10026-02-12-05-02 - Eddy Current Vibration Probe - 2mV/mm/s IP67 SS Industrial Sensor

1. Low-Frequency Vibration Sensor Overview​

The ProvibTech 10026-02-12-05-02 is a specialized IEPE accelerometer engineered for low-frequency vibration monitoring in heavy industrial applications. Featuring an ​ultra-low 0.1Hz frequency response (02 suffix)​​ and ​120mV/g sensitivity (12 designation)​, this sensor captures subtle vibrations in slow-rotating machinery with ​​±2% accuracy. Its ​hermetically sealed titanium housing​ provides ​IP68 protection​ against dust, moisture, and temporary submersion (3m depth). The "05" suffix denotes a ​5-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 turbines, mills, and large gearboxes where sub-1Hz vibrations indicate critical faults like foundation settling or misalignment in power generation, mining, and marine industries.
