Bently Nevada 16699-10-02-02 Velocity Seismoprobe

Product Description

The Bently Nevada 16699-10-02-02 Velocity Seismoprobe is an industrial vibration sensor engineered for direct measurement of absolute casing vibration on rotating equipment. Unlike displacement probes that monitor shaft motion, this seismoprobe focuses on machine housing behavior, providing critical insight into overall mechanical condition.

Designed for long-term operation in harsh industrial environments, the sensor converts vibration velocity into a stable electrical output suitable for continuous monitoring and machinery protection systems. It is commonly deployed on turbines, compressors, pumps, motors, and generators where casing vibration trends are required for early fault detection.

This model features an integrated long-length cable, rugged construction, and standardized sensitivity, allowing straightforward integration with Bently Nevada monitoring platforms and third-party vibration systems.

Key Technical Characteristics

The 16699-10-02-02 is based on a velocity-sensing principle optimized for low- to mid-frequency machinery vibration, making it well suited for detecting common mechanical faults such as imbalance, misalignment, structural looseness, and resonance.

Its output is proportional to vibration velocity, simplifying signal interpretation and trending in condition monitoring software.

FAQ

What type of vibration does this sensor measure?
The 16699-10-02-02 measures absolute vibration velocity of the machine casing, not shaft displacement.

Is this probe suitable for high-temperature environments?
It is rated for continuous operation up to +120 °C, which covers most industrial machinery applications.

Can it be used with non-Bently Nevada systems?
Yes, as long as the monitoring system accepts standard velocity transducer voltage signals and matching sensitivity.
