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. READ MORE ABOUT HUMICAP®
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.
