1. PREFACE
1.1 Introduction
This instruction manual provides
information for the installation and use of
the FU20, four-in-one wide body pH
sensors with a digital option for the
newest SENCOM platform. The FU20 is
the choice for most of the process
applications.
The Model FU20 offers a simple and cost-
effective solution for a wide variety of
process applications. This all-in-one
sensor provides simultaneous
measurement of pH, redox (ORP) and
temperature if desired. Chemical
compatibility in the target application is
secured by the choice of body material.
The rugged PPS body is designed for
easy installation into on-line and
threaded connections provided on both
ends of the sensor.
In applications where the sensor is
exposed to some concentrated acid or in
high temperature acid environment, the
material of choice will be PVDF. Optional
quick-removal adapters in both stainless
steel and titanium are available to make
calibration and maintenance even easier.
This four-in-one sensor provides
simultaneous measurement of pH, redox
(ORP) and temperature if desired. The
rugged body is designed for easy
installation via the 3/4hreaded
connections provided on both ends of the
sensor.
Additionally, the models type VP and VS
can be mounted in all angles including
Upside Down.
The FU20 sensor is available in two types:
3, 5,10 and 20 meters.
nector:
(VP- and VS- model)
The VP and VS model can be used with
an analogue analyzer in combination with
universal WU10- cable or halogen free
WE10- cable. Both cables are available in
different lengths.
The VS model with integrated ID-chip can
be used with SA11-P1 Smart Adapter,
which is placed directly on top of this
connector, or remotely connected using
the 3 meter WE10-H-D-003-V1 cable.
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 of FM-US and FM-
Canada, a separate label is delivered.
This label needs to be connected, in case
of use in United States and Canada in a
hazardous area, onto the sensor cable.
