Product Details: Bently Nevada 9200-09-01-02-01 is a Seismoprobe two-wire Velocity Transducer, adopting moving-coil self-generating technology without external power supply, used to measure absolute casing vibration of rotating machinery. This Seismoprobe Vibration Sensor outputs voltage signal directly proportional to vibration velocity, which can be connected to rack monitoring modules or portable vibration analyzers to continuously collect bearing housing vibration data. The sensitivity is 20 mV/mm/s (500 mV/in/s), with tolerance within ±5%. According to ordering specification 9200-09-01-02-01, this transducer supports 0~180° full rotation mounting angle, carries CSA Class I Division 2 hazardous area certification, and uses 1/4-28 UNF stud mounting base. The operating temperature range is -29℃ ~ +121℃, suitable for high temperature casing environments. The frequency response starts at 15Hz up to 1kHz, transverse sensitivity ≤10%, and can withstand 50g mechanical impact on transverse direction. During installation, the sensor must be tightly fixed on machine casing surface, keep the sensitive axis perpendicular to vibration direction, avoid loose mounting which will cause signal distortion. Match with 9571 series shielded interconnect cable for signal transmission, separate signal cable from high voltage power cables to reduce electromagnetic interference. Regular maintenance needs visual inspection of housing corrosion and thread damage, check connector and cable sheath for aging. It can be calibrated periodically by vibration shaker. Widely used in power generation, petrochemical and heavy industrial fields, this Absolute Vibration Transducer monitors turbines, centrifugal compressors, generators, fans and pumps, tracks casing vibration trend, realizes early bearing fault warning and prevents unplanned equipment shutdown.
