Vaisala Humicap sensor structure

Uniquely robust sensors

Vaisala’s HUMICAP® were the first ever capacitive sensors used to measure moisture in oil online, and have since become a virtual industry standard. 

The sensors have specifically been developed to measure even very low moisture levels in oils — mineral, vegetable and synthetic. The HUMICAP® sensors, manufactured in Vaisala’s own cleanrooms, have seen use in all corners of the Earth and even Mars.

Get all the gains

Robust reliability

  • Accurate water saturation and PPM measurements in rapidly changing conditions.
  • All equipment comes with NIST or Accredited calibration and is field calibratable.
  • No moving parts in transmitters.

Long-term stability

  • Thin film polymer sensor designs protect from contamination and are highly selective to water  only .
  • Capacitive technology provides long term stable measurement.
  • Insensitive to additives or contaminants in oil.
  • Auto-recovery from full saturation.
  • ...

Rapid Response

  • In situ, real time measurement of moisture in oil as true relative saturation (%RS).
  • Eliminates need for sampling and lab analysis for moisture.
  • Easy installation via ball valve. 
  • Installable even in energized transformers.
