OPTICAL DIFFERENTIAL PRESSURE (FLOW) TRANSMITTER
DATA SHEET
FFK···3
The Model FFK 3 Optical Differential Pressure (Flow)
Transmitter measures differential pressures (flow rates) of
various fluids accurately, converts them into optical digital
signals and outputs them. This is an intelligent transmitter
providing excellent performance and functions due to in-
corporation of electrostatic capacitance type silicon sensor
and microprocessor.
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.
FEATURES
1. Resistive to noise and lightning
Optical signal ensures a reliable signal transmission, be-
cause it is not be affected by external noise and induc-
tive 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).
