2-6-axes diameter gauge with measurement range 120/150 mm
The standard model ATON Bar is a bar and tube gauge for round profiles. It measures diameter and ovality with 2,3,4 or 6 axes shadow sensors, has a measurement range 120 mm and an accuracy of 15 µm. The 4 and 6 axes version can also visualize rolling defects such as roll shift, over and under fill. With the 3 and the 6 axes version the gauge can measure trilobed rounds, coming from 3-roll mills. The 6-axes version is also able to measure rebar structures with core diameter, rib height and meter weight.
The ATON Bar software shows beside the current measured diameter values from the different axes a polar diagram of the interpolated cross section during the measurement. In a linear diagram, diameters from the different axes, minimum/maximum diameter and ovality are displayed over the length of the billet. The material temperature is also measured by a built-in pyrometer, in order to calculate the cold dimensions using the material’s shrinking coefficient. Rolling speed can be measured from a suitable analogue or digital speed signal.
Retrieval of historic data is possible by a finger click. A diagnosis screen informs about the health of the system. Remote access for maintenance or trouble shooting is possible through the network connection.
Benefit from higher yield and higher utilization by choosing an ATON Bar system. Choosing a sophisticated dimensional measurement system allows for maintaining dimensional accuracy over the entire coil length and enables you to take immediate corrective actions after the detection of deviations.
All housings of ATON Bar have active cooling and purge air. ATON Bar 120 is specified for material up to 100 mm (maximum pass line variation ±10 mm), ATON Bar 150 for material up to 130 mm (maximum pass line variation ±10 mm), both at up to 1200 °C. All versions of ATON Bar gauge can compensate the expansion of high temperature material using temperature data from an external pyrometer and calculation of the shrinking based on temperature coefficients provided by the customer.
