Features: Applications:
TGS 2600 - for the detection of Air Contaminants
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 is indicated as sensor
resistance ratio (Rs/Ro) which is defined as follows:
Rs = Sensor resistance in displayed gases at
various concentrations
Ro = Sensor resistance in fresh air
The figure below represents typical temperature and humidity
dependency characteristics. Again, the Y-axis is indicated as
sensor resistance ratio (Rs/Ro), defined as follows:
Rs = Sensor resistance in fresh air
at various temperatures/humidities
Ro = Sensor resistance in fresh air
at 20°C and 65% R.H.
* Air cleaners
* Ventilation control
* Air quality monitors
The sensing element is comprised of a metal oxide semiconductor layer formed
on an alumina substrate of a sensing chip together with an integrated heater.
In the presence of a detectable gas, the sensor's conductivity increases
depending on the gas concentration in the air. A simple electrical circuit can
convert the change in conductivity to an output signal which corresponds to the
gas concentration.
The TGS 2600 has high sensitivity to low concentrations of gaseous air
contaminants such as hydrogen and carbon monoxide which exist in cigarette
smoke. The sensor can detect hydrogen at a level of several ppm. Figaro also
offers a microprocessor (FIC02667) which contains special software for handling
the sensor's signal for appliance control applications.
Due to miniaturization of the sensing chip, TGS 2600 requires a heater current
of only 42mA and the device is housed in a standard TO-5
