Survey of Railway Infrastructure

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, precise millimeter measurement is crucial. In addition, a smooth vehicle run at maximum capacity 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, situated in Regensdorf close to Zurich, uses Dimetix sensors in their measuring system called GRP3000. The Dimetix Laser Distance Sensors integrated in this device not only do clearance control measurements but overhead wire measurements as well. The sensors are fixed on a mounting bracket.

Customer Advantage Easy installation thanks to visible laser beam Easy configuration thanks to the free software Operation in the largest temperature range (-40°C to +60°C) possible Measuring ranges up to 100 m on natural surfaces  Measuring ranges up to 500 m on reflective foil Accuracy ± 1 mm Repeatability ± 0.3 mm Maintenance-free operation

DIMETIX APPLICATION EXAMPLE

Dimetix Sensors – the solution for applications with high precision requirements

Thanks to the clearly arranged product portfolio the evaluation of a suitable Dimetix distance laser sensor is simple and uncomplicated. Dimetix sensors offer numerous features, which are integrated in each and every device as standard, including, among others, various interfaces like SSI, RS-422/485, RS-232 and 2 digital outputs. Optionally, the Industrial Ethernet interfaces PROFINET, EtherNET/IP and EtherCAT are also available. Furthermore, all devices are IP65-protected and impress with a weight of less than 500 grams! 

Particularly noteworthy, however, is the accurate measurement of 1 millimeter over distances of up to 500 meters, even under the most extreme conditions. This is possible with the sensors of the types DPE, DEN and DEH.

No less interesting are sensors of types DAE, DAN and DBN. Preferably, they can be used for projects which do not require a range over 500 meters or are cost-sensitive.
