Sensor Interaction as a Source of the Electromagnetic Field Measurement Error

Abstract

The article deals with analytical calculation and numerical simulation of interactive influence of electromagnetic sensors. Sensors are components of field probe, whereby their interactive influence causes the measuring error. Electromagnetic field probe contains three mutually perpendicular spaced sensors in order to measure the vector of electrical field. Error of sensors is enumerated with dependence on interactive position of sensors. Based on that, proposed were recommendations for electromagnetic field probe construction to minimize the sensor interaction and measuring error.

“…Итак, контроль параметров осуществляется непосредственно в установках с участием датчиков [28], [29], [31]. Таким образом, существует проблема агрессивности среды плавки металлов и помех в работе датчиков, порождаемых самими датчиками электромагнитного поля [32].…”
