With this publication a coil identification algorithm inside a high precision triangulation sensor for residual shorts measurement of coiling materials is presented. The sensor is a stand-alone system. A Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA) and a Microcontroller (MC) collect and process the data of the linear CCDsensors.The basic element of the sensor is a symmetrical arrangement of two laser emitters and their receiving optics. Due to this arrangement we get a stable thermal behavior of the sensor.Furthermore this paper gives some detailed information about the accuracy, resolution and the measuring range of the sensor. One industrial application is listed at the end of this paper.
ifl this paper we would like to present a new idea for measuring high precision tubes with an accuracy of +I10 rim. The most interesting values of the tubes are wallthickness, diameter, eccentricity and so on. The cycle of measuring is not more than 5 seconds inclusive teh complete tube handling. The prefered sensor concept is the triangulation technique with a matched sensor head.
With this publication a high-processing non-contact distance sensor for heavy accessible movable components in industrial machines and engines is presented. A lot of systems exist for distance measurement. Most of them have a rectangular casing and it is not possible to use them in every industrial environment.Another disadvantage is the slow signal processing which makes it impossible to use them for the signal processing of highspeed motions. The common CCD sensors can only run with ca 5kHz measuring rate. Additional the relation of resolution and measurement range is too low for the actual used triangulation sensors.Furthermore this paper gives some detailed information about the accuracy, resolution and the measuring rate of the new sensor.
