FFI SYSTEM
OPTICAL PRESSURE TRANSMITTER REMOTE SEAL TYPE
DATA SHEET
'#.ʜ
The Model FBM 3 Optical Pressure Transmitter Remote
Seal Type measures pressures of various fluids accurately,
converts them into optical digital signals and outputs them.
This is an intelligent transmitter providing excellent perfor-
mance and functions due to incorporation of electrostatic
capacitance type silicon sensor and microprocessor.
A fiber optic 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 affected by external noise and inductive
lightning. Use of a nonmetallic optical (fiber) cable pre-
vents propagation of inductive lightning through the cable,
so a signal transmission immune to lightning can be real-
ized.
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 sys-
tem). 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).
