The well known TVO temperature sensors were irradiated by a gamma source up to the total dose of 0.1, 0.3 and 0.5 MGy. After these experiments the postradiation behaviour of the sensors was estimated. Besides, several tests of the TVO-carbon sensors with different specific sensitivities were carried out in the magnetic fields (parallel and perpendicular to the sensor package) up to 9 T in the t...

A novel optical current sensor based on microfiber knot resonator (MKR) with magnetic fluid (MF) as cladding is proposed and demonstrated in this paper. The operating principles, package technique and mounting method of the proposed sensor are introduced in detail. Moreover, the performances of the proposed sensor are demonstrated experimentally by detecting sinusoidal current with 50Hz and pul...

In this paper, a novel integrated structure is proposed in order to reduce the axial length of the high speed of a magnetically suspended motor (HSMSM) to ensure the maximum speed, which combines radial displacement sensor probes and the permanent magnet biased radial magnetic bearing in HSMSM. The sensor probes are integrated in the magnetic bearing, and the sensor preamplifiers are placed in ...

We report on the preparation of the first complete extreme temperature Hall sensor. This means that the extreme-temperature magnetic sensitive semiconductor structure is built-in an extreme-temperature package especially designed for that purpose. The working temperature range of the sensor extends from -270 °C to +300 °C. The extreme-temperature Hall-sensor active element is a heavily n-doped ...

A sensor network consisting of a number of palm-sized nodes with small electric and magnetic sensors has been proposed to monitor local electromagnetic activities in space plasmas. In the present study, a compact loop antenna system is designed and fabricated for use in sensor nodes that can capture magnetic vector fields from ELF to MF frequencies. The performance of the developed system is sh...

An easily applied and sensitive sensor for the detection of heavy metal ion residues based entirely on magnetic nanoparticle and oligonucleotide was developed. The tool is established on the relaxation of magnetic nanoparticles with different dispersion states. The target analyte, Hg ions, induce the aggregation of the MNP oligonucleotide probes. Accordingly, the light produced by the magnetic ...
