Core Function:
Extended-range eddy current sensor for large-displacement monitoring in industrial applications.

Key Specifications:
• Sensitivity: 1.1 mV/µm (±5%)
• Wide Measurement Range: 0-10mm (10,000µm)
• Frequency Response: DC to 10kHz
• Output: -2 to -20V DC

Robust Design:
✓ 8mm probe diameter
✓ M10×1 threaded mounting
✓ -40°C to +150°C operation
✓ 4MPa pressure rating

Measurement Performance:

Default calibration for AISI 4140 steel

Linear range: 3-7mm (60% of full scale)

Typical accuracy: ±1% FS

System Integration:
• Compatible with EPRO MMS6000 systems
• Requires signal conditioning for optimal performance
• 5m high-temp cable (standard)

Typical Applications:

Large turbine shaft monitoring
