Emerson A6210

Description

Core Functions and Applications

1. Thrust Position Monitoring:
   • Tracks axial shaft displacement in turbomachinery (e.g., turbines, compressors) to prevent rotor-to-case contact.
   • Resolves movements as small as ±0.001 mm, using eddy current sensors to detect sudden shifts that could lead to catastrophic failures.
2. Differential Expansion Monitoring:
   • Measures thermal growth differences between turbine casings and rotors during start-up/shutdown cycles.
   • Supports tandem/complementary or cone/ramp modes to adapt to varying temperature fluctuations in power plants and industrial facilities.
3. Rod Position Monitoring:
   • Detects piston rod wear in reciprocating compressors by monitoring rider band movement.
   • Enables predictive maintenance by alerting operators to early-stage wear, reducing unplanned downtime.

   • Seamless compatibility with Emerson’s AMS 6500 Machinery Health Monitor, DeltaV™, and Ovation™ DCS systems via MODBUS or OPC-UA.
4. Advanced Signal Processing:
   • PeakVue Technology enhances detection of early-stage bearing defects and impacts in noisy environments.
   • Built-in linearization algorithms optimize sensor accuracy post-installation.

Industry Applications

• Power Generation:
  Monitors turbine thrust bearings and differential expansion in coal/gas-fired plants to prevent rotor-stator collisions.
• Oil & Gas:
  Detects rod wear in reciprocating compressors and ensures safe operation of turbomachinery in offshore platforms.
• Manufacturing:
  Tracks piston rod position in injection molding machines and presses to avoid equipment damage.

Competitor Comparison

• Multi-Functionality: Combines thrust, expansion, and rod monitoring in a single module.
• Temperature Range: Operates reliably at 0–65°C, compared to 0–50°C for some competitors.
• Integration: Native compatibility with Emerson’s AMS 6500 system reduces engineering effort.
