1. PREFACE

1.1 Introduction

These high temperature conductivity
sensors have a stainless-steel body and a
ceramic insulation, especially designed to
withstand high temperatures (up to
250°C) and pressures (up to 40 bar).
A special treatment of the electrodes
ensures optimal resistance against
polarization.
The flanged model has an integral
connection box, the threaded models are
provided with a Amphenol connector to fit
the Yokogawa WU40 cable, or with a
Variopin connector to fit with Yokogawa
WU10/WE10-cable.
The sensor and associated fitting program
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 Instruction
Manual.
All sensors have a pre-calibrated cell
constant and a built-in temperature
element for automatic temperature
compensation. Sensors with the Variopin
connector are equipped with an ID-chip in
which calibration information is stored for
easy setup when connected to a
SENCOM Smart Adapter model SA11-C1.
For metal sensors a 3.1 material
certificate is included. The sensor is
certified for hazardous area when
connected to a certified intrinsically safe
Yokogawa analyzer, model SC202S or
FLXA-series or SA11-C1 or to a certified
intrinsically safe circuit with defined output
parameters.

1.2 Unpacking and Checking

Upon delivery, unpack the sensor
carefully and inspect it to ensure it was
not damaged during shipment. If damage
is found, retain the original packing
materials and then immediately notify the
carrier and the relevant Yokogawa sales
office.
Make sure the Model Code and Serial
Number on the sensor are the same as on
the packing list. Also, check any option(s)
that were ordered are included and
correct.
For some specific sensor information, the
size of the sensor label is not big enough.
For that reason and specifically for
information related to the intrinsically
safety compliance like ATEX, IECEx, FM-
United States and FM-Canada, a
separate label is delivered. This label
needs to be connected onto the sensor
cable close to the sensor.

1.3 Warranty and Service

Yokogawa products and parts are
guaranteed free from defects in
workmanship and material 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 are excluded from this warranty
coverage. In the event of warranty claim,
the defective goods should be sent
(freight paid) to the Service Department of
the relevant sales Organization for repair
or replacement (at Yokogawa's
discretion).
