根据系统灵敏度，确立了当系统噪声限为探测器噪声和背景两种情况下红外气体传感器中测量气室长度计算公式，并以实际系统计算为例，得出了ALM1217矿用红外甲烷传感器测量气室长度的具体值。为确定该类传感器测量气室长度提供了一定的理论依据。红外气体传感器中测量气室?..
According to the sensitivity of the system, the formulas for calculating the length of the gas chamber in the infrared gas sensor are established when the system noise is limited to the detector noise and the background. Taking the actual system calculation as an example, the measured gas of ALM1217 mine infrared methane sensor Room length of the specific value. In order to determine the type of sensor measuring the length of the gas chamber provides a theoretical basis. Infrared gas sensor in the measuring chamber?
