FIGARO PRODUCT INFORMATION TGS 2611 - for the detection of Methane 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 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 2611 has high sensitivity and selectivity to methane gas. Due to its low [ ... ]
