^Title Wireless Telemetry Strain Measurement of Wind Turbines

The gauges were positioned along the surfaces of the prototype blades. The rotation of the blades and height of the turbine made a wired solution impractical accompanied by the clients request to re-use the system on several prototype blades.

The solution came in the form of 14 x waterproofed T24-ACMi with strain gauge input wireless sensor converter module. The modules all reported back to a single PC with one base station. They were all set to the same channel and provided readings 100 times per second. The T24-TK telemetry toolkit was used to monitor the data from all 14 x acquisition modules and log the data back to a CSV (comma separated variable file). Due to transmission collisions and the finite bandwidth of the telemetry system, only 25 to 30 readings were recorded from each of the 14 x acquisition modules every second, however the clients requirement was for only 10 readings per second. If a higher frequency of readings had been required, a single PC with multiple base stations on separate channels could have be deployed.
