Wheel Sensors and Wheel Detection Systems by Frauscher
At present, inductive wheel sensors by Frauscher are used in more than 100 countries around the world. In combination with perfectly compatible evaluation boards, they constitute highly reliable wheel detection systems. Their applications range from simple switching tasks or level crossing protection to fail-safe track vacancy detection.
Alongside a broad spectrum of applications, wheel detection systems and wheel sensors by Frauscher are popular with customers around the world because of their convenient handling. Patented rail claws and plug-in connections – available with some sensor models – make the process of mounting Frauscher Wheel Sensors a quick and easy task. Moreover, they can be used on a range of globally known rail shapes, which tend to vary between rail segments. Optimised maintenance cycles and low maintenance costs additionally minimise life cycle expenses.
Wheel Detection Systems
Presence, speed or direction of an axle: Frauscher Wheel Sensors reliably detect these and other data under all climatic, technical and operational conditions. Their maximum availability results from a combination of robust design, high-quality components and an exceptionally reliable basic technology.
Analogue sensor signals are safely evaluated by way of prefabricated evaluation boards by Frauscher. These can optionally be positioned either centrally in the interlocking or in a decentralised architecture in cubicles along the rail line. The benefit: No active electronic components are placed on the track itself.
Optimum coordination of these boards with Frauscher Wheel Sensors facilitates the implementation of safety-relevant applications. That’s how standards up to CENELEC SIL 4 are met. For non-vital and individual solutions, sensors with an open interface are available.
Highest availability, easy operation and low maintenance needs. Those are only three of the many characteristics that customers worldwide value in wheel sensors by Frauscher. When delivered without evaluation board, connection to the customer application takes place via open analogue interfaces. This allows for a multitude of different areas of application.
Two independent sensor systems in a single housing – this design minimises the weight of Frauscher Wheel Sensors. When convenient rail claws are used for easy mounting of the sensors, this in turn increases the service life of supporting components.
Speaking of mounting: The compact design also enables the mounting of Frauscher Wheel Sensors on the inside along the track. That’s where they reliably detect the flange of passing wheels. Moreover, they supply – not least because of their design – important additional information about:
- Traversing of an axle
- Direction of travel
- Wheel centre pulse
- Wheel diameter
The RSR180 combines tried and tested technology with decades-long experience. As the first wheel sensor in our portfolio, it has undergone continual development over more than 30 years. Today, its area of application ranges from open lines to grooved rails around the globe. In addition, this universally applicable sensor is highly resistant to interferences caused by electromagnetic rail brakes.
Benefits of the RSR180:
- Time-proven technology
- Universally applicable
- No sensor adjustment needed
Based on the patented V.Mix Technology, the RSR123 combines various inductive methods. This makes the Frauscher Wheel Sensor highly resistant to electromagnetic interferences caused by eddy current brakes or rail currents, for instance. The RSR123 comes with a plug-in sensor cable. The sensor’s adjustment is automatically carried out by the indoor equipment.
Benefits of the RSR123:
- Highly resistant to electromagnetic interferences
- Convenient plug-in connections
The RSR110 Wheel Sensor comes in two system variants, as Single Wheel Sensor RSR110s and Double Wheel Sensor RSR110d. Both wheel sensors are available without evaluation board and can be easily integrated into the electronics of any system via an open analogue interface. This allows system integrators to customise the evaluation of the data according to their individual requirements. If needed, the Wheel Sensor Converter WSC helps convert the analogue signal into a digital one.
Benefits of the RSR110:
- Open analogue interface
- Easy to integrate
- Simple and fast installation
- High availability
- Very precise data
SENSiS Detection Point SDP
The SDP, Frauscher’s latest wheel sensor, creates an active link between interlocking and line: It acts as a smart trackside device. The inductive sensor signal and data from additional temperature and acceleration measurements are digitalised right on track. A specifically developed bus system enables cabling to be configured in the form of a ring architecture, which significantly reduces the length of cable needed. Via the network that is created, the SDP then transmits information to the indoor equipment. At the same time, the indoor equipment can transmit data back to the field sensor.
Benefits of the SENSiS Detection Point SDP:
- Digital output
- Valuable additional information
- Reduced need for components
- Network capabilities
