Experience. That’s Vaisala. With some 50 years in developing and manufacturing capacitive moisture sensors for gas and oil, Vaisala has become the veritable industry standard and the market leader in protecting critical equipment, from heavy machinery to hydraulic systems to power transformers.
The definitive eBook on the subject, this companion to our renowned webinar series is full of the latest practical and scientific advice on measuring moisture in power transformers.
Real-time measurement of relative saturation (%RS) e.g. for dielectric strength monitoring
Picture: Effect of relative moisture saturation (%RS) on dielectric strength of transformer insulation oils.
From power transformers to lubrication, 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.
Smart and robust. That’s Vaisala MMP8. Powered by the Vaisala HUMICAP® sensor technology, it has become a virtual standard in its field.
Vaisala HUMICAP® Moisture and Temperature Transmitter MMT330 series enables fast and reliable detection of moisture in oil in central lubrication systems, hydraulic systems and power transformers.
Excellent economical solution for reliable on-line detection of moisture in oil even in the most demanding applications.
Reliable MM70 is an ideal tool for the preventive maintenance of oil-filled systems. The water activity measurement indicates the margin to free water formation, which causes severe problems in lubrication systems.
Vaisala HUMICAP® Moisture and Temperature Transmitter Series MMT310 is a fast and reliable on-line detector for moisture in oil.
The intrinsically safe HMT370EX is the ideal solution for use in hazardous areas up to zone 0 and 20.
