Abstract
The utility model belongs to the technical field of analysis instrument equipment, and particularly relates to a double-passage oxygen analysis instrument used for monitoring and analyzing oxygen content in mixed gas in real time. The double-passage oxygen analysis instrument comprises an oxygen content sensor, a signal amplification circuit, a data collecting circuit and a display operation unit in sequential connection and is characterized by comprising a group of parallel oxygen content sensors and a signal amplification circuit. The double-passage oxygen analysis instrument can be used for monitoring and analyzing the oxygen content in the mixed gas in real time. The oxygen content sensor in the instrument adopts an electric chemical principle, the output voltage is in linear change along with the oxygen content, the precision of the data collecting circuit is high, the operation is reliable, and the instrument can realize the data display and calibration, sensor failure warning and the like. The double-passage oxygen measurement aims at some multi-point oxygen measurement conditions, and the number of used instruments can be reduced, so the cost is saved.
Description
Technical field
The utility model belongs to the analysis Instrument equipment technical field, is specifically related to the analyser of oxygen content in a kind of real-time monitoring analysis mixed gas.
Background technology
The instrument that is used for the real-time monitoring analysis of oxygen in the market; Generally be the single channel analyser, need the situation of multiple spot oxygen measurement, then will use many instruments for some; Cost is higher, and the hyperchannel oxygen analyser can reduce instrument and install, reduces use cost.
Mostly product is the single channel analyser with the manufacturing of principles such as fuel cell lambda sensor, electrolytic cell lambda sensor, zirconia sensor, the analysis of magnetic oxygen, laser.The fuel tank lambda sensor is to be made up of highly active oxygen electrode and lead electrode, is immersed in alkalescence or the acid solution, and redox reaction takes place, according to the oxygen concentration measurement oxygen content that is directly proportional with voltage.The core component of zirconia sensor is a zirconia solid electrolyte, ZrO
2Solid electrolyte is made up of multivariant oxide, the O that passes through under the high temperature
2The quantity of concentration affects electron transfer, sensor electrical kinetic potential and O
2Concentration has functional relation, and then calculates O
2Concentration.The magnetic susceptibility that magnetic oxygen analyser is based on oxygen is measured the physics formula gas analyzer of oxygen content in the combination gas much larger than the physical phenomenon of other gas magnetic susceptibility, can be divided into the magnetic machinery formula, magnetic pressure type, Thermomagnetic type etc.
Summary of the invention
The objective of the invention is the deficiency that exists in use to prior art, for saving cost aspect the hyperchannel oxygen measuring, and a kind of galvanochemistry binary channels oxygen analyzer that proposes.
The main technical schemes of the utility model: the binary channels oxygen analyzer, comprise the oxygen quantity sensor, signal amplification circuit, data acquisition circuit and the display operation unit that connect successively, it is characterized in that comprising one group of oxygen quantity sensor and signal amplification circuit arranged side by side.
Usually, the described oxygen quantity sensor of the utility model, signal amplification circuit, data acquisition circuit and display operation unit all can be realized through the assembly that this field is known.
The utility model binary channels oxygen analyzer is oxygen content in the monitoring analysis mixed gas in real time.The oxygen quantity sensor of instrument adopts electrochemical principle, and output voltage is linear change with oxygen content; The data acquisition circuit precision is high, reliable; Instrument can realize data presentation, demarcation, sensor failure warning etc.The binary channels oxygen measurement is directed against the situation of some multiple spot oxygen measurements, the quantity of instrument capable of reducing using, thus save cost.
Description of drawings
Accompanying drawing 1 is the syndeton synoptic diagram of the utility model embodiment analyser.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Embodiment: the syndeton of present embodiment binary channels oxygen analyzer is shown in accompanying drawing 1; Mainly comprise successively the oxygen quantity sensor, signal amplification circuit, data acquisition circuit and the operation display interface that connect, it mainly improves is to comprise one group of oxygen quantity sensor 1 arranged side by side and 2 and signal amplification circuit 1 and 2.
In the present embodiment, gas is through getting into analyser after the pre-service, and the signal of two lambda sensors 1 and 2 detections all through separately amplifying circuit 1 and 2, gets into Acquisition Circuit then, in single-chip microcomputer, accomplishes data processing, at last video data on liquid crystal display.The user also can according to operation indicating, check the battery original signal on user interface, and carries out conventional proving operation.
The present embodiment signal amplification circuit separates with data processing circuit, and magnification circuit plate can carry out the circuit adjustment according to sensor model number, has increased the extensibility of system; Data-interface is simple, is convenient to be connected with other devices communicatings; Double channel data acquisition when some multi-point data acquisitions, can reduce cost, and instrument program is simplified, and is simple to operate.
