MULTICHANNEL DEVICE FOR MEASURING AND RECORDING LINEAR DISPLACEMENTS

摘要

The proposed multichannel device for measuring and recording linear displacements contains a strain-gage or electromagnetic displacement transducer and the transducer signal converters, the number of which corresponds to the number of the measurement channels of the device. The displacement transducer contains a unit for converting the linear displacement into the angular displacement of the coded disk and an optoelectronic sensor with a pulse output signal for measuring the angular displacement of the disk. The pulses of the output signal of the displacement transducer are read according to a specified program simultaneously in all the measurement channels .
