BURKERT8220型电导率/电阻率传感器,宝德8220型电阻率传感器,宝德传感器
burkert两线制电流变送器的输出为4～20mA，通过250Ω的精密电阻转换成1～5V或2-10V的模拟电压信号.转换成数字信号有多种方法，如果系统是在环境较为恶劣的工业现场长期使用，因此需考虑硬件系统工作的安全性和可靠性。系统的输入模块采用压频转换器件LM231将模拟电压信号转换成频率信号，用光电耦合器件TL117进行模拟量与数字量的隔离。同时模拟信号处理电路与数字信号处理电路分别使用两组独立的电源，模拟地与数字地相互分开，这样可提高系统工作的安全性。利用压频转换器件LM231也有定的抗高频干扰的作用。
