Abstract
Optical pressure transducers are used in devices for the measurement of the pressure of explosive gasses and liquids. In order to increase the sensitivity of the optical pressure transducer, the diaphragm (3) is made to be reflective on both sides. Two pairs of light conductors, each comprising a first light conductor (10, 11) for a light emission and a second light conductor (12, 13) for intercepting the light reflected by the diaphragm (3), are arranged on opposite sides of the diaphragm.
