液体危险化学品自燃温度检测电路的设计

摘要

The high accurate temperature detecting circuit based on K-type thermocouple is introduced. It is used for detecting the temperature inside the combustion chamber of the self-ignition temperature detector for hazardous liquid chemicals. The experiments show that the circuit meets the requirements of wide range and high accuracy for such detector. In addition, the design principle and method of this temperature detecting circuit can also be widely used in other temperature detection systems.%介绍了一种基于K型热电偶传感器的高精度温度检测电路，用于液体危险化学品自燃温度检测仪燃烧室内温度的检测。试验表明，该电路满足液体危险化学品自燃温度检测仪对其测温范围广、精度高的要求。同时，该温度检测电路的设计原理与方法也可以广泛应用于其他温度检测系统中。
