Method and apparatus for detection of LVDT core fallout condition |
摘要 |
A method includes measuring a first voltage (VA) across a first sensing coil of a linear variable differential transformer (LVDT) and measuring a second voltage (VB) across a second sensing coil of the LVDT. The method also includes signaling a core fallout condition in response to (i) determining that a ratio of VA and VB is within a specified range of a value of one and (ii) determining that a sum of VA and VB is less than a sum of VA0 and VB0 by more than a specified amount. VA0 and VB0 are minimum voltages across the first and second sensing coils of the LVDT, respectively, when a core of the LVDT is in the LVDT. |
