overview：
Emerson A6312/06 Speed and Key Phase Monitor is designed for critical rotating machinery applications such as steam, gas, compressors and turbines. It is mainly used in conjunction with the AMS 6500 monitor to build a comprehensive API 670 machinery protection system. It can monitor the speed, phase, zero speed and rotation direction of rotating machinery. In redundant mode, the primary and backup sensors must be installed in the same shaft plane to maintain phase continuity. Speed measurement uses a displacement sensor with a gear as the target, and key phase measurement requires a target per revolution.
Fuctions & Features:
- Application: Designed for monitoring speed, phase, zero speed and direction of rotation of rotating machinery.
- Phase Continuity: In redundant mode, the primary and backup sensors must be mounted on the same shaft plane to maintain phase continuity.
- Displacement Sensors: Speed measurements use a displacement sensor with a gear or gear as a target, while keying or phase measurements require a once-per-revolution target.
- Predictive Tools: AMS software provides maintenance personnel with advanced diagnostic tools for early detection of machine failures.
Specifications:
- Number of Inputs: Two independent inputs.
- Input Type: Eddy Current, Differential.
- Isolation: Electrically isolated from power supply.
- Input Voltage Range: 0 to ±27.3 VDC.
- Input Frequency Range: 0 - 20,000 Hz, up to 65,535 RPM.
- Module Size: Dual channel, 3U size module (vs. traditional 6U four channel module)
- Hot Swappable: The module is API 670 compliant and can be replaced without shutting down the system.
- Proportional Output: Post-buffered proportional output (0/4-20 mA).
- Mounting: The module is designed for use in the AMS 6000 (6TE wide) and AMS 6500 (8TE wide) 19-inch rack mount chassis.
