Bently Nevada 9200-03-05-01-00 9200 Two-wire Velocity Seismoprobe Transducer

Description

Monitoring absolute casing vibration is critical for detecting mechanical faults in large rotating machinery, and the Bently Nevada 9200-03-05-01-00 provides the precise measurement required for these industrial environments. This self-generating, moving-coil two-wire velocity seismoprobe transducer converts mechanical vibration into a proportional voltage output without requiring any external excitation power. This specific configuration operates on a vertical axis, making it highly effective for continuous diagnostics on critical plant assets.

The 9200-03-05-01-00 is built with an integrated circular base featuring a 1/4-in 20 UNC stud for robust physical coupling to machine casings. The top-mounted terminal block connector allows for secure wiring directly within local terminal boxes. Because it operates down to a low minimum frequency of 4.5 Hz, it is capable of tracking slow-speed structural vibrations and unbalance conditions across various turbine and pump applications.

Features

• Self-generating velocity sensor design operates without an external power source.
• Designed for vertical mounting orientations (90 degrees +/-2.5 degrees tolerance).
• Low-frequency response threshold starting at 4.5 Hz (270 cpm).
• Convenient top-mounted terminal block for simplified and secure wiring.
• Rugged circular mounting base with a integrated 1/4-in 20 UNC stud.
• Sealed, durable mechanical construction ideal for demanding industrial areas.

Applications

• Steam turbine and gas turbine casing vibration monitoring
• Industrial pump and compressor casing diagnostic systems
• Heavy-duty electric motors and generators
• Draft fans, cooling tower fans, and blowers
• General machinery protection systems in power generation and chemical plants

Installation Guidelines

Proper installation is vital for ensuring accurate vibration signal transmission. The mounting surface on the machine casing must be clean, flat, and perpendicular to the axis of measurement. Thread the 1/4-in 20 UNC mounting stud directly into the tapped hole and torque to standard engineering limits to prevent signal attenuation or sensor detachment. Align the sensor within the vertical mounting tolerance (90 degrees +/-2.5 degrees). Use shielded, twisted-pair cabling to connect the terminal block to the monitoring system, ensuring the shield is grounded at the instrument end only to prevent ground loops.
