The robustness of system, the precise of temperature and pressure are observably improved as charge coupled, increase the amplification constant, decrease measure scope, etc. 采用电荷耦合、提高放大倍数、降低量程等误差修正技术,提高了系统抗干扰能力和温度、压力测量数据的精度;
Amplification conversion circuit, also known as the I/ F conversion circuit, when the rated constant current source signal is input into the amplification conversion circuit board, the corresponding frequency of the pulse signal output from the circuit board. 放大变换电路又称为I/F变换电路,即对电路板输入额定恒流源信号,则输出对应频率的脉冲信号。
