Transducteur de vitesse Seismoprobe Bently Nevada 9200-06-05-05-00

Description

The Bently Nevada 9200-06-05-05-00 is a two-wire velocity transducer designed for continuous monitoring or periodic diagnostics of absolute casing, bearing housing, or structural vibration. Utilizing moving-coil technology, this instrument generates a voltage output directly proportional to the transducer's vibration velocity without requiring external operating power. The unique mechanical architecture of the 9200-06-05-05-00 ensures low sensitivity to impact or impulsive excitation, delivering highly reliable and repeatable dynamic data on critical machinery such as turbines, pumps, and industrial fans.

Features

• Moving-coil technology provides a direct voltage output without the need for external power.
• Low sensitivity to impact or impulsive excitation compared to solid-state alternatives.
• Two-wire engineering supports both permanent machinery protection and portable field measurements.
• Durable anodized aluminum case construction for survival in aggressive industrial environments.

Applications

• Absolute bearing housing and machinery casing vibration measurements.
• Steam and gas turbine casing monitoring protocols.
• Periodic data collection using portable test and diagnostic equipment.
• Structural vibration analysis on large-scale balance-of-plant equipment.

Installation Guidelines

• Orientation Alignment: The transducer must be physically mounted within its designated 0 ±100 vertical limits relative to the calibration angle.
• Torque Rating: Tighten the integrated 1/2-in 20 UNF-3A mounting thread to exactly 5.6 Nm (50 in-lb) to guarantee optimal frequency transmission.
• Vibration Path: Ensure the chosen structural interface point faithfully transmits internal rotor malfunctions to the external casing where the transducer sits.
• Environmental Sealing: Verify that the top terminal block connector is fully buttoned up and sealed against regional dust and moisture entry.

FAQ

What does the 05 mounting base configuration indicate?

The -05 code indicates that the transducer is supplied with no separate circular or rectangular flange base; instead, it features an integrated 1/2-in 20 UNF-3A threaded stud directly on the bottom for mounting.

What is the minimum operating frequency limits of this velocity sensor?

This model incorporates the -06 frequency option, establishing a low-end frequency limit of 10 Hz (600 cpm) before signal attenuation starts.

How does the moving-coil principle benefit this transducer over standard accelerometers?

Because it utilizes moving-coil technology rather than solid-state integration crystals, it is substantially more resilient and less sensitive to mechanical impacts or abrupt impulsive shocks.

Is an external power supply or charge amplifier required for wiring?

No, this two-wire velocity system is entirely self-generating and creates a direct voltage output signal from the internal coil movement, making it highly versatile for portable and diagnostic tasks.
