through side-mounted two-pin electrical connector to external monitoring equipment. No built-in digital communication interface; analog vibration voltage shall be conditioned and processed by matched Bently Nevada monitoring hardware.
Key Technical Characteristics:
Continuous operating temperature ranges from -29 °C to +204 °C for high-temperature working conditions; storage temperature covers wider temperature range. Frequency response 4.5 Hz-1000 Hz defined by model option-03. Maximum transverse sensitivity ≤10 % of axial rated sensitivity at 100 Hz. Withstands peak mechanical shock up to 50 g on non-sensitive transverse axis. Relative humidity tolerance 5 %-95 % non-condensing, resistant to oil mist, dust and moist atmosphere in turbine compartments. M10×1 threaded-stud mechanical mounting design for direct bolt-on installation on equipment housing. No on-board LED indicators; all vibration data and fault diagnostics are completed in upper-level monitoring system. Passive sensor design simplifies field wiring and reduces auxiliary power-supply risks. Factory pre-calibrated before delivery, suitable for permanent online monitoring as well as temporary portable vibration measurement. Complies with industrial EMC requirements for heavy-industry rotating-equipment protection applications.
