Abstract
This paper describes the development of a fibre optic pressure transducer based on the combination of an optical displacement sensor with a conventional pressure sensing mechanism. The fibre optic displacement sensor utilised was of the wavelength modulation type and had previously been demonstrated to have a resolution of 6.5um over a range of 10mm when illuminated by a white light sourcel. In the work described here the source was replaced by a near-infra-red light emitting diode whose spectral bandwidth provided a displacement range of lmm. This sensor was fitted to a conventional pressure sensing mechanism which produced a displacement of lmm in response to an applied pressure of 30mbar. This paper reports on the evaluation of the transducer and gives the results of the performance in terms of hysteresis and linearity.
