Overview

The rugged and maintenance-free SPEETEC laser surface motion sensor detects the movements of object surfaces without contact. This detection requires no scale or measuring elements. The laser Doppler effect based technology enables the SPEETEC to measure the speed, length, movement direction and position of objects on almost any surface. The non-contact measurement method used by the sensor makes it particularly suitable for applications with soft or sensitive surfaces that would be damaged by tactile measurement. The SPEETEC is also ideal for encoder applications with fast and dynamic processes that are unsuitable for encoders.

Advantages

Opening up new fields of application in motion monitoring

SPEETEC 1D shows what’s possible. Using the laser Doppler process, the sensor measures the length, speed and position of piece goods as well as endless materials quickly and precisely. Since it measures without making contact, it enables new applications in automation: Where direct measurements on sensitive or soft surfaces used to be avoided because tactile sensors damage them, it can now perform non-contact motion data recording with the SPEETEC. Thanks to the compact dimensions and standardized TTL or HTL interface, it is also easy to integrate into new or existing plant and can be put into operation quickly.

No measurement errors due to slip. Short response times and very high measurement accuracy in the first few centimeters: With its optical measurement principle, the SPEETEC is setting new standards in speed measurement in dynamic and clocked processes.

High measurement accuracy in start-stop operation and with short measurement lengths.

Slip-free measurements in dynamic processes increase the process quality and productivity of the plants.

Smart design

The long laser window and the rounded edges indicate the direction of movement.

High-quality plug connectors meet minimalistic and functional design.

The clear and elegant design of the SPEETEC was presented the iF Design Award 2020.

Increases the measurement horizon: SPEETEC closes the gap between tactile measuring wheel systems and complex laser Doppler sensors – and is suitable for almost all surfaces and objects thanks to the non-contact measurement.

More convenient handling – safety with laser class 1 from the factory

The SPEETEC is much more economic than other laser speed sensors: Thanks to laser class 1, no protective measures such as housing, eye protection and safety areas are required for integration of the device, and no specially trained staff is needed. Installation work is minimal: Simply mount and go. The laser Doppler process of the infrared laser delivers exact speed values of up to 10 m/s with very high repeatability. Whether endless materials or piece goods – the high resolution of the laser enables a maximum resolution of 4 µm and, on a path of one meter, the sensor measures material lengths down to the last millimeter. It therefore offers maximum reliability for countless applications.

Practical technology

The infrared laser measures with a wavelength of 850 nm outside visible light.

Thanks to laser class 1, damage caused by laser beams is ruled out – even with direct eye contact.

The optical sensor of the SPEETEC is insensitive to ambient light and always delivers reliable measured values.

High-precision, reliability and very simple use: The SPEETEC makes laser class 1 the new standard for non-contact speed measurement.

Gentle and economic measurement of sensitive surfaces

The measurement system is specially suited for the measurement of particularly sensitive materials. Surfaces which get dented or damaged or undergo material changes due to the contact pressure of conventional measuring wheel systems can now be measured simply and reliably. The laser-based technology also prevents contamination on the material surface to be measured. In addition to movements of endless materials, the SPEETEC also precisely detects movements of piece goods without a problem. In addition, the laser is wear-free, ensuring more process reliability with minimal maintenance costs.

Smooth speed measurement: The SPEETEC enables exact non-contact movement measurement on very soft and sensitive surfaces, and with minimal maintenance effort.

With precise length values of piece goods, the SPEETEC delivers the foundation for automated statistical process control, optimal processes and cost-effective system control.

The SPEETEC detects positions on piece goods. As a result, it is possible to process piece goods at the right position.

Measurements which are gentle on materials

The optical sensors prevent damage to especially sensitive materials such as thin film, soft rubber or insulating material.

The SPEETEC measures without wear and delivers reliable and exact values after many thousands of hours of use.

Mounting the trigger sensor directly on the housing of the SPEETEC enables exact length measurement of piece goods.

Smooth speed measurement: The SPEETEC enables exact non-contact movement measurement on very soft and sensitive surfaces, and with minimal maintenance effort.
