REMOVABLE MAGNETOSTRICTIVE SENSOR WITH AUTOMATIC CALIBRATION Russian patent published in 2018 - IPC G01R33/18 

FIELD: measuring equipment.

SUBSTANCE: group of inventions refers to instrumentation, and more particularly to the magnetostrictive sensor including a removable probe with automatic calibration. Magnetostrictive measuring device comprises a probe, which includes a tube having a proximal end and a distal end. In this tube a magnetostrictive wire is located. Adapter at the tube proximal end includes a probe circuit comprising a magnetostrictive wire exciting circuit, a sensing element, a preamplifier, and a memory circuit storing calibration parameters for this probe. Instrument housing includes a control circuit. Between the instrument housing and the adapter, a connector is conveniently located, containing conductors for the control circuit connecting to the probe circuit.

EFFECT: technical result is the possibility of the converter automatic calibration when it is used with different probes.
