I. Overview This instrument is the use of oxygen measuring principle, by the oxygen sensor in the oxygen concentration in the gas is converted into an electrical signal by subtraction to calculate the nitrogen content in order to pour the calculated and measured gas directly display the percentage nitrogen content. The instrument uses advanced LSI and five and a half high brightness LED digital display, with digital dial to set the lower limit control function, and convenient. When the nitrogen content of the system being monitored is below the set value, the control contact start, and a sound / light alarm simultaneously. The instruments also 4-20MA sync signal output, and automatic zeroing function, the instrument can display directly hundred thousandth reading (99.999%), fast response, high precision, stable and reliable, simple operation. The content of this instrument can be used nitrogen 79.0% air calibration, easy to operate and has automatic range switching circuit, when the nitrogen concentration greater than 90.3%, then the instrument automatic conversion range, the reading is 90.300%. When the nitrogen concentration is below the lower limit of the 1st set value (if it is 99.96%), alarm indicator light, while an alarm sounds, the 1st alarm output switch start (can be warnings, or start the corresponding device) .. when nitrogen concentration continues to fall below the lower limit set value 2 (if it is 99.93%), the 2nd alarm output switch activation. (can be noted in the appropriate control equipment need to start) .. so that is more conducive to product quality and production management. If with only one way to set the value, then to the 2nd lower control digital dial to 90.00 .2 kinds of instruments can come with 4 ~ 20mA signal output can be connected to the recorder. The instrument is suitable for PSA nitrogen machine, air separation equipment, and the nitrogen concentration in the nitrogen-oxygen gas mixture analysis, monitoring and control.

Introduction When the nitrogen concentration is less than the lower limit value 1 (if it is 99.96%), alarm indicator light, while an alarm sounds, the 1st alarm output switch start (can be warnings, or start the corresponding device). When the nitrogen concentration continues to fall below the lower limit of the 2nd set value (if it is 99.93%), the 2nd alarm output switch activation. (can be noted in the appropriate control equipment need to start) .. so that is more conducive to product quality production management. If only 1 channel setting, then put on the 2nd lower control digital dial to 90.00 .2 kinds of instruments can come with 4 ~ 20mA signal output can be connected to the recorder.
