Product Overview

The Bently Nevada 130732-01 is a high-performance Velomiter Terminal Card designed for the 3300 series machinery protection system. This circuit board assembly serves as the critical interface between seismic velocity transducers and the monitoring rack, facilitating dual-channel signal processing for absolute vibration measurement. By supporting multiple sensor technologies, including Velomitor® piezo-velocity sensors and Velocity Seismoprobe® transducers, the 130732-01 eliminates the requirement for external signal conditioning modules. Its primary function is to provide the 3300 system with precise, real-time casing vibration data, enabling automated machinery protection and providing essential diagnostic information for Turbine Supervisory Instrumentation (TSI) applications.
