The Vaisala Moisture and Temperature Transmitter Series for Oil MMT330
Applications
The MMT330 series incorporates the latest-generation Vaisala HUMICAP® sensor, which is the result of over 15 years of field experience. It was developed for demanding moisture measurement in liquid hydrocarbons. The sensor’s excellent chemical tolerance provides accurate and reliable measurement over a wide measurement range.
With a wide variety of probes, the transmitter can be used in lubrication systems, hydraulic systems, and transformers.
The MMT330 measures moisture in oil in terms of the water activity (aw) and temperature (T). Water activity indicates directly whether there is a risk of free-water formation. The measurement is independent of oil type and age.
The MMT330 features a large numerical and graphical display with a multilingual menu and keypad. It allows users to easily monitor operational data, measurement trends, and access measurement history for the past 12 months.
