⚙️ Emerson 1C31181G04 Ovation Speed Detector Module
Real-time rotational speed monitoring for turbomachinery, compressors, and motor-driven equipment. The 1C31181G04 speed detector module converts magnetic pickup, proximity probe, or encoder signals into accurate RPM data for Emerson Ovation distributed control systems.
🎯 Precision Speed Measurement
This module processes pulse trains from speed sensors mounted on rotating shafts, gear teeth, or encoder wheels. Advanced signal conditioning filters mechanical noise and electrical interference, delivering clean frequency data that the DCS converts to engineering units—RPM, Hz, or rad/s—with ±0.01% accuracy.
🏭 Industrial Applications
- Turbine Monitoring: Steam and gas turbine overspeed protection in power generation plants
- Compressor Control: Anti-surge and capacity control for centrifugal compressors in petrochemical facilities
- Motor Protection: Detect bearing failures, coupling misalignment, and rotor imbalance before catastrophic damage
- Process Optimization: Variable-speed drive feedback for pumps, fans, and agitators in batch and continuous processes
🔧 Technical Specifications
| Input Types | Magnetic pickup, proximity probe, TTL encoder |
| Frequency Range | 0.1 Hz to 20 kHz (configurable) |
| Accuracy | ±0.01% of reading |
| Update Rate | 100 ms (configurable down to 10 ms) |
| Isolation | 1500 VAC channel-to-logic |
| Diagnostics | Sensor fault, signal loss, out-of-range alarms |
💡 Smart Diagnostics & Safety
Predictive Maintenance: Trend speed deviations over time to schedule bearing replacements before unplanned shutdowns.
Overspeed Shutdown: Configurable high-speed trip points trigger emergency stops, protecting equipment from runaway conditions per API 670 standards.
Redundancy Ready: Dual-channel configurations with voting logic ensure continuous operation even if one sensor fails.
✅ Why 1C31181G04?
Proven in Critical Service: Deployed in refineries, LNG terminals, and chemical plants where speed measurement integrity is mission-critical.
Seamless Integration: Native Ovation protocol—no third-party gateways or protocol converters required.
Field-Proven Reliability: MTBF >200,000 hours; SIL 2 capable when configured per IEC 61508.
📦 Package Contents
1C31181G04 speed detector module, installation guide, calibration certificate. Sensors and mounting hardware sold separately.
Protect your rotating assets with the 1C31181G04—engineered for the precision demands of modern process control.
