Electromagnetic Super-high Frequency Methods of Measurement
A number of physical limitations of resistive transducers' informational capabilities caused the search of new measurement means using electromagnetic fields of high and superhigh range of frequency to transfer information of non-electric values.
The major features of superhigh-frequency multiparameter measurement transducers (SMIP) are the following:
—— wavelength range of supply voltage is commensurate with transducer dimensions;
—— information source is presented by the reactive component of transducer input impedance;
—— the possibility of variation of the electromagnetic field relative to the object of study depending on the problem to solve;
—— commensurability of geometrical dimensions (or, frequently equality) of distributed SMIP and the object of study.
超高频电磁测量法
由于电阻传感器测取信息的能力受到很多物理限制，致使人们去寻求新的测量手段，例如利用高频和超高频电磁场传输非电量的信息。
超高频多参量测量传感器（SMIP）的主要特点如下：
——供电电压的波长范围与传感器的大小相称或相当；
——信息源由传感器输入阻抗的无功部分表示；
——电磁场可根据所要解决的问题相对于被研究物体进行改变；
——分布式SMIP与被研究物体的几何尺寸相称或常常相等。
Distributed SMIP enable the researcher to obtain information on the field distribution of a physical value along the object without continuous increasing the number of discrete transducers in informational systems.
At our institute SMIP are developed for analysing local strain fields, temperature and pressure fields. Constructively, for measuring these physical values SMIP in form of a strip or a wire with a cross-section less·than a few square millimeters are stuck to the surface along the profile of interest.
分布式SMIP可使研究人员在无需不断增加信息系统中离散传感器数量的情况下，获得关于某一物理量沿物体的场分布信息。
我院研制了分析局部应力场、温度场和压力场的SMIP。从结构上说，测量这些物理量的SMIP采用狭长带或线状形式，其横截面积小于几平方毫米，粘贴在感兴趣的外廓表面上。
Electrical signal at the output of secondary devices is proportional to the level of the measured physical value, and the additional parameter of the signal, e.g. lag time allows to identify the measured physical value at each point of the object along SMIP. SMIP may be also applied to solve such problems of aerodynamic experiment as the measurement of friction force as well as forces and moments.
二次仪表输出端的电信号同待测物理量的大小成正比，而电信号的附加参数，例如时间滞后量，则使我们能够辨别物体上沿SMIP系统每一点上的待测物理量值。SMIP也可用来解决像磨擦力测量以及力和力矩测量等等气动实验问题。
