PRODUCT INFORMATION Features: * Linear output * Long life * Small sensitivity to alcohol * Sensitive to both methane and LP gas Applications: * Residential LNG and LPG alarms * Detectors for LNG and LPG The TGS6810-D00 catalytic type gas sensor, which can detect both methane and LP gas, has been developed for residential gas detection. Combining Figaro's extensive experience in catalyst materials technology with its advanced micro fabrication technology, Figaro can produce the most advanced compact catalytic sensors whose durability, stability, quick response, and linear output make them ideal for detecting many combustible gases. As the sensor possesses an adsorbent inside its sensor cap, its cross sensitivity to alcohol is small. In addition, TGS6810-D00 is durable against silicone compounds. The figure below represents typical sensitivity characteristics, The figure below represents typical temperature dependency all data having been gathered at standard test conditions (see characteristics at 65%RH. Again, the Y-axis is indicated as reverse side of this sheet). The Y-axis is indicated as sensor sensor output sensitivity--AVout (mV): output sensitivity--AVout (mV): AVout = Vout in gas - Vout in air at 20°C AVout = Vout in gas - Vout in air Gas concentration (ppm) Ambient temperature ( C) 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 TGS6810 is comprised of two elements: 1) element (D) which is sensitive to combustible gases and 2) a reference element (C) which is not sensitive to combustible gases. These elements are installed into a “Wheastone Bridge”. Avariable resistor should be adjusted so that the bridge will produce a stable baseline signal when in an environmnet free of combustible gases. When combustible gases are present, they will be combusted on the detecting element, causing its temperature to rise. Accordingly the resistance of this element will increase. This results in an “out-of-balance”...
