Pressure Gauges
简 介
YEJ-101型矩形膜盒压力表适用于锅炉通风设备对铜合金不起腐蚀作用的和中性、无爆炸危险的气体的微压和负压进行测量。
YEJ-121型矩形接点膜盒压力表是适用于锅炉通风设备对铜合金不起腐蚀作用的和中性、无爆炸危险的气体的微压和负压进行测量并具有双二位调节(双线发讯)的作用，以实现位式调节或超限报警作用。
Brief Introduction:
YEJ-101 model rectangular membrane case pressure meter is applicable to measuremicro-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 bydual line), so as to realize position
