Blacknest SURFACE was born with the objective of continuously monitoring the rail temperature, as well as the tilting and vibrations, with a simple installation. A solution adapted to the needs of train circulation and requiring very occasional maintenance that makes its installation technically and economically feasible.
It is installed directly on the rail by means of magnets. Particularly suitable for sensitive areas such as turnouts, problematic joints, or areas with significant temperature gradients. LTE-M1 communication ensures low data consumption and does not require track repeaters. The LTE-M1 card is included in the sensor and is activated remotely as soon as the sensor is installed.
