Intelligence for track sensors
The Scheidt & Bachmann axle counting system is in current use thousands of times across Europe and guarantees safe railway operation. It is used in both the ZSB 2000 interlocking and the BUES 2000 level crossing protection system. The system works self-intelligently and communicates digitally with the BUES 2000. Our axle counting system reports the number of detected axles and their direction to the level crossing, the interlocking, or a train detection system, which takes over the evaluation of this information and initiates the appropriate reactions. A system always consists of:
Axle sensors
An axle sensor consists of two induction loops, which are installed in a compact, impact-resistant and waterproof plastic housing and evaluated in an axle-sensitive manner due to their linear expansion. The component is clamped to the rail with a universal fastening and can be mounted and dismounted very easily.
Axis sensor evaluation unit
The axis sensor evaluation unit evaluates the inductive damping of the axis sensor and digitally transmits each detected axis with the corresponding direction to the superior system. The system, consisting of the axle sensor and the evaluation module, can also be used as a feedback signal. In this case, the feedback signal is output as a galvanically free contact. A digital connection to a superior system is not necessary here.
Equipment:
▪ Axle sensor as double induction loop
▪ Impact-resistant and waterproof plastic housing
▪ Universal fastening for clamp mounting on the rail
▪ Track connection housing with connection distributor, connection plate and cable gland
▪ Axis sensor evaluation module for controlling and evaluating the axis sensor signals and for communication with the superior system
Further features:
▪ Low linear expansion in the track
▪ Maintenance-free system
▪ Universal fastening, regardless of rail shape
▪ Easy mounting and removal
▪ No adjustment after dismantling the axle sensor (e.g. due to tamping work)
▪ Independent of superstructure and thus sleepers
▪ Simple installation without drilling work on the rail
▪ Only one sleeper compartment distance to other elements in the track necessary
▪ Continuous and intelligent evaluation directly on the track with automatic recalibration
▪ Self-diagnostic system with automatic fault indication
▪ Connection of manual control buttons directly to the axle sensor evaluation assembly possible
▪ Approval up to 160 km/h, i.e. 100 mph
Consistent train detection
In addition to the Scheidt & Bachmann axle sensor system, we also have the proven and maintenance-free Scheidt & Bachmann 60/80 vehicle sensor, which enables direction-dependent train detection. This train detection system is based on the design principle “simple sensor, intelligent evaluation” and combines the advantages of a simple inductive sensor with the possibilities of digital evaluation.
