Microprocessor-Controlled Fibre-Optical Pressure Sensor

Microprocessor-controlled fibre-optical pressure sensor is presented. Special care has_ been laid down to safety in heavy-duty conditions and to simplicity of operation. All-optical gauge for measuring pressure in a range of 0 - 1000 hPa is based on a fibre-optical displacement sensor with a membrane being deformed by the acting pressure. The applied numerical data processing makes the measurement result quick and easy. The sensor is recommended to operate in a combustible and corrosive atmosphere.
