Yokogawa Terminal Box BA20/YT
GENERAL
The
ISC40GJ, ISC40SJ sensors are designed for use with the 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 130oC, -10 to 105oC 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
Concen- trated 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 off-line installation with double
O-ring seals for long service life of the sensor.
The
ISC40GJ, ISC40SJ 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
Yokogawa Terminal Box BA20/YT
•
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.

APPLICATIONS
Yokogawa Terminal Box BA20/YT
•
All applications where severe electrode fouling prevents the use of contacting
electrodes.
•
All ranges except (ultra) pure water applications.
•
All slurry applications where conventional systems suffer from plugging or
erosion.

(Note) Do not submerge the sensor itself in process
water, as the seams between the mold and the metal of the sensor are not
waterproof. Since a temperature sensor is imbedded in the PEEK molded sensor,
its response speed is not fast. Install another temperature sensor if
necessary.
