Non-contact measurement using Proton's InteliSENS

World’s first...

At 600 metres long and a voltage of 138 kV, Nexans has claimed two world records for a superconductor cable incorporated in a power grid.

Proton has launched three models of non-contact laser doppler wire and cable speed/length measuring sensors. These sensors are a direct replacement for all cumbersome mechanical wheel or belt type cable length counters, and are wear-free. In addition the sensors deliver a host of interfaces including incremental Pulse O/P’s, profiBUS, RS232, CanBUS, Ethernet IP and deviceNET.

Harmonious future for OTA technology OTA technology from Ernst Koch GmbH & Co KG is said to guarantee a particularly high quality product, and is especially suited for the production of spring steel and music wires. Twenty-five of the machines have been supplied in the two years since the introduction of this new speed control technology. The OTA lines work without tuner and dancer rolls and thus ensure a linear wire passing from the first drawing block up to the spooler. “We've noticed a continuously growing demand for the OTA machines since the introduction of the OTA technology,“ commented managing directors, Jochen Koch and Thomas Voss. “With the OTA speed control technology we've improved the productivity of our drawing machines by means of higher drawing speeds and longer operation times of the drawing dies on the one hand and achieving better quality results on the other hand.” The OTA lines are available in different sizes and models, and are suited for the processing of low and high carbon steel wires as well as of stainless materials.

The 600-metre, 138 kV, 574 MVA power link, comprising three high temperature superconductor (HTS) cable phases running in parallel, is the world’s first superconductor cable system installed in a live grid operating at transmission voltage.

Proton’s InteliSENS for cable measurement! ▲ ▲

In any cable factory there are material losses incurred of 1-2%, the result of shortages and over-lengths between intermediate processes, and the ‘giveaway over-length’ at final shipping. By offering three different sensors, Proton aims to supply a solution for “everything that moves in wire and cable,” including applications that are difficult or impossible to measure using mechanical length counters. By supplying every unit with a European wide recognised UKAS Certificate of Calibration, the Proton InteliSENS offers not only a system that is calibration-free but also has European Wide Traceability of Calibration.

Shot peening for valve and small pressure springs

Using the RDS shot peening system, shot peening of coil springs can be integrated into continuous production lines. In RDS-Mini shot peening systems, single work pieces travel on horizontal rolls through the machine at a throughput rate of over 5,000 springs an hour. Springs are fed to the machine individually on a straight-line conveyor, or other loading system, and then moved through the blasting zone on continuously rotating horizontal rolls. Cams attached to chains effect the necessary axial movements. Inside the blasting zone, the springs are guided by adjustable baffle plates, which also serve to focus the shot stream on the work pieces for optimal exposure within the ‘hot spot’ of the blast pattern. The parameters of the shot peening process, including shot quality, blast wheel speed/throwing velocity, the speed at which the work pieces rotate

and dwell time, can be regulated to suit the specific type of work piece, and it is this definition of all parameters that ensures process-safety. Process parameters can be recorded in the control system and retrieved when necessary. DISA Industrie AG – Switzerland Email : hansjoerg.stoll@disagroup.com Website : www.disagroup.com
