Brief description

railway infrastructure monitoring railway maintenance railway construction

Accurate distance measurement is essential in railway
construction – for new development as well for maintenance. Speed trains of the latest generation move at maximum speeds of over 300km/h. In order to preserve the rolling stock at such strains, millimeter precise measuring is inevitable. In addition, a smooth vehicle run highly contributes to the travel convenience of the passengers.

Clearance measuring is a further important subject in construction and maintenance of railway infrastructure. For safety reasons the exact knowledge of the room available, is an absolute must.

Furthermore, the information of the utilizable room is most
important for manufacturers of rolling stock.

A company called Amberg, who is situated in Regensdorf close to Zurich, uses Dimetix DLS-C15 sensors in their measuring system called GRP3000. The Dimetix Laser Distance Sensors integrated in this device not only do
clearance control measurements but also overhead wire measurements. The sensors are fixed on a mounting bracket. Their laser beam is aligned manually to the respective object. The sensors measure contactless on any type of natural target in a distance range of up to 65m. If required, their temperature range may be extended by an optional heating device from -10°C – +40°C to -40°C – +50°C.

Customers advantages

  • Simple alignment due to visible laser beam
  • Use in rough environment thanks to robust aluminium enclosure
  • Maintenance free operation

Products used

DLS-C Series

The DLS-C distance measuring device measures absolute distances up to 500 meters on reflective foil without
contact. Due to most innovative laser technology the DLS-C has a unique accuracy of ±1.5 mm. A further
advantage of the DLS-C is the quick determination of the positions of moving objects.

The DLS-C is an optical distance measuring device. It measures, maintenance-free, distances up to 65m on natural
surfaces. It determines positions of objects that are difficult to access or may have very high surface temperatures.
Just as easily, it accurately measures distances in hazardous environments.

The DLS-C is designed to be suitable for both, heavy industrial and outdoor applications. It is constructed of a solid
metal case and provides class IP65 environmental protection. It represents a cost efficient solution even at
extreme environment temperatures as high as +50° C. Furthermore, various features make it flexible for
multiple applications in numerous industries such as automotive, paper, metal and textile.
