Exd IICT6进口高压压力开关【J120-494】防爆UE开关现货 西安UE***
控制泵起停
开关控制泵的起停。工艺，一般由泵做一个动力源，将特定区域内的压力控制在(a，b)区间内，是否到达a、b点由开关输出开关量信号。
方案一：H100-15731~15737,死区可调，SPDT输出，开关点的开闭可直接控制泵的起停。劣势：无现货，设定点易漂移可达设定点的10%现场需有校验能力，优势：中间不需要加逻辑控制器，也不会出现开关点死区>b-a区间所带来的问题。
方案二：J402，2个SPDT输出。劣势，要加逻辑继电器两点同时动作时输出信号，优势：b-a>c时候不漂移。
锅炉燃烧控制
通常用到3类UE开关
1. 燃油管道输送燃油压力低，设定值通常为2Mpa左右。型号H100-193
2. 炉膛正负压力控制，设定值±1.5kpa左右。型号H100-521
3. 焦炉煤气管道压力低，设定值2kpa下报，型号J120-521或451.对开关死区要求不严格，因为报警后管道压力会归零，不需要开关反复重复动作。且小感压孔经验告诉我们使用起来没大问题。
