Summary

Miniature Hall converters are made from heteroepitaxial structures of indium antimonide on semi-insulating gallium arsenide. They have very small dimensions (thickness between 150 and 300 μm). The working temperatures are between 1.5 1.5°K and 125 °C.

Description

Miniature Hall converters (MHC) have some significant differences in contrast to those presented on CIS markets:

• Miniature dimensions with thickness of 150 μm; MHC makes it possible to measure magnetic induction in thin gaps, for example, to measure magnetic induction in motor gaps (between the stator and rotor), traction relays, in magnetic conductor splits of defectoscopes, current sensors and much more;
• Capability of measuring magnetic induction at cryogenic temperatures, which makes it possible the use MHC in scientific research, space instrumentation production;
• Establishment of two- and three-component magnetometer probes, which makes it possible to measure gradients and vector of magnetic induction.
