ISC40SJ Inductive Conductivity Sensor

Brand: Yokogawa Electric Corporation

The ISC40SJ sensors are designed for use with the FLXA202/FLXA21 2-wire Analyzer, ISC202 2-wire transmitter and the ISC450G 4-wire converter. 

This combination exceeds all expectations for conductivity measurement in terms of reliability, accuracy, rangeability and price performance.

This innovative inductive conductivity sensor provides highly accurate measurements over a wide measuring range (1 µS/cm to 1999 mS/cm) and process temperature range (-10° to 130° C, -10° to 105° C for ISC40SJ-TT) without changing the cell constant and conducting recalibration.

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 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 offline installation with double O-ring seals for long service life of the sensor.

The ISC40J have a large bore for optimal resistance to fouling processes and when properly installed, the flow will keep the sensor clean, to help avoid measuring errors.
Features
  • Inductive Conductivity technique for elimination of fouling and polarization errors.
  • Wide bore sensors for long term stability.
  • Installation flexibility due to wide range of holders and due to the use of universal bulkhead construction.
  • A single sensor can maintain the high resolution and accuracy, and measure the conductivity in an extremely brood range.
    • Minimum span: 100 μS/cm
    • Maximum span: 1,999 mS/cm
