Keep your plant's most critical rotating equipment safe and running smoothly. The Speed and Key Monitor tracks speed, phase, zero speed, and rotation direction, providing high-reliability monitoring for steam, gas, compressors, and hydro turbines.
Built for Redundancy
Worried about downtime? This monitor can run in redundant mode, automatically switching from primary to backup tachometers when needed. It monitors sensor gap voltage and pulse counts to ensure seamless switchover. For accurate phase continuity, both main and failover sensors must be aligned in the same axial plane.
Smart Speed & Phase Tracking
Speed Measurement: Uses a displacement sensor with targets like toothed wheels, keyways, or gears. Provides alarms for zero speed, detects reverse rotation, and feeds data for advanced process analysis.
Phase (Key) Measurement: Requires a once-per-revolution target to accurately track machine health changes. A key parameter for predictive maintenance programs.
