ISC40G(S)

Overview

Inductive conductivity sensors and fittings

Product Description

The model ISC40 sensors are designed for use with the EXA:
ISC200 2-wire transmitters and the EXA: ISC402 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/ 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 sen-sor clean preventing measuring errors.


FEATURES AND APPLICATIONS

  • 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 130ºC).
  • All applications where severe electrode fouling prevents the use of contacting electrodes.
  • All ranges except the (ultra) pure water applications.
  • All slurry applications where conventional systems suffer from plugging or erosion.
  • All applications where the 6 decade rangeability is necessary for accurate process control.
