Paper Abstract

A new sensor has been developed for high hydrostatic pressure measurement based on displacement of the absorption edge in a semiconductor under the effect of pressure. The sensing element is composed of a GaAs single-crystal which has been attached to two multimode optical fibers. The crystal is placed inside a high-pressure chamber while fibers are used to carry the optical signal in and out. The present configuration allows determination of pressure up to 100 MPa. Temperature effects in the range 10°C to 50°C have also been investigated.
