使用环境 /Use environment

● 周围空气温度不高于 +40℃，不低于 -5℃，并且 24h 内其平均温度不高于 +35℃；
● 大气条件：空气清洁，相对湿度在最高温度为 +40℃时不超过 50％，在较低温度时允许有较高的相对湿度，例如 +20℃时为 90％，但应考虑到温度变化，
有可能会偶然地产生凝露；
● 海拔高度不超过 2000m；
● 本装置适应于以下温度的运输和储存过程：-25℃至 +55℃的范围之间，在短时间内 ( 不超过 24h) 可达 +70℃，在这些极限温度下装置不应遭到任何不
可恢复的损伤，而且在正常条件下应能正常工作；
● 如果上述使用条件不能满足时，应由用户和制造厂协商解决；
● 当本装置使用于海上石油钻采平台和核电站时，应另行签订技术协议。
● The ambient air temperature is not higher than +40℃ , not lower than -5℃ , and the average temperature within 24 h is not higher than +35℃ ;
● Atmospheric conditions: air is clean, relative humidity is not more than 50% at the highest temperature of +40℃ , and higher relative humidity is
allowed at lower temperatures, for example, 90% at +20℃ , but temperature changes should be considered. , it is possible to accidentally produce
condensation;
● The altitude does not exceed 2000m;
● The device is suitable for transportation and storage at the following temperatures: between -25℃ and +55℃ , in a short time (not more than 24h)
up to +70℃ , the device should not be subjected to these extreme temperatures Any unrecoverable damage and should function properly under
normal conditions;
● If the above conditions of use cannot be met, it should be resolved by the user and the manufacturer;
● When the device is used in offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.
