Products Description
The Bently Nevada 9200-03-05-10-00 Seismoprobe Velocity Transducer system is engineered to provide precise measurement of absolute vibration of bearing housings, machine casings, or supporting structures. This two-wire system includes the Seismoprobe transducer and the appropriate cable, offering a compact and reliable solution for industrial vibration monitoring.
Using moving-coil technology, the Seismoprobe transducer produces a voltage output directly proportional to vibration velocity, providing straightforward, high-fidelity measurement without the need for additional signal processing. Unlike solid-state velocity transducers, which are essentially accelerometers with integrated electronics, moving-coil transducers are less sensitive to impact or impulsive excitation, making them particularly suitable for applications where sudden mechanical shocks occur.
Because the 9200-03-05-10-00 Seismoprobe does not require external power, it is ideal for both fixed industrial installations and portable measurement applications. Its robust design and simplicity ensure reliable vibration monitoring in demanding industrial environments while minimizing setup complexity.

Advantages
The Bently Nevada 9200-03-05-10-00 Seismoprobe provides highly accurate absolute vibration velocity measurement for bearing housings, machine casings, and structural components. Using moving-coil technology, it delivers a voltage output proportional to vibration velocity, ensuring reliable monitoring across a wide range of amplitudes and frequencies. With excellent amplitude linearity and a low temperature sensitivity coefficient, the transducer maintains precise readings even in environments with temperature fluctuations. Its high shock resistance and low transverse sensitivity make it durable in harsh industrial conditions, providing operators with confidence in early fault detection and effective machinery protection.
Industrial Applications
The 9200 Seismoprobe is widely used to monitor rotating machinery such as turbines, compressors, and pumps. By measuring absolute vibration velocity directly at the bearing or casing, it allows predictive maintenance teams to detect imbalance, misalignment, or bearing wear before failures occur. Its robust construction, high shock tolerance, and low sensitivity to impulsive events ensure accurate readings even in mechanically noisy environments. This enables plant operators to maintain continuous operation while minimizing unplanned downtime, enhancing both safety and equipment longevity.
