Abstract

PURPOSE: To prevent current flow measuring function to be lost abruptly, by providing such a mechanism that even at the time when a heat ray of Karman vortex value sensor breaks down, a new non-damaged section is utilized to resume making output.
CONSTITUTION: When line breakage occurred in some block of terminals A1W A4 of a vortex generator 2, an output of a bridge circuit 6 is held at a constant value and an ever-open contact 15b is closed. Because of this, a step motor rotates by one step, and a rotary switch 17 which is linked to the step motor shortcircuits a block between terminals A1 and A2. At this time, if the breakage occurs between A1 and A2, an output between A2 and A4 is detected, but if this was not the case, as an output of the bridge circuit 6 is still held at the constant value, the step motor 16 is further rotated by 1 step, and a block between A2 and A3 is shortcircuited. By detecting broken blocks of heat ray in turn in this manner, an output of a non- broken ray is taken out.
