IMPORTANT NOTE: OPERATING CONDITIONS IN WHICH FIGARO SENSORS ARE USED WILL VARY WITH EACH CUSTOMER’S SPECIFIC APPLICATIONS. FIGARO STRONGLY

RECOMMENDS CONSULTING OUR TECHNICAL STAFF BEFORE DEPLOYING FIGARO SENSORS IN YOUR APPLICATION AND, IN PARTICULAR, WHEN CUSTOMER’S TARGET

GASES ARE NOT LISTED HEREIN. FIGARO CANNOT ASSUME ANY RESPONSIBILITY FOR ANY USE OF ITS SENSORS IN A PRODUCT OR APPLICATION FOR WHICH SENSOR HAS

NOT BEEN SPECIFICALLY TESTED BY FIGARO.

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

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.
