| Abstract: | This system uses micro-flow gas thermal conductive sensor TCS208F for hydrogen volume fraction detection.The signal conditioning circuit and environment temperature control circuit in the external of the sensor are designed in order to achieve constant temperature detection.The weak signal outputed by the sensor is sent off through the measuring bridge.It is primarily amplified by the integrated chip AD708,secondary and amplified by the subtraction circuit.Finally the standard voltage signal is carried into... |
