Pure Water (Low) Conductivity sensors SC4A(J)/SC42

The measurement of specific conductivity in aqueous solutions is becoming increasingly important for the determination of impurities in water. The accuracy of the measurement is strongly influenced by temperature variations, polarization effects at the surface of the contacting electrodes, cable capacitances, etc. Yokogawa has designed a full range of precision sensors and instruments to cope with these measurements, even under extreme conditions.

These groups of sensors are intended for the low conductivity applications found in the semi-conductor, power, water and pharmaceutical industries, these sensors are in a convenient compact style. There are several mounting possibilities one of which is mounting by a compression gland, giving a simple effective method of direct insertion in process pipework.

The sensors are made from a combination of wetted materials approved by FDA. This makes them ideally suited for the monitoring of pure water systems used in the preparation of injectable solutions and the like, for this kind of application, sanitary clamp mountings are used.

Overview:

There are a number of suppliers of oil and fat products used for edible purposes. These products include, but are not limited to olive oil, peanut oil, soybean oil, sunflower oil, lard, shortening, butter, and margarine. The raw materials for these products include animal by-products, fleshy fruits (palm and olive), and oilseeds. 

Industry:Food and Beverage

Application Note
Overview:

To defray energy costs, many industrial plants have their own boilers to generate steam to produce a portion of their energy needs. In addition to generating power, the steam may also be used directly in plant processes or indirectly via heat exchangers or steam jacketed vessels.
