Bently Nevada 9200-06-05-10-00 Seismoprobe Velocity Transducer

Description

The Bently Nevada 9200-06-05-10-00 is a two-wire velocity transducer engineered for continuous monitoring or periodic measurements of absolute structural, casing, or bearing housing vibration. Operating via moving-coil technology, this system delivers a voltage output directly proportional to the mechanical vibration velocity without requiring an external power source. The 9200-06-05-10-00 configuration is specifically less sensitive to impact or impulsive excitation compared to solid-state sensors, making it ideal for standard casing velocity applications across critical machinery like turbines, fans, and pumps.

Features

• Two-wire moving-coil technology design providing an direct voltage output without external power
• Reduced sensitivity to impact or impulsive excitation compared to solid-state alternatives
• Suitable for both continuous machinery protection and periodic portable diagnostics
• High-grade anodized aluminum casing providing robust resistance to industrial environmental factors

Applications

• Absolute bearing housing and casing vibration measurement on rotating machinery
• Steam and gas turbine structural vibration monitoring
• Portable test instrument data collection and diagnostics
• Balance and misalignment tracking on heavy industrial fans and pumps

Installation Guidelines

• Orientation Alignments: Ensure the transducer is installed strictly within its specified 0 ±100 vertical boundaries relative to the machine axis.
• Torque Application: Tighten the M10X1 mounting base option to exactly 5.6 Nm (50 in-lb) during seating to preserve optimal amplitude and frequency response.
• Signal Fidelity: Verify that structural or rotor vibration paths are faithfully transmitted to the bearing housing or casing location chosen for the transducer installation.
• Moisture Countermeasures: Ensure the top-mounted terminal block enclosure is sufficiently protected against dust and moisture ingestion to fit local environmental ratings.

FAQ

Does the 9200-06-05-10-00 require an external power supply to operate?

No, this transducer leverages a moving-coil architecture which inherently creates its own voltage signal output proportional to the vibration velocity without external power.

What is the minimum operating frequency threshold for this precise configuration?

This specific unit uses the -06 option, which defines a minimum operating frequency threshold of 10 Hz (600 cpm).

How should the sensor signal cable be handled over long distances?

The system supports up to 305 meters of leadwire between the velocity sensor and a 3300 or 3500 series monitor, though you should consult the manual for high-frequency roll-off parameters when using extended lengths.

What are the primary differences between this moving-coil sensor and solid-state alternatives?

Moving-coil sensors display much lower sensitivity to impact or impulsive excitations compared to embedded integration solid-state alternatives, providing specific advantages on designated casing installations.
