Abstract

The invention relates to a zirconium oxide oxygen content analysis instrument with a paperless recording instrument. The zirconium oxide oxygen content analysis instrument is characterized by comprising a microprocessor, wherein the microprocessor is connected with display equipment, a gas path unit and storage equipment. The instrument adopts a color liquid crystal display as the display equipment to display the measured real-time oxygen content in the form of characters. The display has a touch function, an operator can touch a press key of the display to switch into a recording state, the instrument displays the history record of oxygen content measurement in the form of a curve, the sampling interval is one second, the recording length is about 5.8 days, and a user can quickly browse the history record by operating a touch screen. The recorded data can be exported by an upper computer through a computer interface.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a zirconia oxygen analyzer with a paperless recorder. Background technique [0002] Zirconia oxygen analyzer (hereinafter referred to as instrument) is widely used in the combustion efficiency control of boilers, kilns and other equipment. Due to the requirements of on-site measurement, the instrument is usually on-line for a long time. The instrument converts the measured oxygen content into a standard current signal and provides it to DCS for on-site control. However, on-site operators generally can only observe real-time data, and cannot check the continuous measurement status of the instrument. If the paperless recorder is connected, it needs to increase investment, and the setting of the recorder is also relatively complicated. Contents of the invention [0003] The purpose of the present invention is to provide an improved zirconia oxygen analyzer with a pa...
