Bently Nevada 16699-03 Velocity Seismoprobe

Seismic Velocity Measurement with the 16699-03

The 16699-03 measures casing vibration velocity on rotating machinery in power and process plants. This seismoprobe converts structural movement into an electrical signal for monitoring systems. Reliability engineers therefore mount it on bearing housings and gearbox casings. Its threaded stud installs directly onto machined surfaces without adapters.

Detailed Technical Parameters

Frequency response defines the 16699-03, because the internal moving coil generates voltage proportional to velocity. The sealed housing shields the sensing element from oil mist and dust. Meanwhile, the integral cable carries the signal to the monitor rack. Review the essential specifications in the table below.

Integration into Monitoring Systems

The 16699-03 threads onto the machine casing and routes its cable to the monitor rack. Technicians therefore complete installation without separate drivers or junction boxes. Consequently, vibration channels start collecting data within minutes. The probe requires no external power and generates its own signal. Furthermore, the sturdy housing withstands vibration, heat, and oil exposure on turbine decks.

Why Plants Choose This Probe

Many power stations still rely on seismic probes for proven machinery protection. Hence, the 16699-03 serves as a dependable spare for keeping velocity channels online. Its standardized thread format simplifies stock management across multiple sites. In addition, the passive design eliminates calibration drift and power supply faults. This probe keeps casing vibration data accurate and maintenance schedules on track.
