对某些不可接近的位置进行测量,往往成为难题,因为不可能用导线把传感器接到数据显示装置上。目前虽有一些装置,像适用于测量旋转机械的集流环和非接触测量用的光学高温计,但常常不能满足需要。在这种情况下,无线电遥测就成为一种传递数据的最好方法。在空间工业上无线电遥测已趋于成熟,自第二次世界大战以来,已广泛采用无线电遥测对飞机、火箭、导弹和卫星搜集数据和进行控制。已成为标准的FM/FM遥测,特别适用于空间高数据率、多路信息和多种输入信号的需
Measuring some inaccessible locations is often a challenge as it is not possible to wire the sensor to the data display. Some devices, such as current collectors for measuring rotating machinery and optical pyrometers for non-contact measurement, are often inadequate. In this case, radio telemetry becomes the best way to transfer data. In the space industry, radio telemetry has matured, and since the Second World War radio-telemetry has been widely used to collect and control aircraft, rockets, missiles and satellites. Has become the standard FM / FM telemetry, especially for space high data rate, multiplexing information and a variety of input signal needs
