Product Application Fields
- Steam & Gas Turbines: Critical overspeed protection and rotational speed synchronization.
- Large Centrifugal Compressors: Continuous RPM monitoring and vibration-correlated speed analysis.
- Pump Stations: Zero-speed detection and reverse rotation monitoring in water and oil transport.
- Industrial Fans & Blowers: Managing fan speed for efficiency and preventing mechanical resonance.
Product Q&A
Q1: Can the MMS6312 be used for safety-critical overspeed protection? A1: Yes, the MMS6312 is specifically designed for high-integrity protection loops and is often configured in redundant architectures for SIL-rated safety systems.
Q2: What types of speed sensors are compatible with this module? A2: It supports a wide range of inputs, including passive magnetic pickups (MPUs), active Hall-effect sensors, and eddy current displacement probes (e.g., PR6423).
Q3: How is the module configured for a specific RPM range? A3: Configuration is performed via the EPRO MMS6000 software interface, where users can set the number of teeth on the trigger wheel, scaling for the 4-20mA output, and alarm thresholds.
