目前,在航空科研生产现场的温度设备上,大量使用着以热电偶、热电阻作为传感器的测温仪表,用于监视和测量设备温度变化的情况,以保证设备在工艺规程要求的温度范围内工作。如果测温仪表工作中出现量值不准确,就可能导致产品组织改变、超差、甚至报废,造成严重损失。因此,保证以热电偶、热电阻作为传感器的测温仪表量值的准确是航空产品质量保证的一项重要工作。组建中低温校准系统并定期对中低温仪表进行校准是保证其准确的有效方法。为了
At present, in the temperature research and production of aeronautical research and production site, extensive use of thermocouple, RTD as a sensor temperature measuring instrument for monitoring and measuring equipment temperature changes in order to ensure that the equipment in the process temperature range requirements jobs. If the temperature measurement instrument appears inaccurate magnitude, it may lead to product organization change, tolerance, or even scrapped, causing serious losses. Therefore, to ensure that the thermocouple, RTD as a sensor measuring the accuracy of the value of the instrument is an aviation product quality assurance an important task. The establishment of low-temperature calibration system and the regular calibration of low-temperature instruments is to ensure its accurate and effective method. in order to
