Lenord+Bauer is a world-leading supplier of magnetic sensors for demanding applications in rail vehicles, windmills, mobile machines, and vehicular and marine engineering. The Sensorline product range offers a variety of sensor solutions for railway, metro and tram applications, such as:
Encoders used in rail vehicles need to be unaffected by dirt, oil and grease, rainwater, condensation, high and / or fluctuating temperatures, and shock and vibration, particularly in the unsprung parts of bogies. Lenord+Bauer sensors can take all such punishment without damage.
They have proved to be reliant in thousands of railway projects during the last decades. They are based on the magnetic and inductive sensing principles using hall-effect magneto-resistance and Eddy current sensors with metal targets and employ the very latest sensor technology, circuitry and construction techniques.
These sensors offer a high level of electrical and mechanical robustness, guaranteeing reliable function and long-term dependability.
Custom sensors, cables and hardware
For special requirements, Lenord+Bauer can design and manufacture custom sensors, and associated cable and hardware types. Almost any installation requirement can be accommodated.
Rotary speed sensors
Rail rotary speed sensors for sensing toothed wheel targets are available in a wide range of types. Features include:
For highly dynamic drive regulators in locomotives Lenord+Bauer offers high-resolution encoders with their own housing and bearings. They also possess a specially constructed wide-range coupling that can compensate for considerable amounts of play on the axial shaft.
Multi-channel encoders have been specially developed to provide independent output signals for different control electronics, such as engine rev counters, wheel-slide protection, automatic train control and rolling distance. Features include:
These encoders can be supplied in a number of variants for mounting on the axle cover or directly on the wheel with a torque converter bearing. Their flexible, modular construction makes them ideal encoders not only for new projects, but also for upgrading and retrofitting existing rolling stock.
Odometers for freight vehicles
For mileage data acquisition Lenord+Bauer offers an energy autonomous odometer for freight vehicles. The compact and maintenance-free device will be mounted to the wheel set and records extensive wheel set and mileage information. A handheld device can be used to retrieve data via RFID and transfer it to your ERP or maintenance database.
Product testing and certifications
Extensive experience has resulted in practical test strategies especially developed for Lenord+Bauer products and their fields of application. The company tests for compliance with all the usual standards as regards:
The company's quality management is certified to IRIS and ISO 9001 and its environmental management to ISO 14001.
