Performance Features

Flexible Signal Handling: Each channel can be individually configured via software for voltage or current input, allowing integration with a variety of sensors measuring pressure, flow, temperature, or level.

High-Resolution Conversion: 14- to 16-bit A/D converters ensure precise measurement of small signal variations for accurate turbine control.

Real-Time Processing: Capable of sampling all channels at high speed to meet the demands of critical turbine monitoring applications.

Fault-Tolerant Design: Fully supports TMR architectures, ensuring the highest level of reliability in safety-critical applications.

Diagnostic Capability: Continuous monitoring detects open circuits, out-of-range signals, and internal faults, with status reported to the control system.

Electrical Protection: Robust isolation protects the VME bus from electrical surges and electromagnetic interference from turbine hall environments.

Applications

  • Pressure Monitoring: Fuel, lube oil, and compressor discharge pressures.

  • Flow Measurement: Fuel and cooling water flows.

  • Valve Position Tracking: Interfaces with LVDTs/RVDTs for servo-valve position feedback.

  • Level Sensing: Monitors tanks for water-wash and oil-sump systems.
