ELOVIS GMBH - 01.04.2007µSpeed-product informationGeneral Description®The µSpeed Sensor is a LASER-DOPPLER-Velocimeter for non-contact speed and lengthmeasurement to be used for all kinds of material with micro structured surfaces. Its simpleuse and robust design makes it suitable for a variety of applications in all kinds of industries.Speed and length of material with a length more than 5m can be measured long term with anaccuracy, better than +/-0,05%. The laser-doppler principle allows precise measurement onmost technical surfaces. The unit’s compact design makes it also suited for confined spaces.There are versions available, for up to 60m/s [11800f/mn] and stand off distances between120mm [4,7in] and 500mm [19,6in]. In addition, application-specific modifications andhousing protections as well as cooling devices can be asked for.µSpeed is also available in a certified form with the certification of the national metrologyinstitution of Germany (PTB – Physikalisch Technische Bundesanstalt, Braunschweig).Measurement PrincipleUsing two laser beams a stripe pattern is projected onto the object. The intensity of thereflection is modulated by the movement of the object and detected by the sensor. Thefrequency of the intensity modulation is proportional to the velocity of the object and thus tothe doppler frequency. There is no need for markings or reference points on the object.ApplicationsSpeed and length measurement for metals, paper, timber, textiles, non-woven, plastics, rubber web material, tapes, pipes, sheets, film, wire, cable, goods in pieces cutting length, process control, positioning, dosing, production data acquisition speed measurement for process control purposeTechnical Specificationsspeed range 0m/min...3600m/min [0ft/mn…11800ft/mn] *1)typical accuracy 0,05% *2)stand off distance 120mm [4,7in] +/- 5mm (+/- 20mm) [0,12in (+/-0,7in)]depfh of field 240mm [9,4in] +/- 10mm (+/- 40mm) [0,24in (+/-1,5in)]500mm [19,6in] +/- 20mm (+/- 80mm) [0,36in (+/-3,1in)] *3)interfaces1x RS 232 unidirectional for printer1x RS 232 bidirectional for PCI²C Bus for external keyboard or special applicationsanalog output0...4 V (programmable)impulse output1 ... 10000 Impulses/m (programmable)optical isolated outputs stop contact, pre-stop contact, alarmLASER diode 25 mW / 780 nm (class 3b)power supply230V / 50-60 Hz , 110 V / 50-60 Hz*1) Valid for µSpeed-S1 to – S60*2) Valid for lengths more than 5m (1σ) / >10m (2σ) / >20m (3σ) see also figure on page 4*3) µSpeed adjustment at the extreme range of values in round brackets may reduce measurement accuracy► Specifications are subject to change without notice.page 3/22

ELOVIS GMBH – 01.04.2007µSpeed-product informationImpulse Processing µSpeed-IMP certified by national metrology institution PTB applied for patentby a external encoder (contact wheel plusencoder that in most cases is alreadymounted to the machine). Hereby µSpeed-IMPdetects the direction as well as start and stopof the material movement (not machinemovement). In addition speed below themeasurement limit of µSpeed is measured byµSpeed-IMP. As the external encoder isgetting continuously calibrated by µSpeed, dayto day use problems as well as material andthickness changes won’t affect themeasurement. By using this configuration thecomplete measurement system is long termstable and long term calibrated.DescriptionµSpeed-IMP provides four functions:a.) direction recognitionb.) start and stop detectionc.) low speed measurementd.) pulse outputBy the use of µSpeed-IMP the signals of anexternal pulse generator device areprocessed to achieve the functions a, b andc. The pulse generator device can be either aencoder, which is driven by contact wheel orby transporting cylinder, or directly by aelectric drive. The pulse output function (d)operates without any other external deviceand enables µSpeed to send quadraturepulse signals to replace contact tachometers.µSpeed-IMP is certified by the nationalmetrology institution PTB (Germany) and hasbeen applied for patent.For achieving the function a, b and c, twoshifted by 90° pulse input signals arenecessary, which in general will be providedConnectionThe fast and easy connection with µSpeed-IMP is done by plugging in the included indelivery 9-pole Sub-D cable in the µSpeed TTLI/O. The external encoder has to be connectedto the corresponding clamp (channel A,channel B) of the µSpeed-IMP. See Figure 1.The pulse output signals are at clamp 9, 10, 13and 14. µSpeed-IMP is designed to bemounted by top hat rail. Similarly the µSpeed-IMP has to be connected to the power supply(carried out by 24V auxiliary supply). TheGrounding of the external encoder has to bethe same as for the IMP unit (important: similarreference ground).12345678910111213141516InputInput------OutputOutputOutputSupplyOutputOutputOutputSupplyVISIONETImpulse-Processing µSpeed-IMPImpulse AImpulse Bn.c.n.c.n.c.n.c.n.c.n.c.Channel /AChannel /BImpulse /N24VChannel AChannel BImpulse N0VTable 1: Connector pin assignmentpage 14/22

The data selection can be done bychoosing the memory file number or thememorization date of the data file.The µSpeed-LM long-term memory is a flash-EEPROM with a capacity of more than 50000data files.DescriptionThe µSpeed-LM long-term memory electronicboard (ring memory) is designed to beintegrated into the µSpeed processing unitand is used for memorization of up to 50.000measurement values. The Measurementvalues can be read out via serialinterface.and by laptop, PC or any superiorhost computer.One data file memorizes not only themeasurement value “Length” itself, but alsothe running memory file number, the date andhour of the measurement, the user name aswell as the failure flag which tells about thevalidity of the measurement value.Additionally a shift performance counter isimplemented into µSpeed-LM, whichmemorizes the performance of up to 6working shifts. By this counter, the productionvolume and the total lengths of each shift canbe memorized and then analyzed by aproduction data analyze software.The memorized data can be selected andisplayed by the operator menu of theµSpeed processing unit and then be sent byserial interface to an external computingµSpeed-LM memorizes the data in a cyclicalway, that means that if the memory capazityhas been reached, the oldes data file will beover written by the newest data file and soon.
