MMT330 Moisture and Temperature
Transmitter Series for Oil
The Vaisala HUMICAP
®
Moisture and
Temperature Transmitter Series for
Oil MMT330 enables the fast and
reliable detection of moisture in oil.
MMT330 series transmitters can be
used in online moisture monitoring
and as control devices, allowing
separators and oil driers to be
started only when needed.
Proper monitoring saves both oil and
the environment. With the MMT330
series it is easy and economical to
monitor the changes of moisture in
oil.
Reliable Vaisala
HUMICAP® Technology
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 MMT330 transmitter family offers reliable performance for the demanding
measurement of moisture in oil.
The display shows measurement
trends, real-time data, and
measurement history.
The sensor's excellent chemical
tolerance provides accurate and
reliable measurement over a wide
measurement range.
For Diverse Applications
and Demanding
Conditions
With a wide variety of probes, the
transmitter can be used in lubrication
systems, hydraulic systems, and
transformers.
Indicates the Margin to
Water Saturation
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.
