Non-contact length ▲ ▲ measurement from Zumbach

The measured length is transmitted to subsequent electronics using an industry standard incremental interface. An alternative synchronous serial interface (SSI) is also available. In addition, an electrical output signal compatible with common incremental encoders is available and can be directly connected to control systems, electrical counters or frequency inverters. • Speed range up to 3,000m/min • Detection of standstill • Detection of direction • Start and end recognition • Allows deviation of the measuring distance • Suits smooth and rough surfaces • Long life LED illumination • Maintenance free Zumbach Electronic AG – Switzerland Fax : +41 32 356 0430 Email : sales@zumbach.ch Website : www.zumbach.com The main features of Speel 3000 include:

In highly automated production processes measurement of operational throughput delivers essential data to control process parameters or, as in the manufacturing of piece goods, an automatic start and end recognition mechanism allows autonomous length measurement. When working with hot, elastic, highly sensitive or dough-like materials, it is impossible to use tactile sensors such as odometers or tacho rolls. The accuracy of a mechanical sensor system is also reduced by slippage, which in practice can lead to measuring errors of 10% or more. In both cases, non-contact optical metrology provides significant benefits. With the Speel 3000, Zumbach offers a gauge that can be used for applications that demand a high degree of accuracy at high velocities. Speel 3000 is available for a measuring distance of 300mm and is said to achieve an accuracy of 0.05% or better.
