The paper presents a new approach to the design of a miniaturised displacement transducer for deep hole measurement. By exploiting the induced eddy current effects detected by chip coils, the sensor generates a frequency output signal. The sensor chip coil can be manufactured by the similar processes to those used for manufacturing a printed circuit board (PCB) which allows them to be miniaturised. The paper elaborates on the construction and mechanism by which the displacement is directly transferred to a frequency output. It also reports on the transducer, which uses two contact probes for transmitting the displacement to a non-contact sensing element. Experimental results demonstrate the stability, linearity, measurement range and accuracy of the sensor system. (C) 1999 Elsevier Science Ltd. All rights reserved.
