The 9200-09-01-06 is a variant of the 9200 Seismoprobe Velocity Transducer, a two-wire moving-coil sensor. It is used to measure absolute bearing housing, casing, or structural vibration on industrial machinery.
Using dynamic coil technology
With an impact resistance of up to 50 g
The analog voltage signal is directly proportional to the vibration velocity
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.

Thermal Power
Used for monitoring the casing vibration of large boiler feedwater pumps, forced draft (FD) fans, induced draft (ID) fans, and coal pulverizers.
Hydroelectric Power
Applied in measuring the absolute vibration of bearings in hydro-generator sets, especially for units operating at low speeds.
Oil & Gas
Monitors structural vibrations of long-distance pipeline oil transfer pumps and water injection pumps on offshore rigs or onshore oilfields.
Petrochemical & Refining
Monitors the mechanical vibration of reciprocating compressor frames, large centrifugal pumps, and cooling tower fans to prevent unscheduled downtime.
Pulp & Paper Industry
Monitors the vibrations of paper machine dryer bearings, vacuum pumps, and large refiners in pulp processing.
Air Separation
Monitors bearing casing vibrations of critical large centrifugal air compressors, oxygen compressors, and nitrogen compressors in air separation units.
When using the 9200-09-01-06, it is essential to strictly adhere to the officially specified mounting torque to prevent overtightening damage, ensure proper grounding of the shielded two-wire cable in high electromagnetic interference environments, strictly avoid drops or severe impacts due to its internal permanent magnet and moving-coil structure, and periodically measure the pin-to-pin DC resistance to monitor the internal coil condition.
9200-09-01-06 is a self-generating, two-wire Seismoprobe velocity transducer manufactured by Bently Nevada that is specifically used to measure the absolute vibration of casings or bearing housings. This specific model features an omnidirectional mounting capability of 0±180° with an operating frequency range from 15 to 1000 Hz, and it utilizes a top-mounted two-pin connector along with a circular mounting base with a 1/4-20 UNC stud. It can directly output an AC voltage signal with a sensitivity of 20 mV/mm/s and is rigidly fixed to the measured surface, typically connecting with monitoring modules such as the 3500 system.
9200-09-01-06 is an industrial-grade two-wire Seismoprobe velocity transducer manufactured by Bently Nevada, designed to measure absolute bearing housing, casing, or structural vibration.
What is the core working principle of 9200-09-01-06?
It utilizes moving-coil technology, where the relative movement of an internal coil within a magnetic field directly generates a voltage output proportional to the vibration velocity, requiring no external power.
How to correctly install the 9200-09-01-06 transducer?
Drill and tap a hole on a flat casing surface, rigidly fix the transducer to the measurement point vertically or at the designed angle using its 1/4-20 UNC stud, and apply the specified torque.
How to make electrical connections and wiring for 9200-09-01-06?
It is a two-wire system. Via its top connector, it connects to an original matching shielded two-wire cable, and the positive/negative signal wires are directly routed to the backend monitoring monitor or acquisition module.
What are the advantages of this moving-coil transducer compared to solid-state velocity transducers?
The moving-coil design is less sensitive to external impacts or impulsive excitation, providing more stable fundamental frequency velocity measurements in harsh industrial environments with high-frequency noise.
