Paper Abstract

The perfonnance of a pressure transmission system containing a microbend fiber-optic pressure transducer is reported. The pressure transducer design is described along with the configuration for its installalion in a coal liquefaction reactor operating at a pressure of 3000 psi and temperatures up to 840°F. The modulated light intensity signal proportional to pressure is transmitted to the remote optoelectronic signal conditioner 250 feet from the reactor. The results of.a one-month field test include the calibration, measured pressure versus time, thennal and pressure cycling data, and failure mode.
