Description
The Bently Nevada 9200-06-02-10-00 is a high-performance seismic velocity transducer designed to measure absolute vibration of bearing housings, casings, or structural supports. It is a “Two-Wire” system that outputs a voltage proportional to the vibration velocity of the machine.

Country of Origin
This instrumentation sensor is manufactured by Bently Nevada (a Baker Hughes business) in the United States, adhering to rigorous mechanical and electrical standards for industrial machinery protection.
Application Fields
The 9200 series is specifically used for machines with high casing-to-rotor mass ratios:
- Hydroelectric Turbines: Monitoring low-frequency vibrations on bearing pedestals.
- Large Fans and Blowers: Detecting structural resonance or unbalance.
- Reciprocating Compressors: Monitoring frame vibration and cylinder motion.
- Industrial Pumps: Assessing the mechanical health of pump casings in harsh environments.
Product Usage Instructions
- Mounting: Prepare a flat, smooth surface on the machine casing. Install the 1/4-28 mounting stud and torque the transducer to the specified value (typically 4.5 Nm).
- Orientation: Ensure the transducer is mounted within its specified orientation range (-06). Mounting a vertical sensor horizontally will result in significant measurement errors.
- Wiring: Connect the two-wire cable to the terminal block. Because this is a self-generating transducer, it does not require external power to produce a signal, but it must be connected to a high-impedance monitor input.
- Cabling: Use shielded twisted-pair cabling to prevent noise pickup. Route the cable through a conduit or secure it with clips to avoid fatigue from machine vibration.
- Calibration: Verify the sensor’s sensitivity using a handheld shaker table at a reference frequency (e.g., 80 Hz or 100 Hz) before finalizing the installation.
Product Technical Description
The 9200-06-02-10-00 operates on the moving-coil principle. Technically, it consists of a permanent magnet suspended on springs inside a wire coil. As the machine vibrates, the coil moves through the magnetic field, inducing a voltage proportional to the velocity of the motion. Unlike proximity probes which measure relative displacement, the Seismoprobe measures “absolute” vibration relative to free space. Its rugged, hermetically sealed stainless steel housing makes it ideal for permanent installation in wet or corrosive industrial environments.
Q&A (Common Questions)
Q: Does this transducer require a Proximitor? A: No. Unlike Bently Nevada proximity probes, the 9200 series Seismoprobes are self-generating and connect directly to a monitor or data collector input.
Q: Can I mount this sensor at any angle? A: No. The -06 option is designed for specific vertical/upright angles. For horizontal mounting, you would typically need the -01 or -03 orientation options.
Q: What is the difference between the 9200 and the 47220 transducers? A: The 9200 is a standard-temperature transducer, whereas the 47220 is a high-temperature version designed for environments exceeding 121°C.
Q: How do I troubleshoot a low signal? A: Check for loose mounting or improper orientation first. Then, measure the coil resistance with an ohmmeter; an open circuit or very high resistance usually indicates internal damage.
