SPEEL 3000 Optical Length & Speed Gauge Zumbach Electronic AG
Optical Length and Speed Measurement
In highly automated production processes, length and velocity data are required for manifold purposes. For instance, measurement of operational throughput delivers essential data to control process parameters. In the manufacturing of piece-goods an automatic start and end recognition mechanism enables an autonomous length measurement.
Advantages of Optical Metrology
For a variety of materials, especially those that are hot, elastic, highly sensitive, or dough-like, 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 high-tech gauge which can be used for a wide range of applications.
Highly Accurate Measurement
The SPEEL 3000 is designed for applications requiring very high accuracy even at very high velocities. The SPEEL 3000 is available for a measuring distance of 300 mm (11.81 in). Considering the length measurement, it reaches an accuracy of 0.05% or better. The measured length is transmitted to subsequent electronics using an industry standard incremental interface. As an alternative, a 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.

Technology
The heart of the sensor system is a high-speed line scan camera that detects light reflected from the object being measured.The data processing is achieved by advanced algorithms running on a powerful signal processing platform. The sensorsystem thus shows a high degree of adaptability, and can be used on a wide range of industrial surfaces. It is even possible to detect lack of motion or direction-change in the object being measured, which are then taken into account in the measurement of distance covered.
Using built-in diagnostic LEDs, an RS232 interface, and appropriate software, extensive configuration and diagnosis possibilities are available for users, thus facilitating the start-up as well as enabling preventive maintenance.
