New Intelligence for Measuring Moisture in Oil from Vaisala.

Vaisala introduces the new Vaisala HUMICAP® Moisture and Temperature Transmitter Series for Oil MMT330. The series provides fast, reliable, and accurate on-line measurement of moisture and temperature in oil.

Moisture measurement for oil can considerably decrease maintenance costs and prolong the service lifetime of machines. The main applications for the MMT330 are the moisture measurement of lubrication, hydraulic fluid and transformer oils.

The MMT330 measures water activity and temperature in oil. The water activity measurement in oil offers several advantages compared to the traditional ppm-measurement. The MMT330 provides reliable information on how close the oil is to its saturation point, i.e. the formation of free water. Oil-specific calibration is not necessary, as water activity is not affected by the type or age of the oil. Moreover, the transmitter can be ordered with a ball valve set, allowing installation and removal of the probe for calibration without draining the oil system.

The MMT330 can be ordered with a large numerical and graphical display with a multilingual menu. With the new probe options the operating pressure range has been expanded to 250 bars. Data logging capability and the ability to download to a PC allow the user to monitor measurement trends and up to one year of historical data. Due to full compatibility with the Vaisala HUMICAP® Hand-Held Moisture in Oil Meter MM70, field-checking, maintaining, and calibrating the MMT330 is easy.
