Application Scenarios
The 3500/40M module is essential for protecting machinery from temperature-related failures across various industries.
Turbine and Compressor Protection:
Monitors radial and thrust bearing temperatures on steam turbines, gas turbines, and centrifugal compressors to prevent catastrophic bearing failure due to overheating.
Electric Motor Monitoring:
Tracks stator winding and bearing temperatures in large high-voltage motors, providing early warning of insulation breakdown or lubrication failure.
Pump Systems:
Monitors bearing temperatures on critical pumps in power generation, oil and gas, and water treatment facilities to schedule maintenance and avoid unexpected downtime.
Gearbox Monitoring:
Monitors bearing and oil sump temperatures in large gearboxes to detect issues related to overloading, lubrication failure, or component wear.
Machine Health Integration:
Provides a unified protection system within the 3500 rack by integrating temperature data with vibration and speed information, allowing for comprehensive machine health assessment and complex alarm logic.
