水位温度测量

High Accurate Measurement of Water Level and Temperature

文中利用片内带可编程增益放大的16位模数转换器件AD7705,采用普通的的温度和压力传感器,研究并实现对水位及温度的高精度测量,并且测量系统电路简单,运行稳定可靠。

With the utilization of analog-to-digital converter Ad7705 which is integrated on-chip programmable gain ampli- fier, ordinary pressure and temperature sensor, A new way to measure water level and temperature with high accuracy is re- searched and realized in the article. Moreover, the measure system is of simple circuit and high reliability.
