Figaro Combustible gas Sensor for the detection of LP Gas
Model:TGS2610
TGS2610 is a semiconductor type gas sensor which combines very high sensitivity to LP gas with low power consumption and long life. Due to miniaturization of its sensing chip, TGS2610 requires a heater current of only 56mA and the device is housed in a standard TO-5 package.
The TGS2610 is available in two different models which have different external housings but identical sensitivity to LP gas. Both models are able to satisfy the requirements of performance standards such as UL1484 and EN50194.
TGS2610-C00 possesses small size and quick gas response, making it suitable for gas leakage checkers. TGS2610-D00 uses filter material in its housing which eliminates the influence of interference gases such as alcohol, resulting in highly selective response to LP gas. This feature makes the sensor ideal for residential gas leakage detectors which require durability and resistance against interference gas.
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 sensorresistance ratio (Rs/Ro) which is defined as follows:
Rs = Sensor resistance in displayed gases at various concentrations
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/humiditiesRo = Sensor resistance in fresh air at 20°C and 65% R.H.
