Product Specification

Features:

* Low power consumption
* High sensitivity to methane
* Long life and low cost
* Uses simple electrical circuit

Applications:

* Domestic gas alarms
* Portable gas detectors
* Gas leak detector for gas appliances

TGS2611 is a semiconductor type gas sensor which combines very high sensitivity to methane gas with low power consumption and long life. Due to miniaturization of its sensing chip, TGS2611 requires a heater current of only 56mA and the device is housed in a standard TO-5 package.
The TGS2611 is available in two different models which have different external housings but identical sensitivity to methane gas. Both models are able to satisfy the requirements of performance standards such as UL1484 and EN50194.
TGS2611-C00 possesses small size and quick gas response, making it suitable for gas leakage checkers.
TGS2611-E00 uses filter material in its housing which eliminates the influence of interference gases such as alcohol, resulting in highly selective response to methane 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 sensor resistance ratio (Rs/Ro) which is defined as follows:
Rs = Sensor resistance in displayed gases at various concentrations
Ro = Sensor resistance in 5000ppm of methane
