Abstract
Abstract. A new kind of a modular multi-purpose robot system is developed to measure the spatial field distributions of very large as well as of small and crowded areas. The probe is automatically placed at a number of pre-defined positions where measurements are carried out. The advantages of this system are its very low influence on the measured field as well as its wide area of possible applications. In addition, the initial costs are quite low. In this paper the theory underlying the measurement principle is explained. The accuracy is analyzed and sample measurements are presented.
Highlights
In the context of electromagnetic compatibility, the knowledge of the electromagnetic field distribution in a certain plane or volume is often required
If the volume under test is too small, the robot cannot be placed inside. If it is much larger than the scanning area of the robot, the total measurement has to be divided into several parts
The belts get stretched a little bit when attaching heavy sensors. This influence can usually be ignored if using belts that are oversized with respect to the expected loads
Summary
In the context of electromagnetic compatibility, the knowledge of the electromagnetic field distribution in a certain plane or volume is often required. This information can be used to verify the efficiency of shielding measures or to calibrate field simulators, for example During such measurement campaigns, usually a large amount of data is collected for a lot of positions in the test area. If the volume under test is too small, the robot cannot be placed inside If it is much larger than the scanning area of the robot, the total measurement has to be divided into several parts. Such systems often are too big to speak of an movable measuring device. Rubber belts are used which are armed with fibreglass to ensure both tensile strength and a very small influence of the measurement system on the field to be measured
