ter 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 performance and functions due to incorporation

of electrostatic capacitance type silicon sensor and micro-

processor.

forms an optical field instrumentation system together with

an optical star coupler and a master station.

FEATURES

1. Resistive to noise and lightning

2. Reliability due to redundant configuration

3. Intrinsic safety type explosion-proof

A fiber optic cable used for the signal transmission line

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.

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.

Each equipment with a built-in battery can be constructed

so as to be an intrinsic safety type individually (intrinsic

safety type barrier unnecessary).
