To ensure that modern train control systems receive reliable rotational speed signals, vehicle operators have to regularly replace passive sensors with active ones. Our screw-in threaded sensors are used to upgrade rail vehicles to the state of the art to enable continued operation.

Space-saving assembly variant

In addition to tried-and-tested speed sensors with flange housing, threaded sensors with one or alternatively two channels are another assembly variant for threaded or through holes. These spacesaving sensors can be easily integrated into existing designs without any mechanical adjustments thanks to standard thread types and nominal lengths as well as individual cable fabrication.

They acquire the rotational speed and direction of rotation directly at the motor or gearbox and detect even the smallest movements of the drive with a measuring range of 0 Hz to 20 kHz. Robust, high-resolution sensors were developed for use in the harshest ambient conditions. They are suitable, for example, for traction control and train protection. The maintenance- and wear-free magnetic measuring system in the thick-walled stainless steel housing withstands both shocks and vibrations. Certification in accordance with DNV GL, SIL, ATEX or IECEx is possible as an option.
