Triggering Track Side Equipment

Benefits for operators

When used for triggering track side equipment, the latest Frauscher wheel sensor RSR110 offers numerous benefits spanning a range of different types of equipment applications.

  • High uptime and reliability
  • Low maintenance
  • Quick and easy Installation
  • Low power consumption

High Uptime and Reliability

The combination of different inductive operating principles and the robust design of the RSR110 guarantee high availability, even when subjected to extreme mechanical, electromagnetic, climatic or environmental interference. Features that support high uptime include:

  • Robust design: Our wheel sensors can function in the most remote areas under severe conditions because they are unaffected by extreme environmental conditions, including ice, heavy rain, hail, heat, snow or flooding.
  • Highly EMI resistant: Our sensor technology is highly reliable, even when subjected to numerous extreme types of electromagnetic interference caused by various potential factors, including eddy currents, magnetic track brakes or other onboard devices.
  • Unaffected by track return current: Our wheel sensors are unaffected by track return current, therefore eliminating the need for insulated track joints and opening up the option for using highly stable welded joints. Also, all types of ties, including wood, steel and concrete, can be used without any effect on the detection system.
  • Independent of ballast resistance: Various environmental conditions that can cause leaks on the tracks, including wet stones, leaves, dirt and dust, negatively affect track circuits. Our axle counters are independent of the ballast, making them unaffected by these conditions.
  • CENELEC standards: All of our production processes comply with CENELEC standards, ensuring process quality of the highest caliber. The availability of RSR110 is A = 99.99996% or > 1,000,000 h MTBF (Mean Time Between Failures).

Low Maintenance

Our wheel sensors do not depend on regular traversing cycles. As no active electronic components are mounted to the track, the system also remains highly reliable on low-traffic lines. The only preventive maintenance, that our wheel sensors require is an inspection every two years.

The easy installation, dismounting and calibration features save huge maintenance efforts during the whole life cycle of the sensors. For example, dismounting wheel sensors in case of tamping can be done very easily. Only one nut has to be opened and the wheel sensor can be removed together with the rail claw. Given that the cable to the wheel sensor is pluggable, track maintenance becomes easier.

Quick and Easy Installation

All Frauscher wheel sensors can be installed, dismounted and replaced very easily and quickly using the following methods:

  • Patented rail claw: Frauscher has consistently adopted the use of rail claws in the mounting of its wheel sensors in order to make use of these sensors more flexible and cost-effective. Both the vignole rail claws and grooved rail claws are characterized by optimum flexibility and precision in mounting. Sensors can be aligned vertically or horizontally from a remote location, allowing for optimum sensor position and performance. The adjustment of sensors in vertical and horizontal directions is a labor-saving feature, and the ability to quickly adjust as rail wear occurs ensures that sensors are not hit by wheels and extends their long life on the track.
  • Automated Calibration: Calibrating the wheel sensor can be done within 20 seconds using an automated procedure and our adjustment and maintenance box (AMB). There is no mechanical intervention needed. Furthermore, it’s also possible to complete this process remotely. No re-calibration is needed in case of an interruption of the power supply. This saves significant time and reduces maintenance resources considerably.
  • Cable connections: The connection of the wheel sensor cable to the cable system can be implemented via a trackside connection box. This contains nothing more than a clamping terminal, which does not require the use of any additional electronics in the vicinity of the track. Alternatively, it is also possible to connect the sensor cable to the system using a plug-in connection.
  • Different versions of sensor cable: The plug-in connection cables for the RSR110 are available in a variety of versions. The sheath is available either as a tried-and-tested EPDM protection tube, a reinforced corrugated tube or a metal protection tube. Other specific types are also possible for use under particular conditions. In addition, it is possible to vary the length of the cable according to requirements.

Low Power Consumption

Our wheel sensor operates on low power at just 2 x 40 mW. In addition to low operation costs, this enables the use of solar panels in remote areas and batteries for mobile equipment power supply.
