Experience. That’s Vaisala. With some 50 years in developing and manufacturing capacitive moisture sensors for gas and oil, Vaisala has become the veritable standard and the market leader.
Expertise. That’s Vaisala. From power transformers to lubrication systems, and from maritime to pulp and paper Vaisala leads the leap into knowledge. With sensors built-in our own cleanrooms our robust technology offers long term stable and precise measurements.
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.
Real-time measurement of relative saturation (%RS) e.g. for dielectric strength monitoring
Effect of relative moisture saturation (%RS) on dielectric strength of transformer insulation oils is visible in the picture on right.
