一种应用于AD转换模块的恒温电路设计
资料介绍
研究一种恒温控制电路。以热敏电阻为温度测量元件,加热电阻加热的方法实现一种简单、稳定的恒温电路。当环境温度在-25℃-＋75℃变化时,恒温控制电路可以使恒温盒内的温度变化在±1℃,从而保证AD采样模块在一个恒定的环境中工作,最大程度减少了由于温度变化带来的高精度器件精度漂移。
This research is focused on a constant temperature control circuit. A simple stable constant temperature circuit is realized by using thermistor as temperature-measuring element and heating the heat resistor. When ambient temperature varies in the range of-25 ℃to ＋ 75 ℃,the constant temperature control circuit keeps temperature change in the thermostatic box within ± 1 ℃,thus ensuring that the AD sampling module can work in a constant environment and precision drift of high-precision devices caused by temperature change can be minimized.
