EN Magnetic field sensors, based on the Hall effect, in mass production currently have a standard operating temperature limit of 150°C. There are sensors designed for specific purposes that can function within a limited range of up to 225°C or even at the temperature of liquid nitrogen or liquid helium. The technology for the production of magnetic field sensors enabling operation in industrial conditions at temperatures significantly exceeding 225°C or in the full range of temperatures from cryogenics to elevated temperatures (reaching 350°C) has not yet been developed. In this letter, we present a reliable and high-quality magnetic field sensor that is capable of functioning under a wide range of temperatures. The sensor was developed using mainly the academic infrastructure of the Poznan University of Technology and can be suitable for industrial use.
