The P16800 simplifies the retrofitting of rail vehicles with control systems by safely (SIL2/SIL4) doubling of speed sensor signals for odometry systems.
Knick offers high isolation transducers for voltage and current measurements. The P45000 is the most space-saving high-voltage transducer with SIL 2 for DC voltage measurement on-board of all DC and AC powered trains.
At InnoTrans 2022 Knick presented 3 products as world firsts for rolling stock and DC traction power supply applications.
The new P52000VPD voltage presence detector reliably monitors areas with high voltages and sends a signal to the downstream plant control system when a specified threshold value is reached.
Applications for DC electrical transducers are encountered often within the rail industry for measurement purposes. They are prevalent on both rolling stock and substation equipment dedicated to traction power. Information afforded by voltage and current measurements is often used for control, safety, and data collection.
The reliable detection of short circuits and the proper handling of signal transmissions is not only important for smooth rail operations, but also for the safety of employees and passengers. Precision and reliability with voltage and current measurement, in addition to sound signal separation and conversion, are critical in ensuring this safety on both rail vehicles and in substations.
The requirements placed on railway vehicles have increased significantly in recent years. Products for rolling stock need to ensure a higher level of functional safety than ever before to make the travel experience more comfortable, safer and reliable for the end user – the railway customers. New technologies must be developed to meet future application requirements as well. Based on these points, Knick decided to fundamentally redesign one of its core product groups.
There are numerous features that make the P50000 series of high-voltage and current transducers a great choice for deployment within critical rail systems. What are they?
