嵌入温场型温度记录仪的设计与实现

Design and realization of embedded type temperature logger

针对医疗灭菌锅、高温消毒柜和培养箱等工作时需密闭操作空间的情况,采用耐高低温冲击的电路系统,研制一种投入式、微功耗、具备防水功能,能在-40~140℃环境中长时间使用的温度记录仪。实际应用结果表明:该温度记录仪测量精度高、耐温性强、操作方便,适于食品药品加工、医疗卫生保障和冷链冷藏处理等行业的测温应用,具有较好的应用前景。

The embedded type temperature logger which is waterproof and micro- power is designed for detecting temperature of the devices that are operated in a confined space, such as medical sterilization pot, heat sterilization cabinets, incubators, etc. The temperature logger is developed with test circuit system which can bear high and low temperature, and it can work in-40℃ to 140℃ environment for a long time. The results show that the high temperature logger can measure the temperature accurately for a long life, and it is easy to use in broad applications, such as, the food and drug processing, medical and health protection,refrigeration processing, an so on.
