Product Description:

The Bently Nevada 9200-02-20-10-00 is a two-wire Seismoprobe Velocity Transducer used to measure absolute bearing housing, casing, or structural vibration. It operates using a self-generating moving-coil mechanism, making it highly robust against impact shocks. Bently Nevada Seismoprobe Velocity Transducer Systems are designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration. The two-wire systems consist of a transducer and appropriate cable. The Seismoprobe family of velocity transducers is a two-wire design that uses moving-coil technology. It provides a voltage output directly proportional to the transducer's vibration velocity.

Frequently Asked Questions (FAQ)

Q:Can this specific model be mounted horizontally?

A:No. The -02- modification explicitly dictates a vertical configuration. Mounting a 0° calibrated moving-coil transducer horizontally will lock or misalign its internal spring mass, resulting in completely inaccurate or flatlined data. If you need a horizontal setup, you must purchase the specific 90° version (such as option -03-).
Q:What is the maximum permissible cable distance?
A:You can run up to 305 meters (1,000 feet) of field wiring between this Seismoprobe sensor and your monitor (such as a Bently Nevada 3500 Monitoring System) without significant signal degradation. Consult the 9200 Transducer Datasheet for custom lengths requiring high-frequency roll-off calculations.

Q:How does moving-coil technology differ from solid-state sensors?
A:Unlike modern piezo-velocity sensors , which are accelerometers that electronically integrate the signal inside the casing, the 9200 series uses a physical moving coil. This makes the 9200 series significantly less sensitive to impact or cross-axis excitation shocks, ensuring a cleaner velocity profile on specific raw machinery components.
