FIGARO PRODUCT INFORMATION TGS 2610 - for the detection of LP Gas Features: Applications: * Low power consumption * High sensitivity to LP and its component gases (e.g. propane and butane) * Long life and low cost * Uses simple electrical circuit * Residential LP leak detectors and alarms * Portable LP detectors * LP gas and vapor detection 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 sensor resistance ratio (Rs/Ro) which is defined as follows: Rs = Sensor resistance in displayed gases at various concentrations Ro = Sensor resistance in 1800ppm of iso-butane TGS2610-C00 Sensitivity Characteristics: TGS2610-D00 Sensitivity Characteristics: 100 100 10 Air Ethanol 10 Rs/Ro Rs/Ro Air 1 Ethanol 1 Hydrogen Methane Iso-butane Propane Hydrogen Methane Iso-butane/Propane 0.1 100 0.1 1000 10000 Gas concentration (ppm) 100000 100 1000 10000 100000 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 FIGARO. 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 (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 alarm threshold value, keeping power dissipation (PS) of the semiconductor below a limit of 15mW. Power dissipation (PS) will be highest when the value of Rs is equal to RL on exposure to gas.

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 2612 has high sensitivity to methane, propane and butane, making it ideal for LNG and LPG monitoring. Due to its low sensitivity to alcohol vapors (a typical interference gas in the residential environment), the sensor is ideal for consumer market gas alarms. Due to miniaturization of the sensing chip, TGS 2612 requires a heater current of only 56mA and the device is housed in a standard TO-5 package. The figure below represents typical sensitivity characteristics, all data having been gathered at standard test conditions (see reverse side of this sheet).
