Vaisala MMT330 Moisture in Oil Transmitter

Vaisala MMT330 are a series of moisture in oil transmitters for hydraulic and lubrication systems and transformer oil monitoring.  Unlike a “water cut” meter, Vaisala’s range of moisture in oil devices detect the unsaturated moisture in oil.  This offers improved condition monitoring of your oil, alerting problems before they occur.  Vaisala MMT330 is compliant with DNV GL 2.4 type approval (Class B) and also approved for installation in MAN Diesel & Turbo Two-Stroke Diesel Engines lubrication systems.

 

Efficient monitoring saves both oil and the environment. Vaisala MMT330 makes it simple and economical to monitor the changes of moisture in oil.   The instrument is compatible with Vaisala MM70 Handheld Moisture in Oil Meter for calibration.

There are three instruments in the types to enable various types of installations:

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

 

As of 2021, Vaisala have introduced an Indigo series of transmitters that will eventually replace much of the 330 product family, including the MMT330 range.  Have a look HERE and please consult Fluidic for probe options.
