JJG678-2007《催化燃烧式甲烷测定器检定规程》中,第5.3.3.2小节提供了一个计算公式(注:规程中的序号为(2),本文仍然沿用),用于将固定式仪器(甲烷传感器)的电信号值转换成甲烷浓度值,公式如下:G=(Gm-G0)/(Pm-P0)(Pi-P0)(2)式中:G——检测输出信号Pi对应的甲烷浓度,%CH4;Gm——输出电信号上限对应的甲烷浓度,%CH4(根据被检型号说明书给出固定值);G0——输出电信号下限对应的甲烷浓度,%CH4(根据被检型
JJG678-2007 “Code for the determination of catalytic combustion methane”, Section 5.3.3.2 provides a formula (Note: the order number (2), the text is still used), for fixed equipment (methane Sensor) is converted into methane concentration value, the formula is as follows: G = (Gm-G0) / (Pm-P0) (Pi- P0) (2) Where: G-- detection output signal Pi corresponding methane concentration ,% CH4; Gm - methane concentration corresponding to the upper limit of the output electrical signal,% CH4 (fixed value given according to the manual of the inspected model); G0-- methane concentration corresponding to the lower limit of the output electrical signal,% CH4
