ことを特徴とする測定装置。A plurality of air nozzles facing the inner or outer circumferential surface of the object to be measured, a pressure detector that detects changes in back pressure of each air nozzle, and signal processing that processes each measurement signal output from the pressure detector. In the measuring device, the plurality of air nozzles are arranged at least diametrically in the same plane perpendicular to the axis of the object to be measured, and the air nozzles are spaced apart in the axial direction. Assemble, first
The set of air nozzles is a tool nozzle that corresponds to a common measurement position from one end to each of the different types of workpieces, and communicates with the pressure detector, and the second set of air nozzles is used for the first workpiece in the different types of workpieces. A third set of air nozzles is a dedicated nozzle that communicates with the pressure detector, and a third set of air nozzles is a nozzle dedicated to a second workpiece among different types of workpieces that communicates with the pressure detector.
A measuring device comprising a switching circuit that discriminates between a workpiece and a second workpiece and selectively switches the measurement signal of the first workpiece-dedicated nozzle or the second workpiece-dedicated nozzle to be valid.
