1 INTRODUCTION

1.1 General

The sensor and fitting program for inductive
conductivity measurement (model ISC40)
is designed to meet the most common
installation requirements in terms of material
compatibility, process connections and
flow dynamics. The various installation
possibilities are described and illustrated in
this manual.
The following categories of installation can
be recognised:

1. Direct mounting of sensors in tank wall or
customer supplied flanges

2. Cost effective installation of sensors
using process adapters

3. Maintenance friendly installation of
sensors using in-line subassemblies

4. Installation in flow chambers for
measurements in sample streams or
bypass loops

5. Installation in immersion fittings for
measurement in open tanks or channels

Within the wide range of process adapters,
subassemblies, flow fittings and immersion
fittings it is easy to find the appropriate
installation that fits the application (a wide
choice of materials), the plant installation
practice (a wide choice of process con­nections) and the maintenance procedures.

1.2 Unpacking and Checking

Upon delivery, unpack the sensor carefully
and inspect it to ensure that it is not
damaged during shipment. If damage is
found, retain the original packing material
and immediately notify the carrier and the
relevant local Yokogawa Sales office.
Make sure the Model Code and Serial
Number on the sensor are the same as on
the packing list. Also check if option(s) that
were ordered, are included and correct.

1.3 Warranty and Service

Yokogawa products are guaranteed free
from defects in workmanship and materials
under normal use and service for a period
of (typically) 12 months from the date of
shipment from the manufacturer. Individual
Sales organizations can deviate from the
typical warranty period, and the conditions
of sale relating to the original purchase
order should be consulted. Damage caused
by wear and tear, inadequate maintenance,
corrosion, or by the effects of chemical
processes is excluded from this warranty
coverage. In the event of a warranty claim,
the defective goods should be sent (freight
paid) to the Service Department of the
relevant Yokogawa Sales office for repair or
replacement (at Yokogawa’s discretion).

The following information must be included
in the letter accompanying the returned
goods:

• Model Code and Serial Number.

• Original Purchase Order and Date.

• Length of time in service and description
of the process.

• Description of the fault and circumstances
of the failure.

• Process/environmental conditions that
may be related to the failure of the sensor.

• Statement as to whether warranty or non­warranty service is requested.

• Complete shipping and billing instructions
for return of material, plus the name and
phone number of a contact person that
can be reached for further information.

• Clean Statement
Returned goods that have been in
contact with process fluids must be
decontaminated and disinfected prior
to shipment. Goods should carry a
certificate to this effect, for the health and
safety of our employees. Material Safety
Data sheets must be included for all
components of the process to which the
sensor(options) have been exposed.

2 GENERAL SPECIFICATIONS

The ISC40 inductive conductivity sensor is suitable for use with the Yokogawa inductive
conductivity analyzers.

2.1 Measuring elements

: Toroïds with high permeability magnetic material

Pt1000 or 30k temperature element

2.2 Materials
Wetted parts sensor

Body ISC40*-G* : 30% glass filled PEEK, FDA approved
Body ISC40*-T* : PFA, FDA approved, PIM regulation 10/2011 approved
Non-wetted parts sensor
Sealing gasket : Viton
Thread part : AISI 316 SS
Options for sensor
All options except /TFD : AISI 316 SS and O-ring material as wetted part
/TFD : AISI 316 SS as non-wetted part

TFM and Kalrez as wetted part

2.3 Functional specifications (at 25°C)

Temperature element : Pt1000 to IEC 751

30k NTC

Installation factor : 1.88 cm-1 nominal for PEEK sensor

3.00 cm-1 nominal for PFA sensor
Actual installation can change this factor.
If there is less than 25mm spacing between sensor and holder,
in-situ calibration is necessary to meet the specified accuracies
(see fig. 1)

Fig 1: Actual installation factor as function of spacing around the sensor

Note: The ISC40 temperature sensor is designed for cell compensation and for indication.

It is NOT designed for process temperature control.
