很多用户选择压力测量产品的时候,经常不知道该选用压力传感器还是压力变送器,有的时候还经常混淆着用,当然这就起不到好的测量效果了。压力传感器与变送器之间到底有着怎么样区别和联系å‘? </p> <p style="text-indent:2em;"> 压力传感器是将压力转换为电信号输出的传感器。通常把压力测量仪表中的电测式仪表称为压力传感器。压力传感器通常专指是非标准mV信号输出的元件级产品,是压力变送器的核心元件,由于信号的非标准性,用户使用时需要进行压力标定和设计专门的信号处理电è·?由于信号微弱,距离较长时需要增加放大器。压力传感器一般由弹性敏感元件和位移敏感元件组成。弹性敏感元件的作用是使被测压力作用于某个面积上并转换为位移或应变,然后由位移敏感元件或应变计转换为与压力成一定关系的电信号。压力是自动化生产过程和航天、航空、国防工业中的重要参数,不仅需要对它进行快速动态测量,而且还要将测量结果作数字化显示和记录。因此压力传感器是极受重视和发展迅速的一种传感器ã€?</p> <p style="text-indent:2em;"> 压力变送器从书面意义上也属于压力传感器,但是其输出信号为标准通用的信号,å¦?åˆ?0mAï¼?åˆ?V等,可以远距离传送,并且可以与标准仪表配套。同时其压力值已经进行过标定,用户只需通过仪表的量程设定即可使用。压力变送器的作用是把压力信号传到电子设备,进而在计算机显示压力。其原理大致是:将水压这种压力的力学信号 转变成电压或电流这样的电子信号ã€?</p> <p style="text-indent:2em;"> 压力和电压或电流大小成线性关系,一般是正比关系。所以,变送器输出的电压或电流随压力增大而增大,由此得出一个压力和电压或电流的关系式,便于以后计算压力大小ã€?</p> <p style="text-indent:2em;"> 压力传感器和压力变送器都是工业上重要的压力测量工具。随着传感器技术的发展,两者的性能都得到改善,应用范围也越来越广泛ã€?</p> <p style="text-indent:2em;"> 价廉物美、德国品质、中国价位、美国效çŽ?</p> <p style="text-indent:2em;">
