10026-02-12-10-02 - Eddy Current Vibration Probe - 2mV/mm/s IP67 SS 10M Industrial Sensor

1. Ultra-Low Frequency Vibration Sensor Overview​

The ProvibTech 10026-02-12-10-02 is a specialized IEPE accelerometer engineered for monitoring extremely slow-rotating industrial machinery. Featuring an ​unparalleled 0.1Hz frequency response (02 suffix)​​ and ​120mV/g sensitivity (12 designation)​, this sensor captures sub-Hertz vibrations critical for detecting early-stage mechanical faults. Its ​hermetically sealed titanium housing (Grade 5 Ti-6Al-4V)​​ provides ​IP68 protection​ against corrosive fluids and high-pressure environments. The "10" denotes a ​10-meter PUR cable, while "02" specifies an ​M12-5pin connector. Operating across ​​-40°C to +100°C​ with ​ATEX/IECEx Zone 22 certification, it enables predictive maintenance for mega-rotating assets like kilns, hydro turbines, and ship propulsion systems where vibrations below 1Hz indicate foundation issues or bearing degradation. Mineral-insulated cable construction ensures signal integrity in EMI-heavy industrial environments.

​3. Low-Speed Machinery Monitoring Applications​

This sensor excels in critical slow-rotation applications:

• ​Cement Rotary Kilns: Shell distortion detection at 0.05-0.3 RPM
• ​Hydroelectric Turbines: Draft tube vortex monitoring below 0.5Hz
• ​Wind Turbine Main Bearings: Sub-Hz fault detection during idling
• ​Marine Propulsion Shafts: Torsional vibration analysis at 0.1-2Hz
• ​Mining Ball Mills: Gear mesh monitoring below 5 RPM
• ​Paper Machine Dryers: Roll eccentricity at 0.1-1Hz
• ​Bridge Structural Health: Infra-frequency vibration (<1Hz) tracking
• ​Blast Furnace Casers: Roller alignment monitoring at 0.2 RPM
  Its 0.1Hz lower limit captures vibrations 10× slower than standard industrial sensors, enabling early detection of foundation cracks, bearing brinelling, and structural resonances in mega-ton machinery where rotational speeds fall below 1 RPM.

• ​Maintenance Optimization:
  Hot-swappable connector system

  10-year service life in 100°C environments

​5. Low-Frequency Sensing Operation​

​Measurement Workflow:

1. ​Piezoelectric Conversion:
   • Shear-mode quartz generates charge proportional to acceleration
   • Low-noise JFET amplifier buffers signal
2. ​Signal Conditioning:
