Vaisala MMT330 Series Moisture and Temperature Transmitters for Oil

The Vaisala HUMICAP® Moisture and Temperature Transmitter Series for Oil MMT330 enables fast and reliable detection of moisture in oil. The MMT330 can be used in on-line moisture monitoring and as a control device, allowing separators and oil driers to be started only when needed.

Proper monitoring saves both oil and the environment. With the MMT330 it is easy and economical to monitor the changes of moisture in oil.

Reliable Vaisala HUMICAP® Technology
The MMT330 incorporates the latest generation of the Vaisala HUMICAP® Sensor, which is the result of 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.

For Diverse Applications and Demanding Conditions
Because of the 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 also independent of oil type and age.

• Three probes for moisture in oil measurements (MMT332 for high pressure installation, MMT337 with optional Swagelok connector, is ideal for tight spaces with a thread connection, and MMT338 for pipeline installations)
• Continuous on-line measurement of moisture in oil
• Ball valve installation – no need to shut down the process
• Incorporates Vaisala HUMICAP® Sensor – excellent long-term stability
• Integrated data logging, with over four years of measured history
• LAN and WLAN communication options
• Successor of the HMP228 Moisture and Temperature Transmitter for Oil
