YEJ-121型矩形接點(diǎn)膜盒壓力表是適用于鍋爐通風(fēng)設(shè)備對(duì)銅合金不起腐蝕作用的和中性、無(wú)爆炸危險(xiǎn)的氣體的微壓和負(fù)壓進(jìn)行測(cè)量并具有雙二位調(diào)節(jié)（雙線發(fā)訊）的作用，以實(shí)現(xiàn)位式調(diào)節(jié)或超限報(bào)警作用。
Brief Introduction:
YEJ-101 model rectangular membrane case pressure meter is applicable to measure micro-pressure and negative pressure of neutral gases without danger of explosion, which cause no erosive attack on copper alloy.
It is also applicable to measure micro-pressure and negative pressure of neutral gases without danger of explosion in boiler draft equipments, which cause no erosive attack on copper alloy. In addition, it has a function of dual two-position adjustment （message sent by dual line）, so as to realize position
