Trains provide a sustainable source of vibration energy to power sensors, at least while they are moving. Testing has shown that the vibration spectra generated by train wheels was sufficient to allow Perpetuum’s energy harvester to generate 10s of mW of electrical energy – a level sufficient to power sensors to monitor the condition of wheel bearings.
Optimized to deliver the highest power output from vibration frequencies between 30Hz – 60Hz that are typical to the rail industry, Perpetuum’s PMG Rail operates in the temperature range from -40°C to 85°C (-40°F to 185°F) and has factory programmed voltage outputs from 3V – 10V.
Other monitoring and sensing applications for the PMG RAIL products include:
– Bearing Monitoring
– GPS Location Tracking
– Hazardous Cargo Monitoring (Temperature, Pressure, “Door Open”)
– Wheel Condition Monitoring (Flats, Cracks)
– Braking System Monitoring
