| 摘 要： | 热电偶传感器具有性能稳定、结构简单、使用安全、价格低廉、测温范围广等特点,在液体火箭发动机地面试验中得到了广泛应用。由于输出信号小,在发动机试验的恶劣环境中若使用不当,则容易造成测量不准或测不到数据。针对目前测量中存在的问题,提出了热电偶传感器使用中应注意的一些关键技术和使用工艺要求。工程实践表明,按此工艺操作,热电偶的测量可靠性和测量精度明显提高。

| Abstract: | Thermocouple sensor has steady performance,simple structure,extensive measurement range.It is used extensively in liquid rocket engine ground experiment for its safe and cheap characteristics.Because of its low output signal,the measurement result of the thermocouple sensor is inaccurate or even without an measurement result if it is not used normally in the severe environment of engine experiment.This thesis aims at these problems in the measurement,discusses some key techniques and technical requirements ... |
