Product Introduction
The Bently Nevada 9200-01-01-01-00 Two-Wire Velocity Seismoprobe Transducer is a precision industrial automation module designed for vibration monitoring in rotating machinery. This transducer converts mechanical velocity into an electrical signal, enabling early detection of bearing wear, imbalance, and misalignment. Its robust construction and high sensitivity make it ideal for continuous operation in harsh environments.
Part of the Model 9200 series, the Bently Nevada 9200-01-01-01-00 features a two-wire configuration that simplifies wiring and reduces installation costs. With a mounting angle of 0° ±2.5° and a minimum operating frequency of 4.5 Hz (270 cpm), it provides accurate readings even at low rotational speeds.
Technical Specifications Breakdown
The Bently Nevada 9200-01-01-01-00 delivers a sensitivity of 20 mV/mm/s (500 mV/in/s) with ±5% accuracy when properly terminated and oriented at the calibration angle. This high sensitivity ensures reliable detection of subtle vibration changes. The calibration load is 10 kΩ across terminals A and B, and the sensitivity temperature coefficient is 0.2%/°C, maintaining stability across temperature variations.

-
Centrifugal Pumps and Compressors: Detect imbalance and misalignment in rotating assemblies operating at varying speeds.
-
Electric Motors and Generators: Provide continuous vibration data for condition-based monitoring programs.
By using the Bently Nevada 9200-01-01-01-00, facilities can reduce downtime and extend equipment life—a key ROI benefit for maintenance-intensive operations.
Installation & Setup Guidance
Proper mounting is critical for accurate measurements. The Bently Nevada 9200-01-01-01-00 uses a circular mounting base with a 1/4-20 UNC stud. Install the transducer at the specified orientation (0° ±2.5° angle) using a torque wrench to ensure consistent coupling. The connector option is a top-mount (no cable); connect a shielded twisted pair cable to terminals A and B, terminating with a 10 kΩ load at the monitoring instrument.
For low-frequency applications (down to 4.5 Hz), ensure the transducer is securely fastened to a flat, clean surface with minimal background vibration. Avoid mounting near sharp edges or on loose structures that can introduce noise.
Maintenance & Reliability
The Bently Nevada 9200-01-01-01-00 requires minimal maintenance due to its hermetically sealed, dust- and moisture-resistant construction. The anodized aluminum A204 case and neoprene gasket protect internal components. Periodic visual inspection for physical damage and check of cable integrity is recommended every 6 months. Operating within the -29°C to +121°C range ensures long-term stability. For high-humidity environments, use the integral cable option to maintain full moisture protection.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 9200-01-01-01-00, verify your mounting angle requirements and connector preferences. This model includes a top mount connector and circular base; alternative connector and base options are available in the 9200 series. Ensure your monitoring system accepts a two-wire velocity input with 20 mV/mm/s sensitivity.
