PRODUCT INFORMATION TGS 2611-C00 - for the detection of Methane Features: * Quick response * Low power consumption * Long life and low cost * Uses simple electrical circuit * Portable gas detectors * Gas leak detector for gas appliances TGS2611-C00 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-C00 requires a heater current of only 56mA and the device is housed in a standard TO-5 package. TGS2611-C00 possesses small size and quick gas response, making it suitable for gas leakage checkers. The TGS2611-C00 is able to satisfy the requirements of performance standards such as UL1484 and EN50194. 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 at various concentrations Ro = Sensor resistance in 5000ppm of methane The figure below represents the typical response pattern when the sensor is inserted into and later removed from 5000ppm of methane. Sensitivity Characteristics: Ethanol Hydrogen Iso-butane Gas concentration (ppm) 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 FIGA

Basic Measuring Circuit: The sensor requires two voltage inputs: heater voltage (Vh) and circuit voltage (Vc). The heater voltage (Vh) is applied to the integrated heater in order to maintain the sensing element at a specific temperature which is optimal for sensing. Circuit voltage (Vc) is applied to allow measurement of voltage Vout(Vrl) across a load resistor (Rl) which is connected in series with the sensor. A common power supply circuit can be used for both Vc and Vh to fulfill the sensor's electrical requirements. The value of the load resistor (Rl) should be chosen to optimize the...
