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 car-
ries out digital processing of signals for ensuring a high ac-
curacy and an intelligent operation.
FUK
A fiber optical cable used for the signal transmission line
FUL
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 in-
ductive 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).
