ADMISSIBILITY DIAGNOSTICS OF USING A FOERSTER PROBE AS PART OF A MAGNETOMETER
(pp. 40-49)

Abstract. We have discussed a diagnostics method to assess the admissibility of using a Foerster probe as part of a magnetometer. The diagnostics is based on the compatibility analysis of the magnetic field (MF) induction (B) conversion by a Foerster probe with the parameters of a specific series of Foerster probe output signal converters (OSC). As a reference source of MF, we have used the Earth’s MF. The analysis uses a Foerster probe magnetometer designed according to the MF compensation method in the Foerster probe core piece. The subject of our analysis is the value of the OSC output signal under normal climatic conditions (NCCs), when the Foerster probe is exposed to extreme temperatures. Following the diagnostics, we have made a YES/NO decision on the admissibility of using a Foerster probe with OSCs of this series. As OSC parameters, that limit the use of a Foerster probe, we have adopted the values of the minimum and maximum codes of a digital-to-analog OSC converter, as allowed by relevant documents. The first two diagnostics stages are carried out with inductions of ±Bcon under NCCs, taking into account the Foerster probe zero offset. In this case, Bcon ˂ Вmax, where Вmax is the Foerster probe’s working range. Two subsequent diagnostics stages are carried out using the calculated and experimental characteristics, taking into account the Foerster probe zero offset under effect of extreme temperatures of different signs. We have demonstrated the temperature error specifics and presented the diagnostics algorithm.

Keywords: foerster probe diagnostics, magnetometer parameter control, foerster probe magnetometers, foerster probe characteristics.
