Bently Nevada Seismoprobe Velocity Transducer Systems are engineered for precise vibration monitoring of bearing housings, machine casings, and structural components. These two-wire transducer systems measure absolute vibration (relative to free space), providing reliable diagnostics in a variety of industrial environments.

Utilizing moving-coil sensor technology, these transducers produce a voltage output directly proportional to vibration velocity. Unlike solid-state velocity sensors, which use internal integration of acceleration signals, Seismoprobe systems offer greater immunity to shock and impulsive forces, making them ideal for specialized applications and rugged environments.

Each system includes a Seismoprobe transducer, a compatible cable, and optionally a velocity-to-displacement converter, depending on application requirements. The transducers operate without external power, making them ideal for portable vibration measurement tasks and systems where simplicity and durability are key.

While Bently Nevada’s Velomitor® series may offer more robust solid-state solutions for common applications, Seismoprobe systems are preferred in installations where mechanical reliability and passive operation are essential.
