2300 Series — hydro turbine monitoring

Description

2300 Series is a specialized condition monitoring system for hydro turbines and hydrogenerators. The system is engineered for hydro power requirements, including high humidity and unique hydro unit parameters.

Key features

Hydro turbine specialization

• Turbine shaft monitoring - radial vibration, axial position
• Guide bearings - vibration and temperature
• Turbine bearings - comprehensive monitoring
• Gaps and displacements - working gap control

Measured parameters

• Shaft vibration (radial, axial)
• Bearing vibration (absolute, relative)
• Bearing temperature
• Seal gaps
• Runner position

Outputs and integration

• 4–20 mA outputs for control systems
• Relay outputs for emergency alarming
• Modbus for SCADA integration
• Ethernet for network integration

Environmental resistance

• Moisture protection - high IP protection rating
• Condensation resistance - operation in high humidity
• Industrial temperature range - from -40 to +70°C

Applications
