The MMT162 enables on-line moisture monitoring in oils even in the most demanding applications.

In transformer applications ppm-units are traditionally used. It indicates the average mass concentration of water in oil. he ppm calculation for mineral oil based transformer oil is optional in the MMT162.

Lubrication systems, hydraulic systems and transformers are among the typical applications of the MMT162. Its measurements can be used for on-line moisture monitoring and as a control function, allowing dryers and oil purifiers to be started only when necessary.

he MMT162 has two analog

outputs that can be scaled and the measurement ranges changed. Additionally, the transmitter has an RS-485 serial output. he signals and the unit power travel in the same cable.

he Vaisala HUMICAP' Moisture and Temperature Transmitter for Oil MMT162 is an excellent economical solution for reliable on-line detection of moisture in oil.

he MMT162 incorporates the latest generation of the Vaisala HUMICAP' Sensor. he sensor is developed for demanding moisture measurement in liquid hydrocarbons and has been successfully used in oil applications for over a decade. he sensor's excellent chemical tolerance provides accurate and reliable measurement over the measurement range.

he MMT162 measures moisture in oil in terms of the water activity (aw) and temperature (T). Water activity directly indicates whether there is a risk of free water formation. he measurement is independent of oil type, age and temperature.

An optional LED-cable enables a visual alarm.

Due to its compact size, the MMT162 is quickly and easily installed in tight spaces. Units are delivered fully assembled, however, you can re-conigure them to suit your needs.

In combination with an MM70 indicator, the MMT162 provides an ideal tool for on site calibration. he MI70 indicator can be used as a display, communication, and data-login device

for the MMT162.
