The WSR and WSS Wheel Detectors

The WSR (Wheel Sensor Relay) and WSS (Wheel Sensor Single) Wheel Detectors are electronic switches which respond contactlessly to wheel flanges.

The WSR Wheel Detector replaces mechanical or magnetic track-installed switching devices such as the S44, MK and WSSB-Impulsgeber without any modification to the cabling or existing evaluation equipment with a nominal operating voltage of 18 V to 60 V DC or 24 V to
60 V AC.

The WSS Wheel Detector replaces the RSE Wheel Sensor without any modification to the cabling or existing evaluation unit.

 

WSS and WSR benefits

Interface compatibility with existing wheel sensors and intermittent track-installed switching devices for switching and indication functions from Siemens in applications with nominal operating voltages of 12 V to 60 V DC or 24 V to 60 V AC
Mounting and interface compatibility with S44, MK and WSSB-Impulsgeber switching contacts (attachment at rail base)
Mounting compatibility with the RSE Wheel Sensor (same drilling dimensions)
No additional interface board required in the indoor equipment
Cabling compatibility; no separate operating voltage supply necessary (in applications with nominal operating voltages of 18 V to 60 V DC or 24 V to
60 V AC)
No electronics required in the trackside connection box
No interference from magnetic brakes and Knorr-type eddy-current brakes
Maintenance-free; readjustment is dependent on the degree of wear of the rail
Rail web or rail base clamp attachment
Rail web mounting possible over a sleeper
Semi-automatic adjustment to the mounting location
Max. traversal speed of 450 kph
Development and approval according to CENELEC
