Laser displacement sensor measures problem surfaces MatsushitaElectric Works has enhanced its range of measurement sensors byintroducing the new SUNX HL-C1 laser measurement system. Usingcharged coupled device (CCD) based technology, the sensor is ableto quickly and precisely inspect surfaces that have historicallyposed problems for analogue based non-contact measurementequipment. Black rubber and specular objects, including glass andwafers, can now be reliably and accurately measured using the newSUNX HL-C1 laser based measurement system.
Suitable applicationsfor the HL-C1 series include measurement of the eccentricity ofsteel shafts, co-planarity of IC pins, thickness measurement ofbrake discs and tyre tread measurement.
Containing an extremelycompact controller, the unit can accept the connection of up totwo measurement sensor heads.
This allows thickness measurementto be carried out easily using built in calculation functions.The sensor heads themselves are available in two styles: one formeasurement of diffuse type surfaces, including black rubber andmachined metal; and the other for specular objects such as glassand highly reflective surfaces.
Both styles offer two measurementranges and are capable of measuring to accuracies of 1micron.Configuration of the controller can be performed using either acompact touch screen console or PC based configuration softwarevia the built in RS232C communications port.
This port can alsobe used to transmit measurement data to a third party device, orthe internal decision-making capability can be utilised andinformation accessed via digital I/O connections.
