The invention relates to a differential pressure type stock bin under high-temperature and high-dust working conditions and a material level measurement control method, aiming at a high-temperature and high-dust-content stock bin, multi-point analog quantity differential pressure reverse blowing type transmitters are arranged at different heights, and a measuring device for converting a pressure value into a material level signal through judgment with a set value is adopted, so that discrete monitoring of the material level is realized; the feeding amount of the stably operated material is used as a reference feed-forward value, and the opening value of the discharging device is controlled, so that the measurement and fuzzy control of the material level of the high-temperature and high-dust material bin can be well realized. 一种高温高尘工况下的差压式料仓及料位测量控制方法，针对高温高含尘料仓，通过在不同的高度设置多点模拟量差压反吹式变送器，将压力值通过与设定值判断转换为料位信号的测量装置，实现料位的离散监测，以稳定运行的物料进入量作为基准前馈值，通过控制出料装置的开度值，能很好的实现高温高尘料仓料位的测量及模糊控制。
