OPTICAL PRESSURE TRANSMITTER
DATA SHEET
FBL···3
The Model FBL 3 Optical Pressure Transmitter measures
pressures of various fluids accurately, converts them into
optical digital signals and outputs them. This is an intelli-
gent transmitter providing excellent performance and func-
tions due to incorporation 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 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 re-
alized.
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
