Perpetuum has extended its range of vibration energy harvesters to support a new design of train monitoring systems.
The company recently announced successful trials which demonstrated the ability to power monitoring of bearings in everything from high speed trains to freight wagons.
"Providing power at a very low installed cost on passenger train bogies and freight wagons, this technology now makes wireless installation possible with a massive cost savings and improved reliability compared with hard wiring or the high cost of installing axle generators in freight wagons," said the company.
The products can cover a range of power outputs and are designed to meet the different requirements of both passenger trains and freight wagons.
The range of PMG RAIL products can now be tailored to provide power for a range of monitoring and wireless data transmission.
Typical applications will include bearing monitoring, GPS location tracking and wheel condition monitoring. Wireless comms links will be via 802.15.4 networks on vehicles and along trains, low power 802.11 and GPRS/GSM/GSM-R.
