What makes our rail sensor FORPS so unique...
is, for three, our new electronic XD-1100.

With its synchronized time stamp, a high resolution of 10 kHz, and a dynamic range of 33dB, it is state of the art engineering.

The XD-1100 has a high amplification and a high resolution, thus delivering crystal clear signals for a multitude of applications such as flat wheel detection, vibration or track bed analysis.

And unlike its analog predecessor, it is digital with a USB and RS-485 serial output and a lot of freely selectable settings for analog voltage output, amplification and so on. Additionally, it always adjusts the quiescent signal so that the system is insensitive to outer changes.

All of our FORPS sensors (FORPS UIC 60/HS, FORPS UIC 54, FORPS S 49) can be directly connected to it.

What makes our rail sensor FORPS so unique...
is, for two, the immunity against any kind of electromagnetic interference.

Sensor Line is a pioneer in the field of fiber optic technology. We have been developing fiber optic sensors for road and rail traffic for more than 20 years now.

The most crucial point of our fiber optic sensors in rail is that they are immune against electromagnetic interference in contrast to conventional systems (it eliminates the negative effects of classic electro-magnetic systems, such as electromagnetic interference).

And not only is our FORPS a fiber optic sensor, but we also have fiber optic cables with low attenuation losses leading all the way to the roadside cabinet. So there is no need for any shielding and electronics in the track area or along the track.

Using our fiber optic technology, you do not only have the advantage of lower costs (versus copper), but you also get to eliminate lightning damage and electromagnetic interference.

What makes our rail sensor FORPS so unique...
is, for one, the easy and fast installation.

You just lift the rail, put the sensor pad on the sleeper and put the rail down again, without even stopping the running train traffic. No mechanical machining is needed.

Then you connect the cables to a road side cabinet where our electronical interface is. The digital signals are being collected with a computer and sent to your server via LTE.

When you want to cover a full rail wheel, for example for flat wheel detection, usually 16 sensors are being installed, 14 normal ones and 2 with a temperature sensor. Then you might want to consider closing the track for a few hours! 😊

We have got all different sensor types available for the different rail dimensions, for example UIC 54, UIC 60, UIC 60 High Speed for TGV, S 49…

Sensor Line at Intertraffic Amsterdam 2021
Come and visit Sensor Line at Intertraffic Amsterdam in March 2021!

Intertraffic Amsterdam has been postponed for a year due to COVID-19 virus!

"Intertraffic Amsterdam is moving from 21-24 April 2020 to 23 - 26 March 2021. We, as organizer, are complying with the explicit wishes of both exhibitors and visitors to reschedule the event. The significant increase in the global spread of COVID-19 has resulted in this decision.
With the change of dates to 2021, the biennial frequency of Intertraffic Amsterdam will as of now move to the uneven years. The upcoming editions will hence be in 2021, 2023 etc."

So let's hope we will all meet in Amsterdam next year.

Sensor Line's Rail Sensor FORPS

So we are in our second winter at a test site from a big German railway operator, and so far it is looking good!
The test site (steel and wooden sleepers) is very busy and has freight traffic, too. There is hardly any wear or ageing effect noticeable, and the signals are as clear as they were in the beginning – as it should be.
Also, our new electronic that comes with the rail pad sensor, the one-channel XD-1100 turns out to be a fine piece of thoughtful engineering.
It has a synchronized time stamp and a high resolution with 10 kHz, with a dynamic range of 33dB.

Our FORPS rail sensor is able to measure the vertical impact of a train onto the rail. It picks up vibrations and shocks in a wide frequency range and is therefore well suited for train and track maintenance diagnostics.
Because of our revolutionary fiber-optic technology, it is immune to electromagnetic interference. FORPS has a very easy handling and non-invasive installation, as again shown at the test site: you could just lift the rail, put the sensor pad on the sleeper and put the rail down again, without even stopping the running train traffic.

A ready to install SL FORPS comprises the sensor pad, a fiberoptic feeder cable in a metal housing terminated with fiber optic connectors. To operate the sensor it is connected to a Sensor Line opto-electronic interface, the XD-1100.
Typical applications by our solution partners are vibration analysis, flat wheel detection, track bed analysis and axle & wagon counting, to name just a few.

Sensor Line at Intertraffic Mexico 2019

After having successfully participated in last year’s Intertraffic Mexico, Sensor Line went to Mexico again this year to take part in the biggest traffic and mobility trade event there.
Together with our regional manager for Latin America, Mr. Daniel DeVia, Sensor Line presented our family of fiber optic sensors together with the fitting electronics at our stand.

Special interest raised our new addition to our product range, especially designed frames for the Latin American market which fit into most of the existing frames.
Therefore, almost any type of sensor product can be replaced with our state-of-the-art fiber optic sensors, which have a 24 months warranty, 5 years MTBF and a vehicle detection rate of 100%.
Trade visitors were especially pleased to find out that our sensors last longer than most of the existing frame solutions, therefore need fewer replacements, a lower stock and less down time of the lanes.

Mexico has been lovely as ever, hasta la próxima vez! (Until next time!)

Sensor Line will next exhibit at Intertraffic Amsterdam in April 2020. Be sure to visit us there!
