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.
