9200 and 74712 Seismoprobe Velocity Transducers

Description

Bently Nevada Seismoprobe Velocity Transducer Systems are designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration. The two-wire systems consist of a transducer and appropriate cable.

The Seismoprobe family of velocity transducers is a two-wire design that uses moving-coil technology. It provides a voltage output directly proportional to the transducer's vibration velocity.

Moving-coil transducers are less sensitive to impact or impulsive excitation than solid-state velocity transducers, which are inherently accelerometers with embedded integration electronics.

Moving-coil transducers are less sensitive to impact or impulsive excitation and can represent a good choice for certain applications. Because they don’t require external power, they are convenient for portable measurement applications.

For most installations, Bently Nevada's Velomitor family of velocity transducers, which incorporate solid-state technology, provide improved performance and ruggedness for casing velocity measurement applications.

Available Types

Two types of Seismoprobe Velocity Transducer are available: l 9200: The 9200 is a two-wire transducer suitable for continuous monitoring or for periodic measurements in conjunction with test or diagnostic instruments. When ordered with the integral cable option, the 9200 has excellent resistance to corrosive environments without need of additional protection. l 74712: The 74712 is a high temperature version of the 9200. Interconnect cables are available for connecting the 9200 and 74712 transducers to other instruments. These cables are available in various lengths with or without stainless steel armor. When ordering the 9200 and 74712 Seismoprobe Velocity Transducers, expect approximately a six week lead time. That lead time can vary based on component availability and configuration. For projected lead times for your specific order, contact your local Bently Nevada representative.

Specifications   

Specifications are at approximately +22°C (+72°F) with 25 mm/s (1 in/s) of machine casing vibration at 100 Hz (6000 cpm) with a 10 kΩ load unless otherwise specified.
