TGS 5342 - for the detection of Carbon Monoxide
The gure 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.
The gure below represents typical temperature dependency
characteristics. The Y-axis shows the sensor output ratio (I/Io)
as dened 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
temperatures
Io = Sensor output current in 400ppm at 20˚C/50%RH
* Residential and commercial CO detectors
* CO monitors for industrial applications
* Ventilation control for indoor parking garages
* Recreational vehicle CO detectors
* Marine CO detectors
* Fire detection
Figaro’s TGS5342 is a battery operable electrochemical sensor which offer 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 -40˚ and +70˚C, 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
nd 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.
* Battery operable
* Compact size
* High repeatability/selectivity to CO
* Linear relationship between CO gas
concentration and sensor output
* Simple calibration
* Long life
* UL recognized component
* Meets UL2034, EN50291, and RoHS
requirements
