Abstract
The article discusses the issues of creating a fiberoptic pressure sensor for remote monitoring of the parameters of pneumatic and hydraulic highways intended for the transportation of fire and explosive media (flammable gases, liquids), or pneumatic-hydraulic systems operated in fire and explosive conditions. The proposed solution does not require explosion-proof design and uses elastic sensitive elements and polarimetric optical modulator, which are the simplest in terms of the production process. The principle of operation of a fiber-optic pressure sensor is described, a block diagram of its primary and secondary converters is given, a three-dimensional model of the sensor is devel-oped, according to which an experimental sample of the sensor is made and a stand for its study is developed. For the experimental sample, the working section of the conversion function is 3.5 ...6.5 bar, the average sensitivity value is 0.061 mW/bar (4.97 dBm/bar), the spread of the recorded optical power between the conversion curves in the working section does not exceed 2.62%. To ensure higher metrological characteristics of the sensor, corresponding design recommendations are given.
