Bently Nevada 2201/02-01 N3 Seismic Transmitter
The Bently Nevada 2201/02-01 N3 is a precision seismic velocity transmitter that converts mechanical vibration into industry-standard 4-20mA current loop signals. Engineered for continuous machinery health monitoring, this transmitter delivers reliable performance in the harshest industrial environments.
Core Specifications
- Model Number: 2201/02-01 N3
- Output Signal: 4-20mA current loop
- Measurement Type: Velocity (in/sec or mm/sec)
- Frequency Range: 10 Hz to 1000 Hz
- Sensitivity: 100 mV/in/sec nominal
- Power Supply: 18-30 VDC loop-powered
- Operating Temperature: -40°C to +85°C
- Mounting: 1/4-28 UNF stud mount
- Enclosure Rating: IP67 sealed construction
Why Choose the 2201 Series?
Q: What makes this transmitter different from standard accelerometers?
A: The 2201/02-01 N3 integrates signal conditioning directly into the sensor housing, eliminating the need for external proximitors or signal conditioners. This reduces installation complexity, lowers system cost, and improves reliability by minimizing connection points.
Q: Where is this transmitter typically installed?
A: Common applications include motor bearing housings, pump casings, fan pedestals, gearbox housings, and compressor frames—anywhere you need continuous vibration monitoring with simple two-wire connectivity to PLCs, DCS systems, or portable data collectors.
Q: Can it survive harsh industrial conditions?
A: Absolutely. The hermetically-sealed stainless steel housing withstands moisture, oil contamination, temperature extremes, and mechanical shock. It's designed for permanent outdoor installation in refineries, chemical plants, power stations, and marine environments.
Real-World Problem Solving
Maintenance teams face a constant challenge: detecting bearing failures before catastrophic breakdowns occur. The 2201/02-01 N3 provides early warning by continuously measuring vibration velocity—the most sensitive indicator of bearing wear, imbalance, misalignment, and looseness.
When vibration levels exceed normal operating ranges, the 4-20mA output triggers alarms in your control system, allowing planned maintenance instead of emergency shutdowns. This predictive approach reduces downtime by 30-50% and extends equipment life significantly.
Integration & Compatibility
The current loop output connects directly to:
- PLC analog input modules (Allen-Bradley, Siemens, Schneider)
- DCS systems (Honeywell, Emerson, ABB)
- Vibration monitors and trip modules
- SCADA systems and data historians
- Portable vibration analyzers for route-based monitoring
No special interface cards or proprietary protocols required—just standard industrial wiring practices.
Installation Best Practices
Mount the transmitter as close as possible to the bearing housing using the included mounting stud. Ensure the mounting surface is flat, clean, and rigid. Route the two-wire cable through conduit to your control panel, observing proper grounding and separation from high-voltage power cables to minimize electrical noise.
Product Condition: Brand new, factory-sealed with calibration certificate and full manufacturer warranty.
