| Abstract: | The overpressure protection equipment is mainly designed for hydraulic fracturing in oil field. It is a high intelligent monitoring and controlling equipment. Its adopts the high precision data conversion chip(A/D ICL7135),the correlated interface technology,RS 422 serial communication,the photoelectric isolation,the phonic compound method and so on. When the pressure exceeds the given range,the system works in the protection state and make the phonic prompt. It can either run along or on line work with the upper computer. The application effect shows that its measuring precision and reliablity can completely meet the actual demands and the good economic benefit has been got. |
