1. PREFACE
1.1 Introduction
This instruction manual provides information
for the installation and use of the FU20F
SENCOM™ sensor. This digital sensor
shows how Yokogawa applies the motto
“Simply the Best” to sensor technology.
Setup of the sensor is very easy because
all sensor specific characteristics, such as
calibration data, are stored in the sensor.
The FU20F SENCOM™ sensor holds
four separate measuring elements in one
unbreakable and chemical resistant
PPS 40GF (Ryton
TM ) wide body:
• pH glass electrode.
• Long life saturated Ag/AgCl reference
system with double junction, combined
with ion-trap to prolong the lifetime of
the reference probe even in chemically
unfavorable environments.
• Integral Pt1000 element for accurate
temperature measurements.
• Solid Platinum ORP/LE electrode for
accurate simultaneous pH and ORP
measurements.
Other valuable features of the sensor:
• PTFE reference diaphragm to prevent
fouling.
• Polymerized electrolyte to extend the
sensor lifetime.
• Available in two versions, a robust dome
shape model for applications with a
limited amount of solids, and a flat surface
model for applications in which solids are
a considerable component, such as in the
pulp and paper industry.
• Versatile in-line or off-line installation.
Optional quick-removal adapters in both
stainless steel and titanium are available
to make calibration and maintenance even
easier.
The FU20F is provided with a multipole
M9 male connector for connection to the
Yokogawa FLXA analyzer using the WU11
interconnection cable for SENCOM™
sensor. This cable, available in 4 fixed
lengths, is specified for reliable transfer of
digital signals and especially designed to be
installed in a heavy industrial environment.
The double shielded cable will protect both
the sensor and the analyzer for interference
from high voltages and currents which are
present on other cables.
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 non-
warranty service is requested.
