%X A pressure sensor system is presented based on fiber loop which consists of two couplers and a single mode fiber and the measured pressure was converted into the ringdown time of light traveling in the fiber loop by the sensor element of FBG. When the pressure was changed, the pressure was directly proportional to the ringdown time which is the same with the theory. This kind of system of measuring press based on the theory has the advantages of simple composition and convenient measure and it provides a novel method of fiber gratting demodulation technology and has practical value.Apart from measuring press ,it can measure temperature and other parameters.
