PRODUCT CATALOGUE 2 an ISO9001 company FIGARO GAS SENSORS 2000 Series The FIGARO 2000 Series comprises a new type of thick film metal oxide semiconductor gas sensor fabricated using a novel screen printing technique. This Technique enables narrow sensor to sensor variation within production lots. Additionally, Figaro's material technology has expanded the range of sensing materials to metal oxides other than the tin dioxide. Gases which are oxidizing or have specific odor properties can now be detected as well as flammable gasses. Also, by having multielements on one chip, FIGARO can provide intelligent sensors with multiple output signals.

The equivalent circuit for each type of sensor is illustrated below in the basic measuring circuit with a special symbol and is represented by a sensor resistance (RS) and a heater resistance (RH). Each sensor requires two voltage inputs. Heater voltage (VH) is applied to an integrated heater to maintain the sensing element at the required temperature. A circuit voltage (V C) is applied to allow measurement of the voltage (V out ) across a load resistor (R L ) which is connected in series with the sensor. A common power supply circuit can be used for both VC and V H to fulfill electrical requirements which are specified for each type of sensor. The value of RL can be chosen to optimize the alarm threshold value or output voltage range for signal processing. The value of RL should be chosen to keep the power consumption of the metal oxide 2 ,,,,, Rs = (Vc-Vout) x RL Vout unit : mm (+) Heater Sensing material Substrate ,,,,, , Electrode GAS SENSOR 2 Sensing element VH Stainless steel gauze 11.520.2 GAS VC 3 1 Plastic cap (-) Lead wire 4.70.2 Lead frame Lead frame Pin connection Features 1 : Sensor electrode(-) 2 : Common(+) 3 : Heater(-) : -Simple structure : -Suitable for large volume and low cost applications RL 0.80.1 2.54 2.54 Configuration : -Single sided, 1 element Benefits The sensor resistance (RS) is calculated with a measured value of Vout from the following formula: o12.00.5 ,,,, 2.2mm (Vc-Vout)2 RS ,,, ,, , ,,,, 3.2mm Ps = , ,,,,, Model TGS 21XX Element type S1 Package type Plastic semiconductor (PS) below a limit of 15 mW.

This relationship is based on a logarithmic function. Sensitivity characteristics of Figaro sensors are shown in the following figures. In these figures, the sensor resistance values (Rs) are normalized according to the sensor resistance at specified conditions (Ro) for each model, and the Y-axis is indicated as sensor resistance ratio: Rs/Ro.

The microprocessor calculates the average value of the sensor resistance in ambient air over a certain period and renews the base level. This reduces influence from humidity, temperature and basic environmental changes. This method is effective for automatic controls in ventilation systems by detecting rapid changes in the atmosphere from the base levels.
