差压变送器性能达不到要求怎么办?

文章出处:华仁仪表 发表时间:2019-04-03 10:45

 

随着仪表技术的进步,各种品牌差压变送器都向着高精度、智能化方向发展。然而技术的进步为设计者们带来了一个误区:人们在选择变送器时,往往注重其自身精度,而忽视了影响测量精度的其它因素。实际上,用户真正需要的是能够正确反映被测值的真实值——测量精度,而非变送器自身的精度。影响变送器测量精度的因素很多,有些因素还与环境条件及安装方式相关。因此,在设计时,产品自身精度并不能保证实际的测量效果,设计者们不但要在选型时考虑到实际环境对产品精度的影响,也要注意在安装时尽量减小对变送器精度的影响。那么,都有哪些因素会对差压变送器亚博足球app造成影响呢?仪控君为大家整理了以下几点~

量程比的影响

差压变送器的量程比是指在满足精度要求的情况下变送器所能测量的最大值与最小值的比。一般情况下,量程比越大,其测量精度就越低 , 压力变送器亚博足球app量程比大,有很多好处,这样一台仪表调校后,可以用在多个不同的场合。但是实际中量程比调的太高,会带来很多测量稳定性的问题。
