|
Cable Guidance and Sensor Tripod with Laser Protection Casing µSPEED-CGS |
The cable guidance with tripod for the μSPEED sensor (μSPEED-CGS) always ensures the correct distance between the cable and the sensor as well as the correct routing of the cables. When the laser protection casing is opened, the laser switches off automatically. | 
|
Laser Protection Equipment |
|
Laser Protection Tube µSPEED-TUBE |
The sensor head TUBE for the μSPEED sensor reduces the risk of direct exposure of the laser beam. The TUBE can be combined with the laser shutter LSH. | 
|
|
Laser Shutter µSPEED-LSH |
The laser shutter μSPEED-LSH is used for the mechanical blocking of the laser beam. The shutter is manually activated by means of a sliding mechanism and is mounted on the front of the μSPEED system with four screws. | 
|
|
Angule Optics µSPEED-AO |
The angle optics AO is used when the existing mounting space is very limited. The 90° angle optics makes it possible to manage with minimal space. |
|
|
Laser Protection and Safety Monitoring µSPEED-LSSC |
The laser protection safety monitoring links various monitoring sensors to avoid any danger from the μSPEED laser. Laser class 1 may be achieved in conjunction with other protective measures. |  |
Lable Printer |
|
Printer for connecting to the MID-COUNTER µSPEED-PRT |
In some applications there is a need to provide the product measured in length directly with a label which contains the essential measurement data. This is done by the printer μSPEED-PRT. |  |
Radio Data Transmissions |
|
Bluetooth Module µSPEED-BT |
With the Bluetooth module, the measurement data can be transmitted over a radio link. Such a solution is used when the measurement system with μSPEED-T-Box is not accessible during production. A typical application is in roping/stranding machines. |  |
Battery Module for self-sufficient system operation |
|
Battery Module and Data Logger µSPEED-ACU µSPEED-DTL |
For completely self-sufficient system operation, the μSPEED sensor is powered by a battery module together with a data logger. A field of application is the speed measurement of sports vehicles, where there is often no power supply. |  |
Laser-Encoder Lenght Measurement Systems and Speed Measurement Systems
By means of two laser beams, a bar pattern is generated on the material measurement surface. The movement of the surface of the measurement material modulates the intensity of the backscattered light into the detector, the frequency of the brightness modulation being directly proportional to the speed of the medium and to the Doppler frequency. The scattered light is converted into an electrical signal via a photodetector and fed via an analog / digital converter to a processor. The processor determines the current speed and path length from the digitized signal. The use of marks or scales on the test object is not necessary. The procedure is known by the name of “Laser Surface Velocimeter – Laser Doppler Measurement System”.
