- Vibration Measurement: Accurately translates radial vibration into a standardized current signal.
- Long-Term Stability: Designed for minimal drift over extended operational periods.
Application Scenarios
Applied across various heavy industries for monitoring the mechanical health of turbines, compressors, and large motors.
Performance Parameters
- Scale Factor: 200 mV/mil
- Current Loop Range: 0-4 mils pp = 4-20 mA
- Proximity Range: 10 – 65 mils
Material Composition
Industrial-grade electronic materials and precision mechanical components.
Structural Characteristics
Compact form factor with standardized mounting interfaces.
Working Principle
Demodulates the high-frequency signal from the proximity probe and generates a proportional 4-20 mA output representing the vibration peak-to-peak value.
Installation Requirements
Install in a dry, non-corrosive environment. Use shielded cabling to maintain signal integrity.
Usage Precautions
Verify the scale factor and loop range match the DCS configuration before commissioning.
