Workshops at ilis gmbh

[b]Februar 19th 2004, StrainMatic Information Day[/b] Presentation of the StrainMatic XP at the ilis gmbh in Erlangen. If you are interested in joining the StrainMatic Information Day, you can order application forms directly at the ilis gmbh. about: Function The breaking strength of glass, especially of curved bodies such as containers and other hollow glassware, is determined very much by residual stresses, which depend essentially on the forming process, annealing and the wall thickness distribution. Constant testing of the residual stresses after the annealing process is therefore an important part of quality control in production. The StrainMatic® XP working according to the Sénarmont principle facilitates the automatic and objective measurement of the birefringence and counters the disadvantages of the previously used manual and therefore subjective methods. Features and Benefits Automatic determination and color-coded display of stress distribution over the whole measuring range Calculation of polarization angle, temper grade (in accordance with ASTM C-148), optical retardation and stress Exact consideration of the glass thickness Definition of limiting values for a good/bad evaluation Article-related entry and storage of all parameters Optional database for the automatic archival of all measuring results Integrated industrial PC with intuitive touch-screen Technical Data Housing anodized aluminum Operation integrated industrial PC with touch-screen Sample compartment approx. 450 x 450 x 350 mm (HWD) Height adjustment 50 - 450 mm, motorized Image size approx. 40 x 30 mm to 200 x 150 mm Image resolution 640 x 480 pixels Measuring window variable: rectangular, round or elliptical Measuring step width variable: 5, 10, 15, 30, 45 or 90° Measuring results polarization angle (°), apparent/real temper grade (ASTM), optical retardation (nm), normalized retardation (nm/cm), stress (MPa) Measuring range -90° to +90° (-280 nm to +280 nm) Measuring resolution variable: 0.05° to 1° Reproducibility < ±1° at 0.25° measuring resolution Data Interfaces 100 MBit Ethernet, 2 x USB 1.0 Power supply 230 V, 50 Hz or 115 V, 60 Hz Working temperature 10 - 35 °C, non-condensing Dimensions approx. 1150 x 520 x 560 mm (HWD) Weight approx. 70 kg
