宝德8175型超声波液位计,BURKERT流量计,宝德液位计
宝德8175型超声波液位计抗干扰能力极差，线路损耗的破坏,谈不上精度有多高,有时输出的直流电压上还叠加有交流成分，使单片机产生误判断，控制出现错误，严重时还会损坏设备，输出０－５Ｖ不能远传，远传后线路压降大，精确度大打折扣。现在很多的ADC,PLC,DCS的输入信号端口都作成两线制电流输出型变送器4-20mA的,证明了电压输出型变送器被淘汰的必然趋势。宝德8175型超声波液位计的输出范围常用的有0～20mA及4～20mA两种，电流变送器输出Z小电流及Z大电流时，分别代表电流变送器所标定的Z小及Z大额定输出值。
BURKERT下面以测量范围为以0～１００Ａ的电流变送器为例进行叙述。对于输出0～20mA的变送器0mA电流对应输入０Ａ值，输出4～20mA的变送器4mA电流对应输入0Ａ值，两类传感器的20mA电流都对应１００Ａ值。宝德8175型超声波液位计大多为电压输出型，即将测量信号转换为0-5V电压输出，这是运放直接输出,信号功率<0.05W,通过模拟/数字转换电路转换数字信号供单片机读取、控制。但在信号需要远距离传输或使用环境中电网干扰较大的场合，电压输出型传感器的使用受到了极大限制，暴露了抗干扰能力较差,线路损耗破坏了精度等等等缺点，而两线制电流输出型变送器以其具有极高的抗干扰能力得到了广泛应用。
