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。
机械压力开关，为纯机械形变导致微动开关动作。当压力增加时，作用在不同的传感压力元器件（膜片、波纹管、活塞）产生形变，将向上移动，通过栏杆弹簧等机械结构，***终启动***上端的微动开关，使电信号输出。
