B&K Vibro VC-1100 C11 – Bearing Vibration Monitoring Sensor | Condition Monitoring Platform
Engineering Background
Brüel & Kjær Vibro (B&K Vibro) is a globally recognized leader in machine condition monitoring and protection systems, with decades of deployment across power generation, petrochemical, marine, and heavy industrial sectors. The VC-1100 series represents the company’s precision-grade vibration transducer platform, engineered for continuous bearing health surveillance in rotating machinery.
Product Positioning
The VC-1100 C11 is a high-sensitivity bearing vibration monitoring sensor designed for integration into both standalone condition monitoring systems and distributed plant-wide CMS networks. It delivers reliable, low-noise vibration signals from rolling-element bearings, enabling early fault detection and predictive maintenance scheduling — critical for minimizing unplanned downtime in asset-intensive operations.

System Architecture & Signal Flow
The VC-1100 C11 operates as a field-mounted transducer within a layered condition monitoring architecture:
- Sensor Layer: VC-1100 C11 mounted on bearing housing → captures raw vibration acceleration signal
- Signal Conditioning: IEPE constant-current excitation supplied by monitoring module (e.g., VC-8000 I/O card or third-party IEPE conditioner)
- Processing Layer: Monitoring system performs RMS, peak, envelope (bearing-band), and spectral analysis
- Alarm & Trending: Alert/danger thresholds trigger DCS/PLC outputs; trend data logged to historian or CMMS
- Reporting: Maintenance teams receive actionable bearing health KPIs — ISO 10816 / ISO 20816 compliant reporting

Technical FAQ
Q: Is the VC-1100 C11 compatible with third-party CMS platforms?
A: Yes. The IEPE/ICP® output standard is universally compatible with any monitoring system that provides constant-current excitation (typically 2–20 mA at 18–30 VDC). Confirm input impedance and excitation current with your system supplier.
Q: What is the difference between the C11 and other VC-1100 variants?
A: The C11 suffix designates the mounting and connector configuration. Contact Konmask to confirm the exact variant matches your mechanical interface and cable routing requirements.
Q: Can this sensor be used in ATEX/hazardous area zones?
A: ATEX-rated configurations of the VC-1100 series exist. Confirm the specific Ex certification (zone, gas group, temperature class) required for your installation before ordering.
Q: What is the typical lead time?
A: In-stock units ship within 2–5 business days. For out-of-stock items, lead time is 2–6 weeks depending on sourcing channel. Contact us for real-time availability.
Q: Do you provide calibration certificates?
A: Original factory calibration documentation is provided where available. Third-party calibration can be arranged upon request at additional cost.
