1. GENERAL
1-1. Introduction
This instruction manual provides
information for the installation and use
of the FU20, four-in-one wide body pH
sensors. The FU20 is the choice for the
majority of typical waste water and process
applications.
The Model FU20 offers a simple and cost
effective solution for a wide variety of
waste water and process applications. This
all-in-one sensor provides simultaneous
measurement of pH, redox (ORP) and
temperature if desired. The rugged Ryton
body is designed for easy installation into
on-line and immersion applications via the
3/4” NPT threaded connections provided
on both ends of the sensor. Optional
quick-removal adapters in both stainless
steel and titanium are available to make
calibration and maintenance even easier.
The FU20 comes with an integral cable of
optional lengths designed to minimize the
adverse affects noise can have on the
measurement. This cable is pre-finished
to make connection to any industrial pH
instrument as simple as possible.
The FU20 can also include a multipole
VP connector and then requires seperate
cable type WU10-V-S that is available
in 5 fixed lengths.
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 (including outer box) and then
immediately notify the carrier and the
relevant Yokogawa sales office. Make
sure the Model Code on the sensor is
the same as on the packing list. Also,
check any option(s) that were ordered are
included and correct. The sensor has an
identification number on the cable with
the full Model Code and a Serial Number
included.
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

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

4. Description of the fault and
circumstances of the failure.
5. Process/environmental conditions that
may be related to the failure of the sensor
6. Statement as to whether warranty or
non-warranty service is requested.
7. 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.
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 sensors/fittings have
been exposed.
