Stresstter 6

The Stresstter 6 device enables fully automatic measurement of flat stress in glass sheets. The outcome of the measurement is plotted in the form of a curve showing flat stress values and temperature with respect to the width of glass sheet measured. Measurement of the stress and temperature values is conducted at various points across the glass sheet. The flat stress vector measured in the panel is oriented in the direction of the glass flow on the production line. Stresstter 6 works reliably under regular operating conditions in a manufacturing building, there is no need to lower the lightning in the measurement area or implement any special measures. The flat stress values are measured by Stresstter 6 with high accuracy and guaranteed repeatability.

Apart from clear glass, this measurement method can also be applied to patterned glass or wired glass. The device is provided with an automatic calibration system, which makes calibration very easy. Depending on the actual installation, Stresstter 6 can operate in on-line mode, measuring stress directly on a production line, or even off-line, outside the production line in manufacturing plant. In this case, the device is usually installed between the air cushion tables facilitate the manipulation of the measured glass sheets beneath the device.

Stresstter 6 is fitted with an LCD touch monitor to enable interaction with its operator. The monitor shows a clearly legible menu as part of the user interface provided in the software application to control individual functions of the system. After entering basic data about the test to be conducted and a testing subject, the operator launch the automatic measuring cycle. The optical measurement system moves across the glass sheet to measure flat stress. The measurement values also include the glass surface temperature. When the measurement finishes, the system performs an evaluation of the data rendered. The system issues a test report and the screen displays graphics representing the range of values measured, as well as temperature. The integrated program equipment contains tools for viewing test reports previously saved, together with graphs plotted using the values of flat stress and temperature.

About us

The NEWTE spol. s r. o. company has been on the market for more than quarter of a century now, since its establishment in 1991. This genuine Czech company initially started with applications for the food packaging industry, followed by further industries later on, dealing with the control of working machinery, production lines and related technology. Other associated activities include project engineering and the manufacture of power distribution boards, development, project engineering and production of special-purpose machinery and the custom production of electronic components. NEWTE spol. s r. o. also deals with the development of software applications for PLCs, PCs and microcomputers. The scope of our business comprises of the supply of products for automation technology, frequency modulators, sensors, special relays and pneumatic components.

We currently manufacture absolutely unique equipment suitable for quality management and control. These are the modern and innovative Stresstter 6 and Striatter 1000 devices, which are designed for the glass industry.

There is a new trend in our business, addressing tasks to utilise an efficient combination of electronics, optics and mechanics for the detection of defects or quality control focused on products or manufacturing operations.

Our priorities include high quality workmanship in our products in combination with premium materials and a hard-wearing design. We are striving to achieve the establishment and development of sound and firm relationships with both our customers and suppliers, built on mutual trust and respect.
