PRODUCT INFORMATION TGS 5141-P00 - for the detection of Carbon Monoxide * Ultra compact * Battery operable * High repeatability/selectivity to CO * Linear relationship between CO gas concentration and sensor output * Simple calibration * Long life * UL recognized component * Meets UL2034, EN50291, and EN54-31 requirements * Residential and commercial CO detectors * Fire detection Figaro’s TGS5141 is a battery operable electrochemical sensor which uses a unique electrolyte that eliminates the need for a water reservoir. By eliminating the water reservoir used in TGS5042, the comparative size of TGS5141 is reduced to just 10% of TGS5042. With its ultra compact size, this sensor is the ideal choice for size oriented applications such as portable CO detectors, small residential CO detectors, and multi-sensor fire detectors. OEM customers will find individual sensors data printed on each sensor in bar code form, enabling users to skip the costly gas calibration process and allowing for individual sensor tracking. 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 shows theoutput current of the sensor (Iout/µA) in each gas. Output current is linear to CO concentration, with a deviation of less than ±5% in the range of 0~1000ppm. The figure below represents typical temperature dependency characteristics. The Y-axis shows the sensor output ratio (I/Io) as defined below. The linear relationship between I/Io and CO concentration is constant regardless of the CO concentration range. I = Sensor output current in 400ppm of CO at various temperatures Io = Sensor output current in 400ppm at 20˚C/50%RH Sensitivity Characteristics: 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

Basic Measuring Circuit: The diagram at the right shows the basic measuring circuit of TGS5141. The sensor generates a minute electric current which is converted into sensor output voltage (Vout) by an op-amp/resistor (R1) combination. Figaro recommends the following electrical parts: R1 : 1MΩ C1 : 1µF IC : AD708 NOTE: When voltage is applied to the sensor output terminal, the sensor may be damaged. Voltage applied to the sensor should be strictly limited to less than ±10mV. An additional resistor or FET is required to prevent polarization of the sensor when Vc is off. Basic measuring...
