飞机系统模拟试验中热电阻及其数字显示仪表的现场校准技术研究

在飞机系统地面模拟试验中．热电阻及其数字显示仪表在液压、飞控等试验系统中广泛使用。针对各试验系统中某些位置的热电阻及其数字显示仪表接线复杂，不便拆卸和传统计量方式的种种弊端等问题，提出了一种由现场计量炉、便携式测温仪和温度校准器等设备组成的现场校准系统。实现对热电阻及其数字显示仪表的现场整体校准，同时亦可实现对热电阻及其数字显示仪表的分部校准，避免了拆卸和安装，提高了工作效率，具有实用价值。

The Field Calibration Technology Research of Thermal Resistance and Digital Display Instrument in Aircraft System Simulation Test

In aircraft system ground simulation test, thermal resistance and digital display instrument are widely used in the hydraulic, flight control and other experimental systems. Aiming at the problems of some thermal resistance and digital display instrument wiring complexity, inconvenient disassembly in each test system and the shortcomings of traditional measurement way, a field calibration system which is consist of field metrology well, portable thermometric instrument and temperature calibrator is presented. The field calibration system realizes thermal resistance and digital display instrument field whole calibration, also can calibrate thermal resistance and digital display instrument by segments. It avoids dismantling and reassembling, improves the work efficiency and has strong practicability.
