description The utility model relates to a Barkhausen grinding burn detecting device based on temperature compensation and belongs to the technical field of burn detection for a ferromagnetic material workpiece. The utility model aims to solve the problem of the present Barkhausen burn detecting device for a ferromagnetic material that a measuring result is incorrect under the influence of environment temperature. An output end of a sine driving signal of a sine-wave generator of the detecting device is connected with an input end of a driving signal of a power amplifier; an amplifying signal outputted by the power amplifier is used as the driving signal for a first Barkhausen noise sensor and a second Barkhausen noise sensor; noise signals outputted by the Barkhausen noise sensors pass through a pre-amplifier, a band-pass filter and a main amplifier and then are inputted to a detector. The Barkhausen grinding burn detecting device based on temperature compensation is applied to the grinding burn detection for the ferrom
