摘要
针对传感器在实际应用中存在输出信号较弱、且形式各异的问题,文中介绍一种可将压力、温度、频率等传感器的输出信号转换放大成标准的4mA—20mA或(1V—5V)信号输出的实际通用电路。
In view of different forms of faint signals that sensor outputs in practical application, a universal circuit is introduced in this paper that can transform and amplify the output signals of sensor, such as: pressure, temperature, frequency etc. Into standard output signals 4mA-20mA(1v-5v).
