Goal – Create Energy From Ocean Waves
The Wave Energy Prize aims to promote the development of more wave energy converters, which they hope will reduce the cost of wave energy and make it more competitive with traditional forms of energy. Mocean Energy’s 1/50th scale model will be tested and evaluated in a wave tank in the US for a prize of $1.5 million. Their full scale version aims to convert wave force into electricity.
YDNS Miniature Reaction Torque Sensor Benefits
- Capacities: 0-0.2Nm to 0-1000Nm
- 1.3mV/V Output
- Non-Linearity: <±0.1%/Rated Capacity
- Very Compact Size
- Low Cost
- Suitable for Low Torque Measurements
- Static or Semi-Rotary Applications
“The YDNS miniature reaction torque sensor was ideal to use in this application as it can effectively measure torque to 0.1% accuracy in static or semi-rotary applications, where less than 1 revolution is to be measured,”says Ollie Morcom, Applied Measurements’ Sales Director.
Its compact size and in-line direct drive measurement capability meant it could easily be housed within the waterproof enclosure of the 1/50th scale wave energy converter. What’s more, the versatile torque sensor can also be supplied with custom shaft sizes and configurations to suit your application.
How Was It Used In The Wave Energy Converter?
To take the torque readings a YDNS miniature reaction torque sensor is connected to the motor with a coupling. When the wave force creates motion between the bodies, the rotation of the hinge (flex) applies a torque through the miniature torque sensor which turns the motor shaft. The torque sensor’s output signal is conditioned by an SGA strain gauge amplifier into a high-level ±10Vdc industry-standard signal ready for evaluation by a data acquisition system.
