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.
Vaisala HUMICAP® Moisture in Oil Probe MMP8 enables fast and reliable measurement of moisture in oil.
The MMT330 series enables fast and reliable detection of moisture in oil in central lubrication systems, hydraulic systems and power transformers. Three probe options offer solutions for various installation requirements, like high pressure, tight spaces and pipeline installations. The series is also compliant with DNV GL 2.4 type approval (Class B).
Excellent economical solution for reliable on-line detection of moisture in oil even in the most demanding applications. The sensor’s excellent chemical tolerance provides accurate and reliable measurement over the measurement range.
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. Excellent pressure and temperature tolerance.
Vaisala HUMICAP® Moisture and Temperature Transmitter Series MMT310 is a fast and reliable on-line detector for moisture in oil. Used in for applications such as e.g. monitoring of transformer oil and of lubrication systems in marine and paper industry.
