The 177230-01-02-CN Bently Nevada Vibration Transmitter is a loop-powered seismic transmitter for PLC/DCS integration. It measures vibration from 3 Hz to 1 kHz with 0-25.4 mm/s range, featuring ceramic shear sensing and self-test capability.
Control&Communication
Product Type: Loop-powered seismic transmitter for integration with PLC, DCS, and SCADA control systems.
Measurement Range: 0 to 25.4 mm/s (0 to 1.0 in/s) velocity with frequency response of 3 Hz to 1 kHz (180 to 60,000 cpm).
Output Signal: Industry-standard 4-20 mA loop-powered interface requiring no field configuration or adjustments.
Sensing Element: Ceramic shear-type sensing element with transverse sensitivity less than 5% of sensitivity.
Performance Specifications: Settling time less than 15 seconds within 2% of final value; mounted resonant frequency greater than 12 kHz.
Installation Features: Protected interface, self-test capability, supports multiple cable types, and minimal additional parts required.
Specific Application
- Distributed velocity vibration tracking on small auxiliary machinery blocks via direct loop routing into standard industrial PLCs or DCS racks.
- Machinery condition monitoring optimization on high-speed components requiring peak vibration metric data scaling rather than broadband RMS logging.
- Dual-purpose monitoring deployments demanding simultaneous 4-20 mA process loop trends alongside raw unbuffered acceleration spectrum signals for analysis.
System Compatibility and Alternative Models
- System Compatibility: Interfaces directly with programmable logic controllers (PLCs), distributed control systems (DCS), and SCADA platforms supporting 12 to 30 Vdc internal excitation loops current-limited to 40 mA. Uses a 3-pin MIL-C-5015 connector mating with standard unarmored (16925) or armored (16710) Bently Nevada interconnect cables.
- Alternative Model: 177230-01-01-05 Seismic Transmitter.
- Key Differences:
Frequency Response Parameter: The 177230-01-02-CN utilizes a 3 Hz to 1 kHz spectrum tracking peak vibration levels, whereas the 177230-01-01-05 operates over a 10 Hz to 1 kHz range proportional to broadband RMS levels.
Agency Approvals: The custom suffix "-CN" denotes regional certifications for the Chinese industrial market, while the standard "-05" suffix represents multiple global certifications combining North American (CSA) and international (ATEX/IECEx) hazardous area standards.
