VAISALA MOISTURE IN OIL MMT330

VAISALA MOISTURE IN OIL MMT330

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.

• Three probe types for various installation requirements:

MMT332 for high pressure installations
MMT337 for tight spaces with a thread connection
MMT338 for pipeline installations

• Continuous online 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 measurement history
• LAN and WLAN communication options
• NIST traceable calibration (certificate included)
