差压变送器是工业实践中最为常用的一种传感器,其广泛应用于各种工业自控环境,涉及水利水电、铁路交通、智能建筑、生产自控、航空航天、军工、石化、油井、电力、船舶、机床、管道等众多行业。压力变送器厂家是用于测量液体、气体或蒸汽的液位、密度和压力,然后将压力信号转变成4~20mADC信号输出。压力变送器要有电容式压力变送器和扩散硅压力变送器,陶瓷压力变送器,应变式压力变送器等。

压力变送器根据测压范围可分成一般压力变送器和微差压变送器,负压变送器三种。差压变送器测量的是气体或液体的压力之间的差异,是一个相对量。压力变送器测量单个气体或液体的压力的大小,并且是一个量。使用(use)的角度来看,压力差有两个输入(shūrù)管被用来介绍两个样品进行测试(TestMeasure),以获得他们的差压;压力只有一个口,通常使用的是从采样位置(position )导致测量管到变送器和直接采样点压力测量;差压变送器通常是由两个采样位置表管连接到发射机(应用:通信、电视、广播、雷达)胶囊,发射机测量后的响应两个点之间的压力差.压力变送器根据被测介质的压力不同分为压力变送器,压力变送器,微差压变送器,低、中、高差压变送器,高静压(static pressure)变送器等,它把压力信号变成标准电信号远传,可进行压力、流量(单位:立方米每秒)、液位的测量。
