Abstract:

The aim of this research is to construct and evaluate the performance of potentiometer tactile displacement sensor to measure different cross sectional shafts and to use this sensor in a developed computer system to assess its capability to measure different cross sectional of engineering parts.

The manufactured sensing systems is made of three major parts, the sensor analogue to digital convertor and the computer which analyzes the obtained data. In this research, three potentiometric tactile displacement sensors were implemented used with a working range up to 50/mm.

The principles of operation depend on the variation of the value of electrical resistance by changing the location of the sensor depending on the shape of cross section required to be measured . Many experimental have been carried out to calibrate the manufactured system, and many electrical resistance were used to many different engineering parts.The cinitial experiments work showed the following:

·        A deviation in value obtained by the system of the based fitting line at the linear displacement.

·        Using the classical calibration method, which means using all the working range which equals to 50 mm.
