General Model ISC40 Specifications Inductive Conductivity sensor and fittings The model ISC40 sensors are designed for use with the EXA: ISC202g(S) 2-wire transmitters and the EXA: ISC450G 4-wire analyzers. This combination exceeds all expectations for conductivity measurement in terms of: reliability, accuracy, rangeability and price performance. The accuracy is 0.5% of reading plus 0.5 uS/cm for any conductivity value: whether measured in rinse water or in concentrated acids. The materials of construction guarantee a long life under harch industrial conditions: - The erosion/abrasion resistant PEEK (Poly Ether Ether Ketone), which also features excellent chemical resistance in all solutions except fluoric acid or oxidizing concentrated acids. - The ultimate material in terms of chemical resistance: PFA for applications in hydrofluoric acid and oxidizing concentrated acids (nitric, sulfuric, oleum). The PEEK sensor is provided with a rugged Stainless Steel mounting thread, nut and gasket combination for ultimate flexibility in installation using bulk head installation technique. There is also a wide range of holders and options available for reliable in-line or off-line installation with double O-ring seals for long service life of the sensor. Additional models are available for use in Ball-Valve Insertion applications and in Sanitary Flange installations. The PFA sensor comes with an integral lap-joint flange, because in applications, where this sensor is used, it is very difficult to find O-rings that are resistant to the process. Both sensors have a large bore for optimal resistance to fouling processes and when properly installed, the flow will keep the Features and Applications sensor clean preventing measuring errors. • Inductive Conductivity technique for elimination of fouling
