ISC40G (S) -GS Inductive Conductivity Sensor

Brand: Yokogawa Electric Corporation

The model ISC40 sensors are designed for use with our 2-wire analyzers and 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 harsh 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 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.
Features
  • Inductive Conductivity technique for elimination of fouling and polarization errors.
  • Wide bore sensors for long term stability.
  • Installation flexibility by wide range of holders and by the use of universal bulkhead construction.
  • Wide rangeability in terms of conductivity (1 μS/cm to 2 S/cm) and temperature (-20° to 130° C).
