非标准化传感器信号调理的一种新方法

New method for signal conditioning of non-standardized sensors

以非标准化热电阻为例,介绍了非标准化传感器如何与标准化传感器信号调理电路相匹配的一种方法。这种匹配方法的实质是充分利用测量系统的数据处理功能,通过软件来补偿非标准化传感器与标准化传感器之间的差异。它有效简化了测量系统的硬件,缩短了开发周期,提高了系统的可靠性和稳定性。

To take the signal conditioning of non-standardized thermal resistance on PCB board used in the lowcost PCR chip array control system as an example, a new method for the signal conditioning of non-standardized sensors is studied using standardized sensor signal conditioning circuits. The real of this method is to compensate the difference between the characters of non-standardized sensors and the standardized sensors through the software making use of the dada processing function of measuring system. The hardware of measuring system can be simplified and its reliability and stability can be improved and the time needed to design the measuring system can be also reduced effectively to use the method.
