Description

Figaro’s TGS5342 is a battery operable electrochemical sensor which offers several advantages over traditional electrochemical sensors. Its electrolyte is environmentally friendly, it poses no risk of electrolyte leakage, can detect concentrations as high as 1% CO, operates in a range from -5 and +55℃, and it has lower sensitivity to interferant gases. With a long life, good long term stability, and high accuracy, this sensor is the ideal choice for CO detectors with digital display. OEM customers will find individual sensors data printed on each sensor in bar code from, enabling users to skip the costly gas calibration process and allowing for individual sensor tracking. The length of TGS5342 is 60% of the TGS5042.

The figure below represents typical sensitivity characteristics, all data having been gathered at standard test conditions (see reverse side of this sheet). The Y-axis shows theoutput current of the sensor (Iout/µA) in each gas. Output current is linear to CO concentration, with a deviation of less than ±5% in the range of 0~500ppm.  

Sensitivity Characteristics:

The figure below represents typical temperature dependency characteristics. The Y-axis shows the sensor output ratio (I/Io) as defined below. The linear relationship between I/Io and CO concentration is constant regardless of the CO concentration range.I = Sensor output current in 400ppm of CO at various temperaturesIo = Sensor output current in 400ppm at 20℃/50%RH
