The Emerson A6370D Overspeed Protection Monitor is a critical safety component designed for high-speed rotating machinery protection in industrial applications.
1. Key Functions
Overspeed Detection:
Monitors rotational speed (RPM) using eddy current, Hall-effect, or magnetic (VR) sensors, triggering alarms/trips when thresholds are exceeded.
Redundant Safety Design:
Part of the AMS 6300 SIS (Safety Instrumented System), typically deployed in a triple-redundant configuration (3x A6370D modules) for fail-safe operation.
Sensor Compatibility:
Supports multiple sensor types with -24.5V DC excitation (eddy current/Hall) or 1–30V RMS input (magnetic VR sensors).
Integration:
Interfaces with Bently Nevada 3500/System 1™ for condition monitoring and predictive maintenance.
2. Technical Specifications
Input Range:
Eddy Current/Hall Sensors: 0–26V DC (48V max withstand).
Magnetic VR Sensors: 1 Vpp to 30V RMS.
Frequency Range: 0–20 kHz.
Outputs: Relay contacts (trip/alarm) and 4-20mA signals for DCS integration.
Certifications: Complies with SIL 2/3 for safety-critical systems.
3. Applications
Power Generation: Gas/steam turbine overspeed protection (API 670).
Oil & Gas: Compressor and pump safety systems.
Industrial: Critical machinery requiring SIL-rated protection.
