FIELD: measurement equipment.SUBSTANCE: invention represents an ultrasensitive intelligent magnetoimpedance sensor (MI sensor) with expanded range of working temperatures in the area. The sensor comprises a magnetoimpedance element (MI element) with two coils arranged one above the other, an analogue key, an amplifier, a temperature sensor, a microcontroller, a unit of a thermistor. The MI element with two coils makes it possible to expand a measurement scale, to perform calibration of the sensor. The microcontroller performs digitisation of data, controls all units of the sensor (MI element, analogue key, amplifier), performs mathematical data processing. The temperature sensor and the unit of the thermistor provide for operation of the sensor in a wide temperature range.EFFECT: increased functional capabilities of a MI sensor, expanded limits of a measurement scale and range of working temperatures, increased accuracy of measurements, collection of additional information about temperature.6 dwg |
