Product Overview

The 9200-01-05-10-00 is a two-wire, self-generating velocity sensor from Bently Nevada’s Seismoprobe family, specifically engineered to measure absolute casing vibration. Utilizing a moving-coil design, this transducer converts mechanical motion into a voltage signal directly proportional to the velocity of the vibration. Because it requires no external excitation or power supply, the 9200-01-05-10-00 is an exceptionally reliable solution for both permanent monitoring and temporary diagnostic surveys. It is particularly valued in industrial settings for its ability to ignore high-frequency "noise" or mechanical shocks that often trigger false alarms in accelerometer-based systems, providing a cleaner signal for low-to-mid-range frequency analysis.

Machinery Integration and Deployment Context

The 9200-01-05-10-00 Seismoprobe is primarily deployed on large-scale rotating machinery equipped with rolling-element bearings where casing vibration is a reliable indicator of asset health. It is a standard choice for monitoring industrial fans, centrifugal pumps, blowers, and medium-to-large electric motors. In the power generation and oil and gas sectors, it is frequently utilized to detect common mechanical faults such as rotor unbalance, structural looseness, and misalignment. Because the velocity signal provided by the 9200 series is less susceptible to high-frequency impact excitation than acceleration signals, it is ideal for machines with significant background noise. When connected to a Bently Nevada 3500 series monitor or a portable data collector, this transducer provides the deterministic data required for proactive maintenance and machinery protection.
