Introduction to the 9200-09-01-01-00
When machinery vibration threatens uptime, the 9200-09-01-01-00 from Bently Nevada provides precise, dependable measurement. This two-wire velocity seismoprobe transducer is engineered for continuous monitoring in demanding industrial environments. Its robust design and clear specifications make it a trusted choice for maintenance teams seeking early fault detection.
Key Features and Technical Specifications
The 9200-09-01-01-00 offers a focused set of parameters that ensure accurate vibration data. Each specification below is directly from the manufacturer's data.
- Sensitivity: 20 mV/mm/s (500 mV/in/s), ±5% when properly terminated and oriented at the calibration angle.
- Dynamic Operating Range: 2.54 mm (0.100 in) peak-to-peak maximum displacement.
- Velocity Range: 25 mm/s (1 in/s) at +22 °C casing vibration at 100 Hz with a 10 kΩ load.
- Coil Resistance: 1.25 kΩ ±5%.
- Locked Coil Inductance: 125 mH, typical.
- Operating and Storage Temperature: -29°C to +121°C (-20°F to +250°F).
- Relative Humidity: Up to 95% noncondensing; 100% non-submerged when ordered with integral cable.
- Case Material: Anodized aluminum A204.
- Gasket Material: Neoprene.
- Height: 102 mm (4 in) typical (depending on connector option).
- Diameter: 41 mm (1.6 in) typical.
- Weight: 300 grams (10.5 ounces) typical.
One standout spec is the 20 mV/mm/s sensitivity. This ensures clear signals even from subtle vibration changes, allowing early intervention before minor issues escalate.
Installation and Mounting Guidance
Proper installation is critical for accurate readings. The 9200-09-01-01-00 comes with a top mount connector option (no cable) and a circular mounting base with a 1/4-20 UNC stud. This configuration simplifies secure attachment to the machine casing.
For best results, mount the transducer at the specified angle (0 ±180) and ensure the calibration load is 10 kΩ across terminals A and B. Always follow the manufacturer's manual for torque specifications and surface preparation.
Maintenance and Reliability Tips
Regular inspection helps maintain long-term performance. Because the unit is dust and moisture resistant, it suits harsh environments. Check the mounting integrity periodically and verify the output signal against a known reference.
Temperature extremes can affect sensitivity (temperature coefficient 0.2%/°C), so account for ambient conditions when interpreting data. With proper care, this transducer provides consistent, reliable service.
Compatibility and Integration
The 9200-09-01-01-00 is a two-wire transducer, which simplifies wiring to most monitoring systems. It is designed to work with Bently Nevada monitoring equipment, but its standard output makes it adaptable to many data acquisition systems.
For integration questions, consult the official Bently Nevada documentation or contact AutoDCSTech for guidance.
Common Issues and Troubleshooting
If readings seem erratic, first verify the load resistance is exactly 10 kΩ. Incorrect termination can cause sensitivity errors. Also, check that the transducer is oriented at the calibration angle; deviations affect output.
Inspect the mounting stud for looseness, as vibration can gradually loosen fittings. If the signal drops, test coil resistance (should be 1.25 kΩ ±5%) to confirm the coil is intact.
Product Support and Availability
The 9200-09-01-01-00 is available as new and original in factory packing. AutoDCSTech supplies this transducer with a 12-month factory warranty. For current lifecycle status and ordering details, contact AutoDCSTech directly.
