DEVICE FOR MONITORING OIL CONCENTRATION IN COMPRESSED GAS OF COMPRESSOR STATION Russian patent published in 2024 - IPC G01N21/64 G01N33/26 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a device for determining the concentration of oil in the compressed gas of a compressor station and can be used to monitor its operation and prevent a possible emergency explosive situation when the maximum permissible concentration of an impurity in the form of oil vapour is reached when using mineral or synthetic oils. The device for monitoring the concentration of oil in the compressed gas of a compressor station includes a high-pressure chamber in the form of a flow cell for the analysed gas, equipped with sight glasses and a flow limiter installed at the output, a pulsed source of ultraviolet radiation, an optical system for generating excitation radiation of the analysed gas, and a first photodetector device intensity of exciting radiation, a second photodetector for recording excited radiation passing through the viewing glass of the cuvette, a third photodetector for recording radiation passing through two viewing glasses of the cuvette, as well as the first and second indicator devices and a comparator, output of which is connected to the first indicator device. Additionally, an amplifier with an adjustable gain, an amplifier with a controlled gain, a signal conditioner for device health, a differential amplifier and a trigger pulse shaper connected in series with a pulsed source of ultraviolet radiation are introduced. In this case, the input of the amplifier with an adjustable gain is connected to the output of the first photodetector, the first input of the device health signal generator and the first input of the differential amplifier, the second input of which is connected to the output of the third photodetector device, and the output is connected to the second indicator device, the second input of the health signal generator devices and the first input of an amplifier with a controlled gain, the second input of which is connected to the output of the second photodetector and the third input of the device health signal generator, the output of which is connected to the first input of the control computer complex of the compressor station. In addition, the output of the amplifier with a controlled gain is connected to the first input of the comparator, the second input of which is connected to the output of the amplifier with a controlled gain, and the output of the comparator is connected to the second input of the control computer complex of the compressor station.

EFFECT: expanding the functionality of the device while ensuring high efficiency of its operation.
