Water in oil compact transmitter - EE381

The EE381 series is specifically designed for monitoring the moisture content in oil in industrial applications. Typically - transformers, hydraulic systems and engines and gearboxes (eg marine). The fundamental measurement is water activity which is a relative measurement from zero (no water ) to 1.000 aw which is fully saturated at that temperature. Increasing the moisture content will result in free water as a suspension or precipitate. This is temperature related, and by measuring temperature, the content of water in ppm can be determined - when the characteristics of the particular oil are known. The output can then be scaled in ppm. There is a portable version in the Omniport range of hand held meters, and the more sophisticated EE36 model with remote probe.
