1. The furnace pressure shall be measured by "t" or tubular pressure sensor specified in GB / T 9978.1. 

　　2.测量仪器的精度为±2.0pa。 　

　 2. The accuracy of the measuring instrument is ± 2.0pa. 

　　3.炉内压力每1min记录一次，记录设备的精度为1s。 

　　3. Record the pressure in the furnace once every 1min, and the accuracy of the recording equipment is 1s. 

　　4.压力传感器不应放置在受火焰冲击的地方或烟气排放通道内。当压力通过炉壁到达炉外，到达炉内时，即炉内压力与炉外压力相对于同一高度时，应处于同一水平面上。当使用“T”压力传感器时，“T”支路应水平。 　

　4. The pressure sensor shall not be placed in the place impacted by the flame or in the flue gas discharge channel. When the pressure reaches the outside of the furnace through the furnace wall and reaches the inside of the furnace, that is, when the pressure in the furnace and the pressure outside the furnace are relative to the same height, they should be on the same horizontal plane. When using the "t" pressure sensor, the "t" branch should be horizontal. 　

　5.至少应使用3个压力传感器。一个放置在理论地面100毫米范围内，一个放置在门或窗帘高度三分之二的100毫米范围内，一个放置在门或窗帘顶部100毫米范围内。 

　　5. At least 3 pressure sensors shall be used. One is placed within 100 mm of the theoretical floor, one is placed within 100 mm of two-thirds of the height of the door or curtain, and one is placed within 100 mm of the top of the door or curtain.
