Brand New Bently Nevada 9200-01-02-02-00 Seismoprobe

Product Overview

The Bently Nevada 9200-01-02-02-00 is a professional-grade, two-wire Seismoprobe velocity transducer specifically designed to measure absolute casing vibration on rotating machinery. This seismic sensor utilizes moving-coil technology to provide a self-generated voltage output proportional to vibration velocity, eliminating the need for external power in many applications. It serves as a primary diagnostic tool for monitoring bearing housings, gearboxes, and small pumps where shaft-relative measurement is not feasible. We supply this unit as 100% Brand New and Original in factory packaging, fully compatible with Bently Nevada 3300 and 3500 series monitoring racks.

Part Number Breakdown: 9200-01-02-02-00

The 9200 series utilizes a specific coding structure to define mounting, connector, and agency approval options.

Technical Specifications

Engineering Advantages

• Self-Generated Power: The 9200 series utilizes a moving-coil design that generates its own electrical signal from mechanical motion. This eliminates the requirement for external excitation power, simplifying field wiring and reducing potential failure points in the signal loop.

• Low-Frequency Performance: With a natural frequency of 10 Hz, this seismoprobe captures low-speed vibration data critical for detecting imbalance and misalignment in large-frame motors and cooling tower fans.

• Ruggedized Signal Integrity: The stainless steel housing protects internal components from corrosive environments. The two-wire balanced output configuration provides excellent rejection of common-mode noise, ensuring clean data transmission even over long cable runs in high-EMI plant areas.

• Ease of Installation: The 3/8-24 UNF stud mount facilitates rapid attachment to bearing housings. This mounting method ensures a rigid mechanical bond, which is essential for accurate high-frequency response and repeatable diagnostic data.

FAQs

Q: Can the 9200-01-02-02-00 replace a standard accelerometer?

A: While both measure casing vibration, the 9200 series outputs velocity, whereas an accelerometer outputs acceleration. Most Bently Nevada 3500/42M monitors can accept either, but you must verify the monitor configuration to ensure the correct units are displayed.

Q: Does this sensor require an external Proximitor?

A: No. Unlike proximity probes, this seismic transducer is a self-contained unit. It does not require a Proximitor or external driver; it connects directly to the monitor or a junction box via a standard 2-conductor shielded cable.

Q: What is the benefit of a "Two-Wire" system for this model?

A: The two-wire design simplifies the wiring architecture. It reduces cable costs and makes the 9200-01-02-02-00 an ideal candidate for retrofitting older machinery that uses legacy seismic sensors.

Q: How does this model handle high-vibration environments?

A: The moving-coil architecture is exceptionally durable. It resists mechanical shock better than many piezoelectric designs, making it suitable for high-impact industrial applications such as reciprocating compressors and rock crushers.
