塑料浮球液位计

浮球液位计适用于工业和民用建筑、水池、水箱、集水坑和工业槽罐等测量各种介质的液位，广泛应用于化工、冶金、电力、造纸、食品及工业污水处理等部门。　　特 点　　浮球液位计能有效克服悬浮物、泡沫等形成的假液位浮球经配重可测两种液位的介质成本低，可靠性高。　　技术参数　　测量范围：0-0.5m至0-4m（4m以上选静压式为宜）　　电源：24VDC(15-36VDC)　　输出信号：4-2OmADC二线制（带HART协议）　　测量精度：±1%（H≥1.0m时）　　±1.5%（H＜1.0m时）　　环境湿度：-10-55℃湿度≤95%无强烈震动　　介质温度：-20-120℃　　介质压力：0-600KPa（特殊订货部超过2.5Mpa）　　介质比重：≥0.4g/cm、粘度：≤0.05PaS　　工作原理　　磁性浮球比重小于0.5，可漂浮于液面之上并沿导杆上下移动。导杆内装有电感测量元件，在外磁场作用下产生正比于液位变化的电阻信号，由电子单元转换成4-20mA或其它标准信号输出，模块有过流保护和反接保护等功能。液位变送器传感器是通过测由液位产生的压力来定液位度的。液体压力用公式=o+рgh表，其中：o为液面上部气压，р为被测液体密度，H为液体度，g为重力速度（常数）。当o保持变时，则压力取决于密度和液位两个变。当液体密度为一定值时，液位将与压力成线性关系。这一压力作用在变送器扩散硅压力传感器的感压面上，通过传感器的压阻效应，将液柱压力转换成电压号。这一号经放直接转换成4~20mA。若液面上部气压发生变化，压力传感器将受到如同液位变化一样的影响。UD-91采用了通透气电缆设计方法，将外界气压导入传感器感压面的另一侧。从而了因气压
