宝德数字式电导率变送器选型资料,BURKERT8226型电导率变送器
宝德数字式电导率变送器选型资料因其结构简单、稳定、压损小。量程范围宽等特点在液体测量中有着广泛应用。其原理是，当液体经过管道中的旋涡发生体时，所产生旋涡的振动频率与流速成正比。在涡街流量变送器中，以压电晶体或差动电容作传感器，将检测到的微弱振动信号放大、滤波、驱动后，输出其频率与瞬时体积流量成正比的脉冲信号，整个电路制成贺型印刷线路板，俗称放大板。这种变送器适用于分散模式，每台变送器配接1台基于频率检测的流量积算仪。近年来许多企业已逐步采用仪器分布管理模式，这就要求多个测量点的流量信号统转换成4－20mA，再送到计算机中集中临近和管理，因此出现了二线制的4－20mA涡街流量变送器，它是在原来放大板后面连块转换板而成，转换板由f / V和V / I电路组合，将原来放大板输出的频率信号转换成4－20mA输出。仪表系数非线性的影响传感器输出信号非线性是制约涡街流量变送器精度提高的zui重要因素，非线性造成各个流量区间表系数K不是常数。仪表系数定义为每立方米流量所发生的及冲数。变送器的非线性误差定义为（Kmax－Kmin）/ （Kmax＋Kmin）×100%。通常，输出脉冲频率信号的常量变送器的准确度标称只能达到1－2。而对于以电流输出在涡街变送器，由于电路中f / V环节的加入，基于RC充放电的f / V转换电路虽然有较高的分辨率，但线性及稳定性却满足不了较高精度的转换要求。
