Every construction must be controlled and monitored to ensure safety and quality, both during construction and throughout the life of the construction. With laser sensors from Dimetix AG, a wide range of needs can be covered to ensure these aspects of measurement in civil engineering.
Many of our clients around the world need to monitor the displacements between pillars and the arching after the construction of bridges. By installing our high-precision sensors: DPE 10-500 and with the profinet communication module, they achieve a reliable reading with an error of +/-1mm.
Thanks to the versatility of our sensors to measure long distances without contact, they can be integrated into your own telematics management software.
Another need is to monitor the evolution of pillars during the construction of buildings or the verticality of the same. In this case, Dimetix laser sensors were installed to monitor the evolution of the pillars under a bridge since buildings were being built and the bridge had to be kept in place. This was done with motion and temperature control to ensure that everything was kept under control.
Another practical case is the measurement of the circumference of tunnels and analyzing their stability or how external pressure affects the diameter of the tunnel.
Some manufacturers have installed our laser sensors on either tunnel boring machines, mobile triangulation machines or fixed sites to monitor tunnel circumference and long-term stability or to check parallelism between tracks and wall, such as the Amberg GRP3000 model at a speed of 2km/h.
Through triangulation, very valuable and necessary data can be obtained to know how a work is evolving.
Finally, our sensors are also used to monitor slopes, both for safety, during construction, and in areas with a high risk of earth movement or avalanches.
Dimetix laser sensors have been used in several countries to monitor the evolution of mountains during rainy seasons, volcanoes, slopes or large rocks at the roadside or to measure the level of snow. With this data, actions can be taken to avoid catastrophes that have a cost for people or infrastructure.
Customer benefits with laser sensors from DIMETIX AG

Dimetix sensors offer numerous features, which are integrated into each and every device as standard, including, among others, various interfaces such as SSI, RS-422/485, RS-232 and 2 digital outputs. Optionally, industrial Ethernet interfaces are also available: PROFINET, EtherNET/IP and EtherCAT. In addition, all devices have IP65 protection and a weight of 500gr thanks to their aluminium housing.
We are proud of the Swiss precision of 1 millimetre at distances up to 500 metres, even in the most extreme conditions, depending on the model purchased.
We calibrate and test the 100% sensors and electronics one by one. We place the sensors in a climate cabinet with temperatures from -40ºC to +70ºC to calibrate the thermal drift with 2,000 readings per sensor and then we do the longitudinal calibration on our 40m long mobile calibration bench and finally according to the sensor model with a fixed point at 500m.
For more information, please contact us and we will inform you which models may best suit your needs.
