FFI SYSTEM
OPTICAL TEMPERATURE TRANSMITTER
DATA SHEET
FUK···3, FUL···3, FUM···1
The Model FUK 3/FUL 3/FUM 1 is Optical Temperature
Transmitter for thermocouple or platinum resistance bulb
used for measuring the temperature of different fluids. The
transmission unit incorporates a microprocessor that carries out digital processing of signals for ensuring a high accuracy and an intelligent operation.
A fiber optical cable used for the signal transmission line
forms an optical field instrumentation system together with
an optical star coupler and a master station.

MODEL TYPE CONFIGURATION
1) Thermocouple temperature transmitter (integrated type),
Model type: FUK
2) Resistance bulb temperature transmitter (integrated type),
Model type: FUL
3) Temperature transmitter (separate type), Model type:
FUM
FUM
FEATURES
1. Resistive to noise and lightning
Optical signal ensures a reliable signal transmission,
because it is not be affected by external noise and inductive lightning. Use of a nonmetallic optical (fiber) cable
prevents propagation of inductive lightning through the
cable, so a signal transmission immune to lightning can
be realized.
2. Reliability due to redundant configuration
Host system can be duplicated by using two optical cable
trunk lines (between an optical star coupler and host
system). This enhances reliability of users' systems.
3. Intrinsic safety type explosion-proof
Each equipment with a built-in battery can be constructed
so as to be an intrinsic safety type individually (intrinsic
safety type barrier unnecessary).

Description
Note: For operation of the "3" type transmitter ("3" at the 8th digit of
product code), a hand-held communicator is required to have
a version 1.6 or higher, but a communicator before version
1.6 can be operated with memory data updated.
(Refer to the instruction manual of temperature transmitter.)

SCOPE OF DELIVERY
Instrument body and pipe fixture (for separate type)
Relation between velocity of fluid measured
and insertion length
When measuring a temperature upon insertion in the fluid
piping, the temperature detector is subjected to a stress
by fluid flow. So, the mechanical strength of a protective
pipe to put in must be taken into account.
Study the insertion length for a thermometer to use referring to the relation between velocity and insertion length in
Fig. 1.
If a sheath type is inserted in fluid, provide a protective
pipe separately.
