MS2100 is a fast, reliable and accurate on-line detection system for water in organic liquids, oil, etc.

Low limit moisture on-line test has been always troubles in some crisis industry process. Both of on-line and laboratory analyzers are expensive, and time costing in the past time.

It was  hoped to replace some process instruments at certain cases, to save lots of equipment investment and maintenance cost. What is most important is it's easy way to test directly and real time response, and also excellent accuracy. Speed is very important in modern chemical process. 

The system measure water activity, water content/moisture, separation point (equal to dew point in air moisture), and temperature as well. With T-BD5xMD STIM, all these parameters can be displayed at field, and could be read by NCAP controller in remote area. The analog signal output port of the transmitter could be set to output one of these parameters, such as water activity, moisture or separation point by user selection.

Water Activity is a relative parameter for moisture. In some application, it is more obvious than traditional absolute terminology, for it is directly meaning the possibility to happen of water separation. Water formation is often critic accident for processes. 

Separation Point is one concept determined by our institute. Thought it is not so concerned as Dew Point, but also convenient for some applications. For it is more easy to compare the separation point with the sample temperature, so that to estimate the risk of the system by operators. 

As to application for transformer oil, water activity measurement offers several advantages compared to the traditionally measured variable, parts per million (ppm). Water activity indicates directly whether there is risk for free water formation. The measurement is 97% independent of the oil type, aging , and compensated by temperature algebra.
