Bently Nevada 9200-06-02-01-00 Velocity Seismoprobe

Overview

The 9200-06-02-01-00 Velocity Seismoprobe from Bently Nevada is an industrial vibration sensor developed for direct measurement of absolute casing vibration on rotating machinery. Unlike displacement-based probes, this velocity transducer delivers a signal proportional to vibration speed, making it well suited for assessing overall mechanical condition and structural response.

Designed for continuous operation in demanding environments, the 9200-06-02-01-00 provides stable, low-noise output and long-term measurement reliability for critical assets such as turbines, compressors, pumps, and large motors.

Operating Principle

This sensor uses an internal piezoelectric velocity sensing element that converts mechanical motion of the machine casing into an analog voltage signal. The output directly represents vibration velocity, simplifying integration with machinery protection and condition monitoring systems.

Velocity measurement is particularly effective for identifying imbalance, misalignment, looseness, and resonance across a broad operating speed range.
