A tuning method, device and equipment for a linear variable differential transformer

Abstract

The invention discloses a tuning method, device and equipment for a linear variable differential transformer, and a computer readable storage medium. The method includes the following steps: when thelinear variable differential transformer LVDT needs to be tuned, if tuning that needs to be performed is not first tuning of the LVDT, a current machine code value of the LVDT is obtained; whether a difference values between the current machine code value and a standard machine code value is within a preset error range is judged, if yes, it is determined that the LVDT is not required to be tuned,and if not, positions of the current machine code value and the standard machine code value separately corresponding to the LVDT are determined, the LVDT is adjusted from the corresponding position ofthe current machine code value to the corresponding position of the standard machine code value, and the tuning of the LVDT is completed, wherein the standard machine code value is the machine code value of the LVDT after the first tuning is completed. The method is simple in operation, and the tuning of the LVDT can be completed without professional personnel; and the reliability of the tuning is improved.

Description

technical field [0001] The present invention relates to the technical field of linear variable differential transformers, and more specifically, to a setting method, device, equipment and computer-readable storage medium for linear variable differential transformers. Background technique [0002] LVDT (Linear Variable Differential Transformer) is a linear variable differential transformer, which belongs to a linear displacement sensor. It can be used to measure accurate data such as elongation, vibration frequency, amplitude, thickness and expansion of objects, and is widely used in steam turbine valves. Bit opening detection. LVDT consists of an iron core, three coils and a casing, such as figure 1 As shown; where, e1 is the excitation coil, e21 and e22 are two feedback coils, the iron core is rigidly connected with the piston rod of the oil motor (the stroke of the piston rod corresponds to the opening of the main steam valve of the steam turbine); when the piston rod of ...
