PRODUCT INFORMATION Features: * High selectivity to LP and its component gases (e.g. propane and butane) * Low power consumption * Long life and low cost * Uses simple electrical circuit Applications: * Residential LP gas detectors and alarms * Portable LP gas detectors * LP gas and vapor detection TGS2610-D00 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-D00 requires a heater current of only 56mA and the device is housed in a standard TO-5 package. 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 TGS2610-D00 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 1800ppm of iso-butane The figure below represents typical temperature and humidity dependency characteristics. The Y-axis is indicated as sensor resistence ratio (Rs/Ro), defined as follows: Rs = Sensor resistance in 1800ppm of iso-butane at various temp/humidities Ro = Sensor resistance in 1800ppm of iso-butane at Temperature and Humidity Dependency: 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 (Vout) 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...
