Andre Beste, Technical Marketing Manager at Temposonics GmbH, explains in an interview why the magnetostrictive MHRM linear position sensors are predestined for a wide range of railroad applications and why they meet the needs of the industry.
The position sensors for the railway market are based on our well-known MH series, which was developed specifically for mobile hydraulics applications. With the MHRM, our customers in the railway industry get the same qualities, features and benefits that other users have already experienced in their mobile systems. In addition, the new sensor has a very compact design and operates wear-free, resulting in increased application lifetime.
Our patented magnetostrictive Temposonics® technology, used in all MH Series sensors, also ensures that MHRM sensors are robust against vibration, shock, dust and electromagnetic interference. This allows them to be used in the most challenging applications with no downtime.
All in all, the position sensors, due to their characteristics and technology, are perfectly suited for use in railroad applications.
In which railway applications are the position sensors used?
The MHRM sensors have been specifically optimized for a wide range of applications in the railway market. They can be used in commuter trains as well as in city trains or high-speed trains and provide accurate and high-quality values for the user everywhere.
Specifically, we are talking about the use of the sensors for inclination control, for the damping unit, in the pantograph or in rail maintenance vehicles, such as rail grinders or track tamping machines.
To what extent have the properties of Temposonics sensors been adapted to withstand the harsh conditions of railway installations?
Sensors for railway applications, compared to other mobile hydraulic applications, must of course meet different standards and specifications. We have designed the sensor precisely to meet the requirements of the market. Thus, it meets the requirements for shock, vibration and EMC according to DIN EN 50155 and offer shock resistance according to DIN EN 61373 Cat2 (bogie) and Cat3 (axle) as well as vibration resistance according to IEC 60068-2-64-Fn Cat3 (axle).
