Prestige project
at New York State Thruway

"New York State is making historic investments building a modern transportation network worthy of the 21st century and beyond," Governor Cuomo said. "By investing in technology like cashless tolling, we are creating a safer, greener and less congested Thruway system and ensuring our transportation infrastructure is capable of supporting New York's growing economy."

Sensor Line sensors will play an elemental role in this project, by ensuring the correct classification of approximately 267 million motorists that travel the superhighway each year. The confidence in fiber optic sensor technology and the decision to use Sensor Line sensors is proof that our products satisfy the highest standards of accuracy and reliability.

The cashless tolling project at New York State Thruway is a milestone for Sensor Line's mission in becoming the producer of the single best sensor technology and ITS and ETC sub-systems, for collecting and providing vehicular characteristic data with the highest possible accuracy and reliability for traffic monitoring applications.

A very personal Sensor
for our retired employee Matthias

For many years, Matthias was the one who gave every SL PUR, EZ and EZR Sensor its shape. He operated the cast machine with marvellous precision and patience. The outcome were consistently high quality products, that our customers all over the world integrated into their intelligent transport systems.

By the end of June 2019, Matthias has left Sensor Line and started his well-deserved retirement. Instead of a golden watch as retirement gift, our employee Matthias got a golden SL PUR Sensor, signed by everyone in the Sensor Line team. Sensor Line owners Julia Knoll and Eva Dreier expressed their gratitude and wished Matthias well for a long, healthy and happy life in retirement.

Sensor Line GmbH donates 10.000,00 Euro to ELISA Family Aftercare

This year, Sensor Line GmbH donated 10,000.00 Euro to enable seriously ill children and their parents to spend a family weekend together in 2019. The aim of this family weekend is to "bring along all families who would like to go with them - no matter how badly the child is affected. This means that we also give children who need artificial respiration and / or artificial nutrition the chance to travel with us. For this reason, a doctor and children's nurses are always there to take care of the children," says Nadine Dier, Managing Director of ELISA.
The entire Sensor Line team wants to make a mark with this donation. The financial support is an important contribution to ELISA's continuing ability to do good things for the benefit of the little patients.

Intertraffic Mexico 2018

In 2018, Sensor Line participated for the first time at Intertraffic Mexico. Together with our long time associates Deviteck from Colombia and Techno Supply from Brasil we had the intention to leave a very good first impression at the exhibition. For Sensor Line and its partners, the fair was a great success where many new and promising business contacts were made. Sensor Line spotlighted its brand new classification system – SL Road System – that is an important step for Sensor Line in becoming a system provider. Alongside its SL Road System, Sensor Line displayed some of its unique and reliable Fiber Optic Road Sensors, which are noise free, EMV immune and visibility independent. However, the many new products were not the only topic for Sensor Line on the fair. In addition to its operative segment, Sensor Line discussed with interested and potential clients its forward-looking strategy for the Latin American sector in 2019. Be excited to see what else we have to offer you. For further information, you can contact us at

Innovative use of our sensors in Belgium

In 2018 SignCo successfully installed 30 stations for bicycle detection. This happened in the cities of Bruges, Gent, Antwerp, Mechelen in Belgium as well as in Eindhoven and Helmond in the Netherlands. The use of our sensitive TWIN sensors, specially developed for this purpose, for bicycles, children's bicycles and strollers shows how flexible and versatile Sensor Line sensors are. Our partner SignCo has already announced further bicycle counting stations for the year 2019.
Engineer Stijn Goossens, Director of SignCo, about Sensor Line: "The sensitivity and accuracy of Sensor Line's sensors are enormous. No matter whether an adult or a child is sitting on a bicycle, or even a stroller is driving over our stations. With these sensors, we can detect and count everything very accurately. No matter what kind of weather, day/night, materials used for the bikes or magnetic fields around the location. This makes it a very robust and accurate way of high qualitative measurements. Direction, type of passant, speed, occupancy, … it’s all known and with innovation just around the corner, we will even add extra information to it."

High speed flat wheel detection with fiber optic rail pad sensors
Sensor Line launches rail traffic management system

At InnoTrans 2018, the rail industry’s leading international trade fair, Sensor Line launches with SL Rail system a rail traffic management system for flat wheel detection. It is based on Sensor Line’s Fiber Optic Rail Pad Sensor (FORPS) and four high speed signal processing systems.
The pad sensors are easy to install, immune against EMP and deliver a highly accurate signal. The four signal processing systems acquire synchronized data with 10 kHz each. Preprocessing is done on a Raspberry Pi system on site. Results are send by wireless/wired network to SL Rail Manager and stored in a central database.
SL Rail Cockpit Monitor shows actual data and gives access to all stored data for comparison and reports. Furthermore, an interface to other customer systems is provided.

Visit us at InnoTrans in Berlin, 18 - 21 September 2018, Hall 26, Booth 206.
