1. PREFACE
1.1 Introduction
Model SC41, SC42 and SC49 sensor,
available in various materials such as
Epoxy, Stainless Steel, PTFE and PVDF,
is intended to suit most process
conditions. The sensor is provided either
with an Amphenol connector to fit the
Yokogawa WU40 cable or Variopin
connector to fit with Yokogawa
WU10/WE10-cable. A wide range of flow
and immersion fittings makes it possible to
install the sensor in a permanent or semi-
permanent location. The fittings of
stainless steel might be used in sanitary
applications. 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 SC42
model 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).
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
non-warranty 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.
