Thrust Position Monitor A6210 | Emerson CSI AMS 6500

Emerson CSI A6210 Thrust, Expansion, and Rod Position Monitor

The Emerson A6210 is a versatile dual-channel monitor for the AMS 6500 system. It operates in three key modes: thrust position, differential expansion, and rod drop measurement. This API 670 and API 618 compliant module provides critical protection for turbines and compressors by detecting axial movement and wear.

FAQ

• What are the three main measurement modes?
  Thrust Position (axial shaft movement), Differential Expansion (case vs. rotor growth), and Average Rod Drop (piston wear in compressors).
• Is this monitor suitable for safety-critical applications?
  For SIL 3-rated applications, the Emerson A6250 monitor is recommended. The A6210 is API compliant for general machinery protection.
• What is the 'Limit Multiply' function used for?
  It allows remote adjustment of alarm setpoints by a multiplier, useful for testing or different operating conditions.
