宝德8175型超声波液位计,BURKERT流量计,宝德液位计8715型

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zui小电流及zui大电流时，分别代表电流变送器所标定的zui小及zui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*的抗干扰能力得到了广泛应用。
