Product Introduction
The Bently Nevada 16699-03-05-03 Velocity Seismoprobe is a high-performance seismic velocity transducer specifically designed for industrial machinery vibration monitoring. It converts mechanical vibration into a proportional electrical signal, making it a critical component in predictive maintenance and machinery protection systems.
Unlike proximity probes, which measure displacement, this seismoprobe is optimized to capture low-to-medium frequency velocity vibrations, which are particularly important in monitoring bearings, turbines, compressors, and gearboxes. With its rugged construction, the 16699-03-05-03 is engineered to withstand harsh industrial environments while maintaining high accuracy and long-term stability.
The device is frequently used with Bently Nevada 3300, 3500, and other condition monitoring systems, providing reliable input for both protection and diagnostic purposes. It is widely trusted across industries such as oil and gas, power generation, petrochemical, and heavy manufacturing.
