First contact-less, handheld optical micrometer

aerOel has launched hwS.1 – handy wire Scanner – a fully portable optical micrometer for non-contact measurement of wires, cables and other similar products. CCD technology, it uses two crossed linear sensors to automatically compensate positioning errors (patent pending). thanks to a powerful single chip microprocessor, the micrometer is linearised and compensated to obtain the maximum precision in the entire field of measurement, regardless of an accurate positioning of the wire. the measurement is started by pressing the trigger, which takes only a fraction of a second. the display provides the operator with interactive information to place the wire in the useful measurement area and displays the measurement result. all measurements are saved in the memory of the scanner, associated with the date, time and the number of machine. through a uSB connection, data can be downloaded to any PC. the battery is charged via the uSB connector with the supplied power supply. Battery life, with the micrometer always active, is approximately four hours. the scanner has been designed to fit into a special holder to be fixed on a machine, and this contains an rFID tag that identifies the machine, and which is read by the instrument at the time of measurement. the support allows the easy and quick placement of the scanner, and for the measurement of moving products, guaranteeing the maximum precision of measurements.

a single operator can monitor several lines/machines. at the end of the shift the stored data can be downloaded to a PC for reports to be checked, and for it to be printed. In addition to this basic function, which improves the sampling frequency, there are a number of other uses such as the set-up or the diagnosis of the process. an example is the process of enamelling copper wire: the modern lines start from the copper wire drawing and produce the finished product, applying and drying several subsequent layers of enamel, up to the finished wire which is collected in reels. even in the case in which the line is fitted with a laser gauge to check the final diameter before the reeling, the handheld optical micrometer can be useful in case problems arise, however readily detected by the on-line gauge. the next question is: where, at which stage of the process the ‘anomaly’ has occurred that led to the alarm.

support on each line, to periodically monitor the production of all machines with just one micrometer. the new micrometer hwS-1 enables an intermediate solution that can dramatically increase the frequency of checks inside a coil, with the non-contact technology making this possible. with the measurement of products in motion, there is no need to stop the process or wait for the end of a reel. the number of checks carried out inside a coil can be significantly increased. with small investment it allows you to equip each machine with a specially designed holder, and gives two additional advantages: • at the time of reading the diameter, the micrometer also reads the tag contained in the fixture. this lets you recognise and identify the position or the machine where you are measuring, and then combine the stored results with respective positions/machines • the positioning of the micrometer is greatly facilitated

It is therefore possible, mounting a
