FIBER OPTIC DEVICE FOR MONITORING THE ELECTRIC CURRENT TEMPERATURE AND PRESSURE

摘要

The invention relates to measuring equipment, namely to optical fiber devices and can be used in the oil industry, high-current electronics, power and for measuring the electric current control, pressure and temperature. The problem on which the utility model is directed, is to increase the measurement accuracy and the reliability of the control electric current control, pressure and temperature of production plants. The problem is solved in that the fiber-optical device electric current control, temperature and pressure contains three parallel fiber optical chain, the first as a photodetector optical radiation from the analyzer output used a photodiode connected to an amplifier and an ADC, the second optical fiber chain signal sensing element - controlling temperature T, in the form of an electrical signal reaches the amplifier and is also supplied to the ADC. The third fiber optic chain works as well as the second sensor element only via - controlling the pressure P, the amplifier and the ADC. The outputs from the ADC three fiber optic strings are connected to a computer which is connected electrically with the LCD, the output device for printing the data input device and a computer as a control keyboard, computer output is connected with an adjustable power source by a control signal transmission device.
